It's a split decision.
Choose Apache CouchDB for a free, self-hosted JSON database where HTTP access and offline-first replication are the main requirements. Choose Couchbase when you need a broader managed or hybrid platform with search, caching, analytics, and AI services. CouchDB's paid pricing is not published; Couchbase's pricing page lists a free tier and paid Capella plans from $0.15 per node per hour. Compare deployment needs and node counts, not a monthly seat price.

02Pricing compared
CouchDB is free to download and self-host, but its monthly and annual prices are not published. That makes the software price clear and the total operating cost impossible to compare from the published pricing data. Couchbase has a free Capella tier with 1 node and 8GB. Paid Capella starts at $0.15 per node per hour for Basic, $0.35 for Developer Pro and $0.49 for Enterprise; these are hourly node rates, not monthly totals. Couchbase Server Enterprise is listed from $0.66 per node per hour through cloud marketplaces. The bill depends on node count and runtime, while annual prices are not published. Capella backup and storage charges can add to the bill, and data transfer fees vary. Compare required deployment and node count, not a headline monthly price.
03Features and depth
CouchDB focuses on JSON data, HTTP access and replication. Its Couch Replication Protocol syncs data across servers, mobile devices and browsers, including applications that need to work offline or across difficult networks. You can run a single node or cluster; each node uses an append-only storage structure, and MapReduce is an optional query method.
Couchbase is positioned as a broader operational data platform. Its listed capabilities combine storage, search, caching, analytics and AI, with hybrid deployment across cloud and data centers and support for mobile and edge use. The homepage also describes active-active replication across regions and real-time analysis of operational data without warehouses or overnight ETL. Couchbase Mobile is a separate offering with custom pricing; its listed features include Couchbase Lite, Sync Gateway, peer-to-peer syncing and vector search. The practical distinction is scope: CouchDB centers on JSON and replication, while Couchbase groups more data services under one platform.
04Ease of use and learning curve
The sources do not provide setup steps or a measured learning-curve comparison, so we would not call either product easier based on this material alone. CouchDB gives you a straightforward deployment choice—one node or a cluster—and an HTTP/JSON interface. Because it is self-hosted, your team must choose and manage its deployment rather than buy a published CouchDB hosting plan.
Couchbase Capella offers managed tiers, but picking one means weighing node minimums, hourly rates, backup intervals, availability zones and support. The free tier is limited to 1 node and 8GB. For a switch, map the needed services and deployment first; Couchbase's wider feature set may also mean a more involved plan comparison.
Questions people ask
What does Couchbase software do?
Couchbase is an operational data platform for storing, searching, caching, analyzing and using data for AI. Its listed deployment options include cloud, customer data centers, mobile and edge environments. The platform also describes active-active replication and real-time operational insights.
Is Apache CouchDB free?
CouchDB is free to download and self-host, according to the published pricing information. Monthly and annual billing prices are not published, and the information does not give a hosted-plan price. Couchbase, by contrast, lists a free Capella tier and paid hourly node rates.
How are Couchbase Capella plans priced?
Capella lists prices per node per hour, not as monthly totals. Basic starts at $0.15, Developer Pro at $0.35 and Enterprise at $0.49 per node per hour. Node minimums and included services differ by plan, and annual prices are not published.
What are the key differences between Apache CouchDB and MongoDB?
The published product information covers CouchDB and Couchbase, not MongoDB, so it does not support a detailed comparison. It describes CouchDB as a JSON database with an HTTP API and replication. For a fair CouchDB–MongoDB comparison, check MongoDB’s current features and pricing separately.
