### What we like

Makes it easy to build sophisticated text editing features like undo, real-time collaboration, history tracking & versioning, and conflict resolution of multiple edits. Available as a Rust library as well as a JS package which uses WASM. Allows offline editing.

### Tradeoffs

API is not yet stable so they don’t recommend using it in production.
