Creating Local-First Collaboration Software with Automerge
summary
Local-first collaboration uses CRDTs to keep the primary copy on each device and syncs in background; Automerge is an open-source Rust library compiled to WebAssembly with JS/Swift/Java bindings, a compressed binary format and a new sync protocol (v2 → v2.1 adds rich text), and a companion Automerge repo for storage/networking. It automatically merges concurrent edits (examples: to-do list merges, character- and span-level text merges via Peritext), only needing manual UI when the same key is set differently; production-ready with performance gains and commercial support.
