Whatever Origin (whateverorigin.org)

That's what i love about open source. You have a problem, solve it and others can benefit from it and even extend your solution.

Great work

The GH issues hint this is not maintained? The site itself seems to be working, though.

Although since recently I have been using https://github.com/technoboy10/crossorigin.me without any downtimes or ssl issues. (I am not related to any of the two projects in any way, though.)
