Hypermerge is a Node.js library for building peer-to-peer collaborative applications without server infrastructure, combining the Automerge CRDT with hypercore distributed append-only logs. It is now deprecated and unmaintained, with automerge-repo recommended as its replacement.
Use cases
- build p2p collaborative apps without a server
- offline-first document sync between peers
- conflict-free replicated data in Node.js
- serverless real-time collaboration
- replicate CRDT documents over a peer swarm
- build local-first chat or shared-state apps
When to choose
- you need a legacy dependency for an existing hypermerge-based project
- studying how CRDTs and hypercore can be combined for p2p sync
When to avoid
- starting any new project - it is deprecated and unmaintained
- you need security or privacy guarantees - none were audited
- you need fast synchronization - it is slow with many documents
- you want current Automerge features - use automerge-repo instead
