Apache CouchDB lets you access your data where you need it. The Couch Replication Protocol is implemented in a variety of projects and products that span every imaginable computing environment from globally distributed server-clusters, over mobile phones to web browsers.

Store your data safely, on your own servers, or with any leading cloud provider. Your web- and native applications love CouchDB, because it speaks JSON natively and supports binary data for all your data storage needs.

The Couch Replication Protocol lets your data flow seamlessly between server clusters to mobile phones and web browsers, enabling a compelling offline-first user-experience while maintaining high performance and strong reliability. CouchDB comes with a developer-friendly query language, and optionally MapReduce for simple, efficient, and comprehensive data retrieval.

CouchDB is a terrific single-node database that works just like any other database behind an application server of your choice.CouchDB is also a clustered database that allows you to run a single logical database server on any number of servers or VMs. A CouchDB cluster improves on the single-node setup with higher capacity and high-availability without changing any APIs.
