Couchbase Lite
Couchbase Lite embeds a database in your app, syncs data from cloud-to-edge and peer-to-peer, and keeps working when the network doesn’t. Support for iOS, Android, Java, .NET, JavaScript, C/C++ and cross-platform frameworks – with SQL, full-text search, and on-device vector search built in. Pair it with Sync Gateway/App Services for cloud-to-edge sync.
What makes Couchbase Lite different?
Couchbase Lite is the only embedded database that gives you local storage, cloud-to-device and peer-to-peer sync, SQL queries, and on-device vector search in one scalable platform. Build resilient apps that always work – even without internet.
Build fast, secure, and reliable edge AI apps
Local speed
Reads and writes hit the embedded database at memory speed – no network round-trip, no stalled UI.
Always available
Apps keep reading and writing when the network fails. Sync catches up automatically when connectivity returns.
AI on-device
On-device vector search powers semantic queries and RAG with no internet dependency and full data privacy.
Every platform
One platform, one query language, one data model – for iOS, Android, .NET, Java, C/C++ (IoT), and browser-based JavaScript.
Always on
Data lives on-device. Reads and writes happen locally – when the network drops, your app keeps working. Sync reconciles automatically when connectivity returns, with version-vector conflict resolution that’s deterministic across devices.
Developer-friendly
Idiomatic SDKs that respect each platform’s conventions. SQL support and simple-to-use APIs for database CRUD. Flexible JSON schema means no migrations on app upgrade.
Edge AI-ready
On-device vector search for hybrid (keyword + semantic) queries against local data. Call local or remote ML and LLM models with the Predictive Query API. Build RAG and AI features that work fully offline – with no third-party search or vector store to integrate.
Any platform
- Native iOS, Android, and Windows
- .NET and Java for desktop and server-side apps
- C and C++ for IoT and embedded devices in any language
- JavaScript for always-on web apps that sync with mobile and the cloud
- Cross-platform: React Native, Ionic*, and Flutter* (*community-supported)
