Profile
Apache CouchDB is an open-source document database that syncs data across devices and servers using a built-in replication engine.
Apache CouchDB is an open-source, NoSQL document database that stores data in JSON and uses an HTTP API for access. It was created in 2005 by Damien Katz and became an Apache Software Foundation project in 2008. CouchDB's core differentiator is its multi-primary replication, which enables offline-first and local-first application architectures.
The project is maintained by a volunteer community and has no single corporate parent. As of mid-2025, the CouchDB team regularly ships updates, with version 3.5.2 released in May 2026. A 2025 user survey found that over 60% of respondents upgraded to 3.4.2 within three months of release, and replication, the changes feed, the HTTP API, and clustering were cited as the most-loved features.
The project has no disclosed revenue, funding, or headcount—it is an Apache project, not a company. CouchDB competes with MongoDB, Amazon DynamoDB, and Google Firestore, but occupies a distinct niche due to its offline-first sync capabilities. The project's community has remained stable for roughly 15 years, and users consistently praise its reliability, with one respondent noting 'I’ve had 0 production issues in 15 years.' CouchDB is not to be confused with Couchbase, a separate, publicly traded company (NASDAQ: BASE) that reported $57.6 million in revenue for Q2 fiscal 2026 (ended July 31, 2025) and had $260.5 million in annual recurring revenue. Couchbase is acquiring itself in a transaction with Haveli Investments, announced in 2025.
Who buys this
- Developers building offline-first mobile and web applications
- Organizations requiring reliable, multi-master replication across distributed systems
- Teams that prefer an HTTP/JSON API over SQL or proprietary protocols
- Enterprises and institutions that value open-source governance and long-term stability
Strengths and what to watch
Strengths
- Multi-primary replication is a core feature that enables offline-first and local-first architectures, with PouchDB being the most popular client-side replication library (82.4% of survey respondents use it).
- HTTP/JSON API allows direct interaction without client libraries, reducing dependency complexity and making it accessible from any programming language.
- Proven reliability over long periods: users report zero production issues over 15 years, and the project maintains backward compatibility across major upgrades.
Watch for
- CouchDB is often confused with Couchbase, a separate for-profit company. Couchbase's financial results and acquisition news can create market confusion about CouchDB's status and roadmap.
- The project has no dedicated funding or paid staff, relying entirely on volunteer contributors. This can lead to slower response times for security patches or feature requests compared to commercially backed databases.
- Adoption is niche and concentrated in offline-first and local-first use cases. Broader enterprise adoption is limited compared to MongoDB or PostgreSQL, which may reduce ecosystem growth and third-party tooling.

Frequently Asked Questions
What is Apache CouchDB and what is it used for?
Apache CouchDB is an open-source NoSQL document database that stores data in JSON format and provides an HTTP API for access. It is commonly used for offline-first and local-first applications due to its built-in multi-primary replication engine that syncs data across devices and servers.
How does CouchDB replication work for offline-first apps?
CouchDB uses multi-primary replication, allowing any node to accept writes and sync changes with other nodes. This enables offline-first architectures where apps work without a constant internet connection. PouchDB, a client-side library, is used by 82.4% of survey respondents to replicate data locally in browsers.
What is the difference between CouchDB and Couchbase?
CouchDB is an open-source Apache project maintained by volunteers with no corporate parent. Couchbase is a separate, publicly traded company (NASDAQ: BASE) that reported $57.6 million in revenue for Q2 fiscal 2026. They are not the same product, though often confused. CouchDB focuses on offline-first replication.
Is CouchDB reliable for production use?
Yes, CouchDB has a strong reputation for reliability. Users report zero production issues over 15 years, and the project maintains backward compatibility across major upgrades. The 2024 user survey highlighted replication, the changes feed, and the HTTP API as most-loved features, with over 60% upgrading to 3.4.2 quickly.
How does CouchDB compare to MongoDB or Amazon DynamoDB?
CouchDB competes with MongoDB, DynamoDB, and Google Firestore but occupies a distinct niche due to its offline-first sync capabilities. Unlike MongoDB, CouchDB uses an HTTP/JSON API natively and supports multi-master replication. It is ideal for distributed systems requiring reliable sync without a constant connection.
What are the limitations of using Apache CouchDB?
CouchDB has no dedicated funding or paid staff, relying on volunteer contributors, which can slow security patches or feature requests. Its adoption is niche, focused on offline-first use cases, limiting ecosystem growth compared to MongoDB or PostgreSQL. It is also often confused with Couchbase, causing market confusion.
