This has all three (GNU, LLVM and Microsoft): http://rextester.com/runcode

[shadder]

www.codepad.org is a great online compiler

If you are planning to do a lot of online coding I would recommend.

https://koding.com/Home
Free online VM with root access, enough said ;p.

Otherwise if you just want to compile some code from sites/forums or test out little things here and there I would just stick to ideone or something like that.
