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.
Reads and writes hit the embedded database at memory speed – no network round-trip, no stalled UI.
Apps keep reading and writing when the network fails. Sync catches up automatically when connectivity returns.
On-device vector search powers semantic queries and RAG with no internet dependency and full data privacy.
One platform, one query language, one data model – for iOS, Android, .NET, Java, C/C++ (IoT), and browser-based JavaScript.
Ship always-on mobile apps without building data sync yourself. Couchbase Lite embeds a complete NoSQL database – with SQL++ queries, full-text and vector search, reactive listeners, and built-in sync – so you focus on app features instead of distributed systems infrastructure.
SQL++ extends SQL to JSON. Write JOINs, aggregations, and complex filters locally, reusable from device to cloud.
Build private, on-device RAG and similarity features with local hybrid vector search and zero server lag.
Couchbase Lite syncs via Wi-Fi/Bluetooth with auto-discovery, mesh support, and cross-platform iOS/Android support.
Couchbase Lite enables offline web apps to sync with mobile and cloud, all from a single JS SDK.
Secure Couchbase Lite data with AES-256, TLS, BYOK, field-level encryption, and auto-purge on access revocation.
Run local AI models with the Predictive Query API for real-time inference at the point of interaction.
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.
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.
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.
