In the AGPLv3 text -after the END OF TERMS AND CONDITIONS
line- there is this recommendation on How to Apply These Terms to Your New Programs which rather terse and states that there are many ways
to offer source code:
[...] If 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. For example, if your program is a web application, its interface could display a "Source" link that leads users to an archive of the code. There are many ways you could offer source, and different solutions will be better for different programs; see section 13 for the specific requirements. [...]
And the section 13 it points back to does not provide much more guidance:
[...] through some standard or customary means of facilitating copying of software.
So what are actual mechanisms implemented by AGPL-licensed projects for users to get the corresponding source code?
- for a web application with a UI?
- for an application with no UI and only a REST API?
- for a command line application?
- for a library?
