FAQ
Couchbase Mobile vs. Firebase FAQ
Get quick answers to questions about how Couchbase Mobile compares to Firebase.
Does Firebase support offline-first apps?
Firebase offers basic local caching for brief outages but has no embedded database, delta sync, or peer-to-peer sync. It is not designed for true offline-first applications.
Does Couchbase Mobile work without internet?
Yes. Couchbase Mobile stores data locally on-device using an embedded database, syncs bidirectionally when connectivity returns, and supports peer-to-peer sync between devices.
Does Firebase support multicloud deployment?
No. Firebase is hosted exclusively on Google Cloud with no support for AWS, Azure, on premises, or hybrid deployments. Couchbase Mobile runs across all major clouds and on premises.
How does Firebase handle complex queries?
Firebase provides a limited SQL-like query language with no JOIN support. Couchbase Mobile uses SQL++, which supports JOINs, aggregations, and complex queries natively.
Does Firebase support on-device vector search for edge AI?
Firebase does not have on-device vector search. For 100% on-device vector search, developers must pair the platform with a local edge database that supports vector search.
