Automerge: A new foundation for collaboration software
summary
Automerge is an open-source library that gives applications a shared JSON-like CRDT which automatically merges concurrent edits, preserves all updates and guarantees deterministic convergence. JavaScript and a faster Rust backend compiled to Rust WebAssembly expose the same API; changes serialize to compact byte arrays and a snapshot compaction compresses a 360k-keystroke edit log from about 36 MB → 300 KB while keeping full history. It handles real-time and offline syncing, keeps concurrent same-field assignments as multiple values for app-level resolution, and is already used (e.g., Washington Post editorial workflow).
