When your application needs everything, you choose Couchbase
Most databases can only satisfy one or two fundamental DBMS requirements. Some are feature-rich with multi-model capabilities but aren’t fast or scalable. Some are fast and scalable but have limited features. Some are as easy as SQL, while others are programmatic. Some have a fixed schema, while others offer flexible data structures. Some reside in a single cloud and don’t offer multi- and hybrid-cloud integration. Only a handful can be mobile. And almost none have an expandable architecture from the beginning.

Couchbase is the OG multi-model NoSQL database, and it’s becoming even stronger as it grows
Blazing fast
The "base" in Couchbase comes from Membase, the blazingly fast key/value database based on open source memcached.
Linear scale
The "Couch" in Couchbase stands for Clusters Of Unreliable Commodity Hardware. Couchbase scales linearly to hundreds of nodes.
Amazing versatility
Couchbase can handle many data access patterns at once: key-value, JSON document, search, time series, analytics, eventing, and SQL query.
Easy as SQL
Developers can use over a dozen SDKs and write SQL++ queries, including JOINs and distributed ACID transactions.
Why do we win? What’s the secret? An ingenious architecture
Couchbase tackled the most difficult database problem first: scaling a distributed database. With a scalable, reliable, high-performance foundation, the Couchbase architecture is incredibly clever.
Memory-first architecture
Every database operation is executed in memory and cached for next time.
Auto-partitioning
Data often exceeds the size of a hard drive, so Couchbase built the cluster map.
Resource scaling
MDS enables the data, index, and query services to scale individually.
Replication
Intra- and inter-cluster replication occurs in milliseconds.
Developers love the JSON document format
Developers love using flexible JSON to control data structures. If a schema is needed, scopes and collections organize the documents. They love using SQL++, which includes built-in JOINS, transactions, query plans, UDFs, and cost-based optimization. And they love using AI-powered Capella iQ to write queries.

Couchbase is built for tomorrow’s AI-powered applications
Versatile JSON is perfect for AI because it can hold all types of data, from account personalization information to metadata. It’s the ideal format to support many data access patterns from key-value to SQL++ to full-text search. And generative AI LLMs understand how to create and query JSON documents.

Performance, scale, latency, and mobility are more important than ever
High performance, linear scale, rich data access patterns, global replication, synchronization, and mobility are all foundational requirements of emerging AI applications. Couchbase is the rare platform that seamlessly addresses all of them while providing low costs and high availability anywhere.
