AGPLv3 and GPLv3 are identical except for the marked sections of text.

  1. indicates text different in the other license;
  2. indicates text not present in the other; and
  3. indicates where additional text is present in the other.

The differences occur in the Preamble (§1), Terms and Conditions §(2.)13 and §(2.)14, and How to Apply These Terms to Your New Programs (§3).

Large stretches of identical text are highlighted like this paragraph.

The unnumbered top-level headings have been interpreted as defining top-level sections, and are displayed here with faint square-bracketed numbers that are not in the original. Earlier versions of this page numbered these top-level sections with decimal numbers rather than roman numerals.

§I¶1§I¶1ṣ1The GNU Affero General Public License is a free, copyleft license for software and other kinds of works, specifically designed to ensure cooperation with the community in the case of network server software.

§I¶2§I¶2ṣ1The licenses for most software and other practical works are designed to take away your freedom to share and change the works. §I¶2ṣ2By contrast, our General Public Licenses are intended to guarantee your freedom to share and change all versions of a programto make sure it remains free software for all its users.

§I¶3§I¶3ṣ1When we speak of free software, we are referring to freedom, not price. §I¶3ṣ2Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.

§I¶4§I¶4ṣ1Developers that use our General Public Licenses protect your rights with two steps:

  1. (1) ṣ1.1assert copyright on the software, and
  2. (2) ṣ1.2offer you this License which gives you legal permission to copy, distribute and/or modify the software.

§I¶5§I¶5ṣ1A secondary benefit of defending all users' freedom is that improvements made in alternate versions of the program, if they receive widespread use, become available for other developers to incorporate. §I¶5ṣ2Many developers of free software are heartened and encouraged by the resulting cooperation. §I¶5ṣ3However, in the case of software used on network servers, this result may fail to come about. §I¶5ṣ4The GNU General Public License permits making a modified version and letting the public access it on a server without ever releasing its source code to the public.

§I¶6§I¶6ṣ1The GNU Affero General Public License is designed specifically to ensure that, in such cases, the modified source code becomes available to the community. §I¶6ṣ2It requires the operator of a network server to provide the source code of the modified version running there to the users of that server. §I¶6ṣ3Therefore, public use of a modified version, on a publicly accessible server, gives the public access to the source code of the modified version.

§I¶7§I¶7ṣ1An older license, called the Affero General Public License and published by Affero, was designed to accomplish similar goals. §I¶7ṣ2This is a different license, not a version of the Affero GPL, but Affero has released a new version of the Affero GPL which permits relicensing under this license.

§I¶8§I¶8ṣ1The precise terms and conditions for copying, distribution and modification follow.


0. §II.0Definitions.

§II.0¶1§II.0¶1ṣ1This License refers to version 3 of the GNU Affero General Public License.


§II.0¶2§II.0¶2ṣ1Copyright also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.

§II.0¶3§II.0¶3ṣ1The Program refers to any copyrightable work licensed under this License. §II.0¶3ṣ2Each licensee is addressed as you. §II.0¶3ṣ3Licensees and recipients may be individuals or organizations.

§II.0¶4§II.0¶4ṣ1To modify a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. §II.0¶4ṣ2The resulting work is called a modified version of the earlier work or a work based on the earlier work.

§II.0¶5§II.0¶5ṣ1A covered work means either the unmodified Program or a work based on the Program.

§II.0¶6§II.0¶6ṣ1To propagate a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. §II.0¶6ṣ2Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.

§II.0¶7§II.0¶7ṣ1To convey a work means any kind of propagation that enables other parties to make or receive copies. §II.0¶7ṣ2Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.

§II.0¶8§II.0¶8ṣ1An interactive user interface displays Appropriate Legal Notices to the extent that it includes a convenient and prominently visible feature that

  1. (1) ṣ1.1displays an appropriate copyright notice, and
  2. (2) ṣ1.2tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License.

§II.0¶8ṣ2If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.

1. §II.1Source Code.

§II.1¶1§II.1¶1ṣ1The source code for a work means the preferred form of the work for making modifications to it. §II.1¶1ṣ2Object code means any non-source form of a work.

§II.1¶2§II.1¶2ṣ1A Standard Interface means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.

§II.1¶3§II.1¶3ṣ1The System Libraries of an executable work include anything, other than the work as a whole, that

  1. (a) ṣ1.ais included in the normal form of packaging a Major Component, but which is not part of that Major Component, and
  2. (b) ṣ1.bserves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form.

§II.1¶3ṣ2A Major Component, in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.

§II.1¶4§II.1¶4ṣ1The Corresponding Source for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. §II.1¶4ṣ2However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. §II.1¶4ṣ3For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work.

§II.1¶5§II.1¶5ṣ1The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.

§II.1¶6§II.1¶6ṣ1The Corresponding Source for a work in source code form is that same work.

2. §II.2Basic Permissions.

§II.2¶1§II.2¶1ṣ1All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. §II.2¶1ṣ2This License explicitly affirms your unlimited permission to run the unmodified Program. §II.2¶1ṣ3The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. §II.2¶1ṣ4This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.

§II.2¶2§II.2¶2ṣ1You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. §II.2¶2ṣ2You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. §II.2¶2ṣ3Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.

§II.2¶3§II.2¶3ṣ1Conveying under any other circumstances is permitted solely under the conditions stated below. §II.2¶3ṣ2Sublicensing is not allowed; ṣ2.1section 10 makes it unnecessary.

3. §II.3Protecting Users' Legal Rights From Anti-Circumvention Law.

§II.3¶1§II.3¶1ṣ1No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.

§II.3¶2§II.3¶2ṣ1When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.

4. §II.4Conveying Verbatim Copies.

§II.4¶1§II.4¶1ṣ1You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that

  • ṣ1.1you conspicuously and appropriately publish on each copy an appropriate copyright notice;
  • ṣ1.2keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code;
  • ṣ1.3keep intact all notices of the absence of any warranty;
  • ṣ1.4and give all recipients a copy of this License along with the Program.

§II.4¶2§II.4¶2ṣ1You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.

5. §II.5Conveying Modified Source Versions.

§II.5¶1§II.5¶1ṣ1You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:

  1. a) §II.5¶1.a§II.5¶1.aṣ1The work must carry prominent notices stating that you modified it, and giving a relevant date.
  2. b) §II.5¶1.b§II.5¶1.bṣ1The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. §II.5¶1.bṣ2This requirement modifies the requirement in section 4 to keep intact all notices.
  3. c) §II.5¶1.c§II.5¶1.cṣ1You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. §II.5¶1.cṣ2This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. §II.5¶1.cṣ3This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
  4. d) §II.5¶1.d§II.5¶1.dṣ1If the work has interactive user interfaces, each must display Appropriate Legal Notices; ṣ1.1however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.

§II.5¶2§II.5¶2ṣ1A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an aggregate if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. §II.5¶2ṣ2Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.

6. §II.6Conveying Non-Source Forms.

§II.6¶1§II.6¶1ṣ1You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:

  1. a) §II.6¶1.a§II.6¶1.aṣ1Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
  2. b) §II.6¶1.b§II.6¶1.bṣ1Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either
    1. (1) ṣ1.1a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or
    2. (2) ṣ1.2access to copy the Corresponding Source from a network server at no charge.
  3. c) §II.6¶1.c§II.6¶1.cṣ1Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. §II.6¶1.cṣ2This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
  4. d) §II.6¶1.d§II.6¶1.dṣ1Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. §II.6¶1.dṣ2You need not require recipients to copy the Corresponding Source along with the object code. §II.6¶1.dṣ3If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. §II.6¶1.dṣ4Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
  5. e) §II.6¶1.e§II.6¶1.eṣ1Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.

§II.6¶2§II.6¶2ṣ1A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.

§II.6¶3§II.6¶3ṣ1A User Product is either

  1. (1) ṣ1.1a consumer product, which means any tangible personal property which is normally used for personal, family, or household purposes, or
  2. (2) ṣ1.2anything designed or sold for incorporation into a dwelling.

§II.6¶3ṣ2In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. §II.6¶3ṣ3For a particular product received by a particular user, normally used refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. §II.6¶3ṣ4A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.

§II.6¶4§II.6¶4ṣ1Installation Information for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. §II.6¶4ṣ2The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.

§II.6¶5§II.6¶5ṣ1If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. §II.6¶5ṣ2But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).

§II.6¶6§II.6¶6ṣ1The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. §II.6¶6ṣ2Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.

§II.6¶7§II.6¶7ṣ1Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.

7. §II.7Additional Terms.

§II.7¶1§II.7¶1ṣ1Additional permissions are terms that supplement the terms of this License by making exceptions from one or more of its conditions. §II.7¶1ṣ2Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. §II.7¶1ṣ3If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.

§II.7¶2§II.7¶2ṣ1When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. §II.7¶2ṣ2(Additional permissions may be written to require their own removal in certain cases when you modify the work.) §II.7¶2ṣ3You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.

§II.7¶3§II.7¶3ṣ1Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:

  1. a) ṣ1.aDisclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
  2. b) ṣ1.bRequiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or
  3. c) ṣ1.cProhibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
  4. d) ṣ1.dLimiting the use for publicity purposes of names of licensors or authors of the material; or
  5. e) ṣ1.eDeclining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
  6. f) ṣ1.fRequiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.

§II.7¶4§II.7¶4ṣ1All other non-permissive additional terms are considered further restrictions within the meaning of section 10. §II.7¶4ṣ2If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. §II.7¶4ṣ3If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.

§II.7¶5§II.7¶5ṣ1If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.

§II.7¶6§II.7¶6ṣ1Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; ṣ1.1the above requirements apply either way.

8. §II.8Termination.

§II.8¶1§II.8¶1ṣ1You may not propagate or modify a covered work except as expressly provided under this License. §II.8¶1ṣ2Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).

§II.8¶2§II.8¶2ṣ1However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated

  1. (a) ṣ1.aprovisionally, unless and until the copyright holder explicitly and finally terminates your license, and
  2. (b) ṣ1.bpermanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.

§II.8¶3§II.8¶3ṣ1Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.

§II.8¶4§II.8¶4ṣ1Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. §II.8¶4ṣ2If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.

9. §II.9Acceptance Not Required for Having Copies.

§II.9¶1§II.9¶1ṣ1You are not required to accept this License in order to receive or run a copy of the Program. §II.9¶1ṣ2Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. §II.9¶1ṣ3However, nothing other than this License grants you permission to propagate or modify any covered work. §II.9¶1ṣ4These actions infringe copyright if you do not accept this License. §II.9¶1ṣ5Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.

10. §II.10Automatic Licensing of Downstream Recipients.

§II.10¶1§II.10¶1ṣ1Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. §II.10¶1ṣ2You are not responsible for enforcing compliance by third parties with this License.

§II.10¶2§II.10¶2ṣ1An entity transaction is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. §II.10¶2ṣ2If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.

§II.10¶3§II.10¶3ṣ1You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. §II.10¶3ṣ2For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.

11. §II.11Patents.

§II.11¶1§II.11¶1ṣ1A contributor is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. §II.11¶1ṣ2The work thus licensed is called the contributor's contributor version.

§II.11¶2§II.11¶2ṣ1A contributor's essential patent claims are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. §II.11¶2ṣ2For purposes of this definition, control includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.

§II.11¶3§II.11¶3ṣ1Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.

§II.11¶4§II.11¶4ṣ1In the following three paragraphs, a patent license is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). §II.11¶4ṣ2To grant such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.

§II.11¶5§II.11¶5ṣ1If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either

  1. (1) ṣ1.1cause the Corresponding Source to be so available, or
  2. (2) ṣ1.2arrange to deprive yourself of the benefit of the patent license for this particular work, or
  3. (3) ṣ1.3arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients.

§II.11¶5ṣ2Knowingly relying means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.

§II.11¶6§II.11¶6ṣ1If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.

§II.11¶7§II.11¶7ṣ1A patent license is discriminatory if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. §II.11¶7ṣ2You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license

  1. (a) ṣ2.ain connection with copies of the covered work conveyed by you (or copies made from those copies), or
  2. (b) ṣ2.bprimarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.

§II.11¶8§II.11¶8ṣ1Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.

12. §II.12No Surrender of Others' Freedom.

§II.12¶1§II.12¶1ṣ1If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. §II.12¶1ṣ2If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. §II.12¶1ṣ3For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.

13. §II.13Remote Network Interaction; Use with the GNU General Public License.

§II.13¶1§II.13¶1ṣ1Notwithstanding any other provision of this License, if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source of your version by providing access to the Corresponding Source from a network server at no charge, through some standard or customary means of facilitating copying of software. §II.13¶1ṣ2This Corresponding Source shall include the Corresponding Source for any work covered by version 3 of the GNU General Public License that is incorporated pursuant to the following paragraph.

§II.13¶2§II.13¶2ṣ1Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU General Public License into a single combined work, and to convey the resulting work. §II.13¶2ṣ2The terms of this License will continue to apply to the part which is the covered work, but the work with which it is combined will remain governed by version 3 of the GNU General Public License.

14. §II.14Revised Versions of this License.

§II.14¶1§II.14¶1ṣ1The Free Software Foundation may publish revised and/or new versions of the GNU Affero General Public License from time to time. §II.14¶1ṣ2Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.

§II.14¶2§II.14¶2ṣ1Each version is given a distinguishing version number. §II.14¶2ṣ2If the Program specifies that a certain numbered version of the GNU Affero General Public License or any later version applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. §II.14¶2ṣ3If the Program does not specify a version number of the GNU Affero General Public License, you may choose any version ever published by the Free Software Foundation.

§II.14¶3§II.14¶3ṣ1If the Program specifies that a proxy can decide which future versions of the GNU Affero General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.


§II.14¶4§II.14¶4ṣ1Later license versions may give you additional or different permissions. §II.14¶4ṣ2However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.

§II.17¶1§II.17¶1ṣ1If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.


§IIIHow to Apply These Terms to Your New Programs

§III¶1§III¶1ṣ1If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.

§III¶2§III¶2ṣ1To do so, attach the following notices to the program. §III¶2ṣ2It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; ṣ2.1and each file should have at least the copyright line and a pointer to where the full notice is found.

<§III¶3§III¶3ṣ1one line to give the program's name and a brief idea of what it does.>
§III¶3ṣ2Copyright (C) <year> <name of author>

§III¶4§III¶4ṣ1This program is free software: ṣ1.1you can redistribute it and/or modify it under the terms of the GNU Affero General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.

§III¶5§III¶5ṣ1This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; ṣ1.1without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. §III¶5ṣ2See the GNU Affero General Public License for more details.

§III¶6§III¶6ṣ1You should have received a copy of the GNU Affero General Public License along with this program. §III¶6ṣ2If not, see <>.

§III¶7§III¶7ṣ1Also add information on how to contact you by electronic and paper mail.

§III¶8§III¶8ṣ1If your software can interact with users remotely through a computer network, you should also make sure that it provides a way for users to get its source. §III¶8ṣ2For example, if your program is a web application, its interface could display a Source link that leads users to an archive of the code. §III¶8ṣ3There are many ways you could offer source, and different solutions will be better for different programs; ṣ3.1see section 13 for the specific requirements.

§III¶9§III¶9ṣ1You should also get your employer (if you work as a programmer) or school, if any, to sign a copyright disclaimer for the program, if necessary. §III¶9ṣ2For more information on this, and how to apply and follow the GNU AGPL, see <>.
