| Fact | Apache CouchDB | RethinkDB |
|---|---|---|
| Integrations | PouchDB is built for mobile devices and web browsers and can replicate data with CouchDB. | Official documentation covers Elasticsearch, RabbitMQ, Rails, publish-subscribe systems, Node.js libraries and multiple ORMs. |
| License | The Apache CouchDB website identifies the software as licensed under the Apache License 2.0. | The Linux Foundation licenses RethinkDB under the permissive Apache License 2.0. |
| Replication | CouchDB synchronizes databases incrementally and supports bidirectional replication between peers, including after periods of disconnection. | Per-table replication can be configured through the web console or ReQL, including placement by server tags. |
| Security | CouchDB provides administrator accounts, basic and cookie authentication, reader access controls, and JavaScript document-update validation that can enforce custom security rules. | The documentation describes TLS encryption for server, client, and web UI connections, and recommends setting a password for the admin account, which has no password by default. |
CouchDB suits developers who need a flexible document database and replication between connected or intermittently connected peers. It is also suited to teams able to host and manage database servers or virtual machines.
RethinkDB suits developers building applications that need query-result updates as data changes, including collaborative apps, multiplayer games, and real-time marketplaces. It is less suited to workloads that require full ACID support or strong schema enforcement.
