A high-performance Rust CRDT library for concurrent text editing, enabling multiple users to edit shared documents in a P2P network without a central server. It is optimized for speed and interoperable with positional updates via operational transform, with WASM builds for Node.js and browsers.

Use cases

• build a collaborative text editor with real-time multi-user editing
• sync text documents between peers without a central server
• add CRDT-based offline-first editing to an app
• integrate collaborative editing into a browser or Node.js app via WASM
• bridge CRDT updates with operational-transform-based clients
• benchmark or study high-performance CRDT implementations

When to choose

• you need extremely fast CRDT performance for plain text editing
• you want serverless P2P collaborative text editing
• you need a Rust CRDT with WASM bindings for web apps
• you need interoperability with operational-transform-based peers

When to avoid

• you need CRDTs for rich text or structured JSON data (only plain text is supported)
• you need a stable, production-hardened API (the project is WIP and the published crate is outdated)
• you need a license other than ISC or strict licensing guarantees (license metadata is missing on the repo)
