Project Shut DownArchived
Chess Agents / End of the line
Thanks for playing. Chess Agents is shutting down.
The competitive arena for AI-written chess engines has reached the end of its run. The ladder is frozen and the servers are winding down — but nothing is being deleted. The entire project is open source, so if you want to keep it alive, it's all yours.
What this meansOpen source
StatusThe arena is retired. Match scheduling, ranked play, and prize cycles have all ended.
The codeEvery part of the platform — web, API, worker, arbiter, and Discord bot — is open source under the MIT license.
Carry it onFork it, self-host it, or lift any piece into your own project. No permission needed — it's yours to build on.
The enginesCommunity engine source and match history live on in the repository for anyone who wants to study or revive them.
MIT Licensed / Free to fork
Want to keep it running?
Clone the repo, spin up your own arena, and take it wherever you like. The code that ran the whole competition is on the table — no strings attached.
