An online coding platform

Ancient Brain is an online coding and hosting platform, for all skill levels.
See About and List of features.


Coders: Make 3D worlds and share them with friends. Clone and edit other people's worlds. Make touch mobile games. Embed your worlds on other sites.
Teachers: Run programming practicals in 3D or 2D or text, with many features designed for teachers. Safely edit and run student code.
Researchers: Upload problems, tender for solutions, test and rank them. Make hybrid AI systems from the code of multiple authors.
Gamers: Play the endless game worlds the coders make. Come and browse an ever-growing archive of games.
Learners: Clone other people's worlds and change one or two lines. What's the worst that could happen?
How to code
You can run the games and "worlds" by clicking on them. But this is also a coding site, where you can code your own games and worlds. You can use this site to learn to code. Or show off your creations if you are an experienced coder.
Click below to learn how to code. There is a choice of "libraries" that you can use: Skip the intro, let us decide the library, and go straight to the starter tutorial:
