Everything's better with friends
summary
Claim: multiplayer apps become practical for small teams because edge compute plus CRDTs make state local and consistent. Uses Cloudflare durable objects and a deployed platform called party kit with GitHub preview deploys and CLI tooling. Demo shows a tldraw-backed collaborative canvas with an eight-line backend, supports CRDT libs like Yjs or Automerge, runs on Cloudflare’s ~250 cities and 10,000 PoPs, handles ~40–50 concurrent users per room today, and is open source and deployable now.
