Show HN: Hocuspocus 4 – self-hosted Yjs collaboration backend

Hocuspocus 4 is a self-hosted Yjs collaboration backend that enables real-time collaboration in web editors, and it has been released under the MIT license with significant changes, including being no longer tied to Node. The new version allows running collaboration at the edge and supports multiple platforms such as Bun, Deno, and Cloudflare Workers. Hocuspocus is built on top of Yjs, a CRDT library that handles concurrent edits without conflicts.
