Hey, great feedback. I'm currently re-doing the landing page as the project has expanded quite a bit (including native annotations/comments, presence, inter-instance collaboration/sharing, Yjs based real-time collaboration for agents and humans, etc).

Currently this works using Cloudflare Workers (and Durable Objects). This provides your agents with trivial tools to make realtime multi-player artifacts. Some demos include (all made by DeepSeek v4.1 Flash in ~5-10m each:

- Real-time tic-ta-toe: https://demo.open-artifacts.com/a/kA5P1UTCZ9jwRSAx - Chess: https://demo.open-artifacts.com/a/ErF1KapC2paDnmgs - Mini version of r/place (pixel canvas): https://demo.open-artifacts.com/a/xsDmeifD7bX7NeSJ - Live poll: https://demo.open-artifacts.com/a/PY6AbssBQg4epqgk

The full list of demos is here: https://demo.open-artifacts.com/

I'll be opening sign-ups for a hosted version in the coming days. All feedback welcome. Actively trying to make it better.
