Always-on apps. Always-fast experiences. With or without the network.

When apps go down, revenue follows. Couchbase Mobile is how the world’s leading enterprises – from PepsiCo to Princess Cruise Lines to PG&E – run apps that simply cannot fail. An embedded database, built-in sync, SQL++ queries, and on-device vector search in one unified platform from cloud to edge to device.

Build always-on mobile, edge, and web apps with one data platform that syncs between the cloud, on-prem, device, and everywhere in between – online or off.

Zero downtime

Apps stay fully functional when networks fail. Data syncs automatically when connectivity returns.

Real-time data sync

Built-in sync from cloud to edge to device. Delta sync minimizes bandwidth. Peer-to-peer sync without internet.

Works everywhere

Native mobile, cross-platform, embedded devices, web apps, and Edge Server for constrained hardware. Secure from cloud to edge.

Edge AI ready

Vector search in the cloud, on prem, and on device for AI w/o internet. Future-proof apps for edge AI. Use local data for context and privacy.

Couchbase Mobile key capabilities

Couchbase Mobile is the operational database platform for mission-critical apps that must never go down. Embed a full database into your app, sync seamlessly from cloud to edge to device, and run AI-powered features on-device – all from one unified platform that keeps working when the network doesn’t.

  • Embedded database

    Couchbase Lite stores data on-device with SQL++, full-text search, and vector search on every major platform.

  • Secure data sync from cloud to edge

    Cloud-to-device sync with automatic conflict resolution via Capella App Services or Sync Gateway. Peer-to-peer sync between devices, no internet required.

  • Cloud-to-edge AI support

    Vector search runs in the cloud/on-prem with Couchbase, and on-device with Couchbase Lite for AI without internet.

  • Resource-constrained environments

    Edge Server runs where computing resources are minimal. Sync data with local mobile apps, web apps, other Edge Servers, and the cloud.

Accelerated development

  • Native support for iOS, Android, and Windows platforms; .NET and Java support for desktop and web server apps
  • C and C++ means you develop for edge devices in any language
  • JavaScript support for always-on web apps that sync with mobile apps and the cloud
  • Cross-platform support with React Native, Flutter*, Ionic* (*community supported)
  • Vector search on-device works even without the internet

Comprehensive end-to-end solution

Cloud database
Use Couchbase Capella, our hosted Database-as-a-Service, or install and manage Couchbase Server on your own public or private cloud.

Edge-ready database
Deploy Couchbase Server at the edge to support thousands or more edge clients. For resource-constrained edge environments with a few hundred local clients, you can deploy Edge Server.

Embedded mobile database
Couchbase Lite is the embeddable version of Couchbase for mobile apps that stores data locally on the device.

Secure mobile data sync
Choose hosted data sync with Capella App Services, or install and manage Couchbase Sync Gateway yourself.

Peer-to-peer data sync

  • Sync data between peer devices without the internet
  • Discover peers automatically over IP networks for iOS/Android
  • Configure small mesh topologies automatically
  • Connect over Bluetooth
  • Switch networks automatically to ensure uninterrupted sync

Database server for resource-constrained environments

  • Couchbase Edge Server runs anywhere on resource-constrained hardware, such as small, single-board computers
  • Edge Server addresses the challenge of limited compute capacity inherent in many edge deployments, which are often constrained by space, power, and logistics

Couchbase Mobile FAQ

Get quick answers to questions about how Couchbase Mobile supports seamless data sync, security, and edge vector search.

Couchbase Mobile is an embedded NoSQL database for network resilient iOS, Android, IoT, and web apps with built-in cloud-to-edge sync and on-device vector search.

Couchbase Mobile is built for apps that must be fast and reliable. It stores data locally on the device so users stay productive without an internet connection, then syncs when connectivity returns.

Couchbase Mobile supports iOS, Android, Windows, .NET, Java, and web via JavaScript, plus embedded edge devices through a C++ and C-API. It also supports cross-platform frameworks like React Native.

Data syncs between devices and the cloud via Capella App Services or self-managed Sync Gateway, with automatic conflict resolution and peer-to-peer sync support.

Yes. Couchbase Lite supports on-device vector search for edge AI and RAG applications, enabling semantic search even without an internet connection when using local models.
