Seamless multi-primary sync, that
scales from Big Data to Mobile,
with an Intuitive HTTP/JSON API
and designed for Reliability.
Data Where You Need It
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.

Single Node Database
CouchDB is a terrific single-node database that works just like any other database
behind an application server of your choice.
Most people start with a single node CouchDB instance. More demanding projects can
seamlessly upgrade to a cluster.
Cluster
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.
HTTP/JSON
CouchDB makes use of the ubiquitous HTTP protocol and JSON data format and is compatible with any software that supports them. CouchDB also works great with external tools like HTTP proxy servers, load balancers.
Offline First Data Sync
CouchDB’s unique Replication Protocol is the foundation for a whole new generation of “Offline First” applications for Mobile applications and other environments with challenging network infrastructures.
Ecosystem
CouchDB is built for servers (from a Raspberry Pi to big cloud installations), while
PouchDB is built for mobile & web-browsers.
They can seamlessly replicate data with each other.
Reliability
CouchDB is serious about data reliability.
Individual nodes use a crash-resistant append-only data structure. A multi-node
CouchDB cluster saves all data redundantly, so it is always available when you need
it.

We’re not just building a database – we’re crafting the CouchDB story. Help us promote CouchDB: plan meetups, make video tutorials, write blog posts.
Website
Got a few suggestions for the very website you’re reading right now? Think the UX, copy, or layout could be better? Welcome! We’d love to hear from you.
Documentation
Docs can be improved indefinitely. If you’ve got a flair for technical writing, help us make the docs clearer, better structured, or even translate them.
Guidance
You can be the first person someone interacts with when they have a question. Giving guidance is a great way to help others while learning CouchDB.
CouchDB Chat
We run community chat channels on Libera.Chat IRC network and Slack. IRC is open and very common, but Slack is more user-friendly.
IRC
We have two IRC channels. #Couchdb for discussions on using CouchDB and #CouchDB-dev for discussions on CouchDB development.
- — #CouchDB
- — #CouchDB-dev
