Ok guys, I've started this page[1]. I am sure that I don't know all useful tools running on our infra, neither all Free instance running on the Web. Please, fill it. I think tools like pkgdb[2] should also be included, but I don't know this project too much.
The fact is that we have many tools running that lots of contributors are not aware of. I hope this page could aggregate things.
