repl.it is an online REPL that supports 15+ languages, from Python to QBasic, using language interpreters written in JavaScript or compiled to JavaScript using Emscripten (http://emscripten.org/).

This project grew from @amasad and me wanting a quick way to try out little snippets of code while learning a new language or when away from our work machines.

We opted to have all the execution client-side to provide a smooth experience where you don't have to wait for the server to respond to every command. Technically you don't even need an internet connection once it's cached. You can also save your REPL session and resume from another machine, or share it with other people. We have beta support for mobile devices, so you can REPL from your Android or iPhone, though Ruby and Python are still not supported on iOS.

The code is open sourced under the MIT license and available from GitHub (https://github.com/replit).

All feedback greatly appreciated!
