Couchbase is a privately held database technology company formed in 2011, with headquarters in Santa Clara, California, USA. It originated from combining two open-source initiatives. Couchbase develops and maintains an enterprise-class, scalable, distributed NoSQL database platform supporting hybrid, multi-cloud, and edge deployments. Its offerings include a memory-first masterless database, SQL-based querying, and advanced analytics, with recent expansion into fully managed database-as-a-service models, notably Couchbase Cloud.
