The GNU Affero General Public License or GNU AGPL is a free software license published by the Free Software Foundation. The GNU AGPL is similar to the GNU General Public License, except that it has an additional section to cover use over a computer network. It closes what is commonly known as the Application service provider loophole of the GNU General Public License. The additional section requires that the complete source code be made available to any network user of the AGPLed work, typically a web application. For the legally precise description see the external link at the end of the article.

The Free Software Foundation recommends this license for any software that will commonly be run over the network .

Note that GNU Affero General Public License is not the same legal document as the Affero General Public License, though they are quite similar in intent and effect.
