An online coding platform

Ancient Brain is an online coding and hosting platform for everyone.
See Introduction and List of features.


Coders: Make 3D worlds and share them with friends. Clone and edit other people's worlds. Make multi-user games and environments. Make touch mobile games. Upload your own images, music and 3D models. Embed your worlds on other sites.
Teachers: Run courses in coding and coding for kids and AI coding. Run programming practicals in 3D graphics or 2D graphics or text, with many features designed for teachers. Safely edit and run student code.
Learners: Do courses in coding and coding for kids and AI coding. Clone other people's worlds and change one or two lines. What's the worst that could happen?
Gamers: Play the endless game worlds the coders make. Come and browse an ever-growing archive of games.
Researchers: Upload problems, tender for solutions, test and rank them. Make hybrid AI systems from the code of multiple authors.
Getting started
You can "run" any of the 9,329 programs or "Worlds" by clicking on them. But this is also a coding site, where you can code your own Worlds. You can use this site to learn to code. Or show off your creations if you are an experienced coder.
Basically you can read more about how to get started running Worlds and coding: Or you can leap straight into coding with our starter tutorial:
Programming course

Ancient Brain has a course in how to program from scratch.

Starter Worlds for Three.js

These are the main "Starter Worlds" that use the Three.js library (which tends to give the most advanced graphics).

You can Clone and Edit all of these and change their code. Look for a section at the top called the "Tweaker's Box". This contains the easiest things to change.

Call for partners!
Ancient Brain is looking for a partner to co-write a JavaScript coding book for schools, to be used worldwide. This would be a course for students in learning to code from scratch. The book and course will be integrated into the Ancient Brain site. This is an opportunity for someone looking to develop a course and textbook to partner with a site to promote it. Read more.
