Ports to other languages

Yjs has been ported to other languages.

GitHub - yjs/ycs: A compatible .Net implementation of the Yjs CRDT framework.GitHub

C# port of Yjs

ygo

A pure Go port of Yjs. Wire-compatible with the JavaScript reference (V1/V2 update codecs, awareness, snapshot), with the full CRDT engine (YArray, YMap, YText with rich-text formatting and embeds, YXml*), built-in WebSocket and HTTP sync transports, and an UndoManager. In production at Re:Earth.

GitHub - reearth/ygo: A pure-Go, production-grade implementation of Yjs. Runs real collaborative apps: a horizontally-scaling, Hocuspocus-compatible websocket server with versioned persistence and compaction. Hardened by differential fuzzing and a byte-level conformance suite. Also embeddable on iOS/Android via gomobile.GitHub

Go port of Yjs

ygo (Deln0r/ygo)

Pure-Go port of Yjs, byte-for-byte wire-compatible with the JavaScript reference in both V1 and V2 update formats, verified bidirectionally by a 114-scenario cross-language fixture suite against yjs@13.6.x. Hocuspocus-compatible WebSocket server, SQLite persistence, UndoManager, iOS/Android via gomobile, no CGO.

GitHub - Deln0r/ygo: Officially listed, pure-Go port of the Yjs CRDT, byte-for-byte V1/V2 wire-compatible with yjs@13.6.31 (cross-language fixtures, both directions). UndoManager, snapshots, subdocuments, cursors, GC. yserve: single-binary Hocuspocus-compatible server with SQLite persistence and document versioning. iOS/Android via gomobile. No CGO.GitHub
