About

I built Code Royale because my friends and I used to play Clash of Code on CodinGame, but there were a few things we didn't like, so I decided to build our own version. It doesn't need sign-up and supports Python, JavaScript, Go, Java, C, C++, and Rust. The whole project is open source and can be self-hosted.
