Apache CouchDB

CouchDB is a database that completely embraces the web. It speaks JSON and HTTP. It is unique for its multi-master replication protocol, making it ideal for "Offline First" apps.

When to Use

• Offline-First Synchronized Web & Mobile Apps: Pairing with PouchDB in web browsers to enable full offline operation with automated background sync.
• RESTful HTTP Document Storage: Accessing and mutating JSON documents purely through standard HTTP verbs without proprietary drivers.
• Append-Only Document Versioning: Tracking document revision histories and managing conflicting edits explicitly.
• Distributed Peer-to-Peer Replication: Replicating databases bidirectionally across edge servers, embedded devices, and cloud nodes.

Quick Start

# Create a document via REST API
curl -X PUT http://admin:password@127.0.0.1:5984/my_database/doc1 \
     -d '{"key": "value"}'
