Automerge

A pure-CRDT library for building collaborative applications with automatic conflict resolution and change tracking.

Overview

Automerge provides a JavaScript library for creating documents that can be edited concurrently by multiple users and merged automatically. Unlike Yjs, it focuses on a JSON-like document model with strong opinions on data types and change tracking. It is designed to be simple to use with standard JavaScript objects and integrates well with reactive UI libraries like React.
