Is there any way to compile code ( C/ C++ ) with in browser?

Question

This question may sound crazy.Is there anything browser based compiler out there ?

Answer 1

Native Client is a sandbox for running compiled C and C++ code in the browser efficiently. You can explore this.

Answer 2

It is possible to run native binaries in a browser using an x86 emulator in JavaScript, so a C compiler could run in a browser in this way.

It is also possible to write a "self-hosting" C-to-WebAssembly compiler that runs in a browser, such as emception.
