scuttlebutt

Scuttlebutt is an open-source JavaScript library for building peer-to-peer applications with automatically replicated data structures. It enables multiple computers to maintain synchronized copies of shared information without depending on a central database. The library uses gossip-based replication to exchange updates between connected peers. Developers can create custom data models by extending its base replication class. Included implementations demonstrate replicated key-value models and event streams. Its ecosystem also includes collaborative text editing, replicated arrays, and append-only data structures. Optional public-key cryptography helps authenticate updates and verify message origins. Scuttlebutt provides foundational components for decentralized applications, collaborative software, and distributed data synchronization.
