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.
A semantic data platform MCP server that composes multiple data tools with bidirectional cross-injection - tool responses automatically include critical context from other services.
A fast JSONLogic rules engine: one Rust core with official bindings for Node.js, Python, Go, Java, .NET, PHP, and the browser (WASM), plus a React visual debugger.
