Scripts like ideone.com and codepad.org

Are 开发者_如何学运维there any auto compiling scripts like the ones used at ideone.com and codepad.org available?

(preferably open source, and which execute the code in a safe environment.)

I don't think that they have special "autocompiling scripts". They could just be using normal compilers under a virtual machine for safety.

Or they could have developed something custom (Like Google app engine)

Update:

Apparently they are using normal compiler packages by Gentoo.

Why not to use Ideone API?
