The GNU Affero General Public License is a free, copyleft license published by the Free Software Foundation in November 2007, and based on the GNU General Public License, version 3 and the Affero General Public License.

The Free Software Foundation has recommended that the GNU AGPLv3 be considered for any software that will commonly be run over a network.[2] The Open Source Initiative approved the GNU AGPLv3[3] as an open source license in March 2008 after the company Funambol submitted it for consideration.[6]

Compatibility with the GPL[edit]

GNU AGPLv3 and GPLv3 licenses each include clauses (in section 13 of each license) that together achieve a form of mutual compatibility for the two licenses. These clauses explicitly allow the "conveying" of a work formed by linking code licensed under the one license against code licensed under the other license,[7] despite the licenses otherwise not allowing relicensing under the terms of each other.[2] In this way, the copyleft of each license is relaxed to allow distributing such combinations.[2]

Examples of applications under GNU AGPL[edit]

Stet was the first software system known to be released under the GNU AGPL, on November 21, 2007,[8] and is the only known program to be used mainly for the production of its own license.

Flask developer Armin Ronacher noted in 2013 that the GNU AGPL is a "terrible success" as "vehicle for dual commercial licensing" and gave Humhub, MongoDB, OpenERP, RethinkDB, Shinken, Slic3r, SugarCRM, and WURFL as examples.[9]

Some of the best-known examples of GNU AGPL licensed software include:

  • the NoSQL database BerkeleyDB
  • the distributed social networking service Diaspora
  • the application development and maintenance software Launchpad
  • the cross-platform document-oriented database MongoDB
  • the enterprise resource planning platform Odoo
  • the file hosting services ownCloud
  • the integrated development environment for the statistics language R, RStudio
  • the PDF producer iText

The AGPLv3 was a terrible success, especially among the startup community that found the perfect base license to make dual licensing with a commercial license feasible. MongoDB, RethinkDB, OpenERP, SugarCRM as well as WURFL all now utilize the AGPLv3 as a vehicle for dual commercial licensing. The AGPLv3 makes that generally easy to accomplish as the original copyright author has the rights to make a commercial license possible but nobody who receives the sourcecode itself through the APLv3 inherits that right. I am not sure if that was the intended use of the license, but that's at least what it's definitely being used for now.
