• Support both Linux and Windows, 32-bit and 64-bit.

• Locally run C/C++ code in sophisticated libsandbox environment to prevent attacks (e.g. rebooting system, accessing files/network, consuming/occupying system resources). (Linux only)

• Remotely run C/C++, Java, C#, Python, php, schema and other more than 40 languages in http://ideone.com. It is safe and free. See http://ideone.com/faq for full list of supported languages.

• Support multiply test cases.

• Compile only mode.
