Apache Foundation open-source document database with bidirectional replication and HTTP-native REST API; canonical database for offline-first mobile apps using JSON documents with MVCC and JavaScript MapReduce.
Apache CouchDB is a free, open-source document-oriented NoSQL database — managed by the Apache Software Foundation — storing data as JSON documents, using HTTP/REST as its native API, and employing JavaScript for MapReduce views and query logic. Originally developed by Damien Katz and released in 2005, CouchDB's distinctive architecture centers on multi-master replication with bidirectional sync capability: multiple CouchDB nodes (including mobile devices) replicate documents with each other bidirectionally, automatically resolving conflicts using Multi-Version Concurrency Control (MVCC) — making CouchDB the canonical database for offline-capable applications and distributed systems requiring eventual consistency.
