Couchbase Server, originally known as Membase, is an open-source, distributed multi-model NoSQL document-oriented database software package that is optimized for interactive applications.
Couchbase provides an enterprise-class, multicloud to edge database that offers the robust capabilities required for business-critical applications on a highly scalable and available platform.
Couchbase was founded in 2009. The company is headquartered in Santa Clara, California, with offices in Manchester, London, Paris and Bangalore.
Couchbase is built on open standards, combining the best of NoSQL with the power and familiarity of SQL, to simplify the transition from mainframe and relational databases.
Couchbase Server is designed to provide easy-to-scale key-value or JSON document access with low latency and high sustained throughput. It is designed to be clustered from a single machine to very large-scale deployments spanning many machines. A version originally called Couchbase Lite was later marketed as Couchbase Mobile combined with other software.
Couchbase Server provided client protocol compatibility with memcached, but added disk persistence, data replication, live cluster reconfiguration, rebalancing and multitenancy with data partitioning. Couchbase has supported software developers' kits for the programming languages .Net, PHP, Ruby, Python, C, Node.js, Java, and Go.
Couchbase is backed by Sorenson Capital, Accel Partners, Adams Street Partners, Ignition Partners, Mayfield Fund, North Bridge Venture Partners and others. The company raised $105M in a Series G round on May 21, 2020. This brings Couchbase's total funding to $251M to date.
