PartyKit
MIT realtime rooms on Cloudflare Durable Objects; pay CF Workers only
Comms / Realtime · OSS/MIT · 1.3k
What's Good
MIT (Cloudflare-owned). PartyServer model on Workers + Durable Objects. TypeScript rooms, Yjs-friendly patterns, partykit deploy to your CF account. No PartyKit seat tax — Workers free tier covers small traffic.
The Catch
Vs Liveblocks/Yjs+Hocuspocus: room primitive on CF, not prebuilt comments/inbox SaaS. You pay Cloudflare Workers/DO usage at scale. Auth, persistence, and CRDT choice are yours. Post-acquisition roadmap rides CF.
Verdict
MIT CF realtime rooms. Free software; hosting is Workers/DO billing.
