What makes Couchbase Server different?
Built as an original multi-purpose NoSQL database, Couchbase Server delivers unparalleled performance at any scale across any cloud. With its memory-first architecture, latency is measured in milliseconds. And with a multi-model JSON document foundation, geo-distributed deployments, workload isolation, and high-density storage, Couchbase is redefining database economics for scalable, mission-critical applications. To round off the solution, Couchbase has the most comprehensive SQL-compatible query language (SQL++) and dynamic schema structures, making it easy to migrate from RDBMS-backed applications.
Enterprises choose Couchbase for its speed, NoSQL versatility, and the ease of SQL++
Fast
The first reason customers choose Couchbase is performance due to its memory-first design and caching architecture.
Affordable
Couchbase does more work for your money due to its scalable, tunable-workload design that optimizes resources as your application grows.
Versatile
The Couchbase powers feature-rich applications because it handles many data access patterns at once without creating architectural complexity.
Easy as SQL
Developers can pick from a dozen SDKs and write SQL++ queries, including JOINs and distributed ACID transactions.
Server key capabilities
Couchbase is a distributed, transactional, multimodel database for AI-powered applications. It does the work of multiple purpose-built databases. It caches data for speed, supports SQL for JSON. and scales linearly. It replicates and synchronizes to mobile apps, and helps simplify data architectures without sacrificing application features.
Queries
SQL++ gives application developers an easy, expressive language for querying, transacting, and manipulating JSON data.
Distributed, multi-document ACID transactions
When transactional guarantees are required, Couchbase holds the patent for distributed ACID transactions for JSON.
Eventing
Couchbase eventing enables user-defined functions in JavaScript or Python to fire in real-time when data changes happen.
Analytics
It's no longer impossible to perform analytics on active application data. You just need a SQL++ analytics engine with workload isolation.
Active-active global replication
Ensure high availability everywhere with global cross data center replication (XDCR) that scales across clouds and locations.
Multi-dimensional scaling (MDS)
Every application scales differently, and so does Couchbase. It is the only database platform that can isolate and scale database services within a cluster independently.
Enterprise-grade security
Compliance and security are fundamental requirements. Protect your data on the wire and in the cloud. Secure your organization with built-in auditing, role-based access control, and encrypted communications.
Full-text search
Better user experiences result from smarter, richer applications. Add text and geo-location search to your apps.
Fast: Unparalleled performance at scale
Deliver consistent, fast experiences at scale, powered by caching and our memory-first architecture. High-performance indexes, flex indexes, and index partitioning underpin exceptional query performance even with complex joins, predicates, and aggregations. And, with efficient, high-density key-value storage that holds terabytes per node, Couchbase significantly reduces the complexity of your clusters and the costs of your deployment.

Versatility of JSON : Unmatched agility and flexibility
Support rapidly changing application requirements with the flexibility of JSON. It can support multiple data access patterns at once, including programmatic key-value, SQL++ query, time-series arrays, vector arrays, graph relationships, metadata, analytics, and text or geographic search. This enables robust functionality within the application without creating unnecessary complexity in the data architecture.
