Both GPL and AGPL are open software liceneses which create an obligation on people who “publish” the binary. (“Publish” is a term of art here.) The difference is when the obligation is triggered: In the case of AGPL it adds the obligation when a modified version is used over a network to provide the source code of the modified version running there to the users of that server. Therefore, the mere public use of a modified version, on a publicly accessible server, gives the public access to the source code of the modified version of the AGPL licensed software.
