The future of software will consist of thousands of autonomous AI agents operating simultaneously. Sequential execution is fundamentally incompatible with that future.

Details
Any developer, anywhere. Enter solo and we'll help you find teammates, or bring your own team. Team size limits announced soon.
A working system where several agents run at the same time — sharing state and coordinating with each other, rather than handing off in a fixed sequence. There's one open brief, not separate tracks: what you build is up to you, as long as concurrency is the point. You submit a repo and a short demo.
No. Mozaik is JigJoy's open-source TypeScript runtime for concurrent agents, and everyone who applies gets the docs, a starter template, and a short primer before kickoff.
The build weekend is 5–6 September 2026. A livestream introduction to Mozaik runs on 4 September, submissions close on the evening of the 6th, and winners are announced on 13 September. Exact times and timezone announced soon.
Judging criteria and the panel are announced soon. Expect weight on genuine use of concurrency — agents that actually run together, not a sequential pipeline in disguise.
Nothing. It's free to enter and fully online.
