New In 1.1

    Release 1.1 June 2026

    New Features

    Fine-Grained Access Control

    Couchbase Edge Server now supports fine-grained access control for downstream edge clients. You can define read and write permissions per user at the database, scope, and collection level, enabling multiple applications to share a single Couchbase Edge Server instance without exposing data across application boundaries.

    Access control is opt-in and is enabled at the server level using the enable_user_access_control configuration property. Named query access can also be restricted based on a user’s collection-level permissions.

    For more information, see:

    Token Rotation Without Restart

    Couchbase Edge Server now supports JWT-based replication credential rotation without requiring a server restart. Instead of embedding the JWT token inline in the replication configuration, you specify a file path to the token. Couchbase Edge Server loads the token when a replication starts, and can optionally monitor the file for changes and reconnect with the updated token automatically.

    For more information, see Rotate Replication Credentials Without Restart.

    CORS Support

    Couchbase Edge Server now supports configurable Cross-Origin Resource Sharing (CORS) policies. This enables browser-based clients and JavaScript SDKs, including the Couchbase Lite JavaScript SDK, to replicate directly with Couchbase Edge Server. CORS is disabled by default and must be explicitly enabled in the database configuration.

    For more information, see Configure CORS.

    Windows Support

    Couchbase Edge Server is now supported on Windows Server 2022, Windows Server 2025, Windows 10, and Windows 11 (x86_64). Windows 10 and Windows 11 are supported for development and testing only.

    For more information, see Supported Platforms.

    Linux ARM64 Support

    Couchbase Edge Server is now supported on Linux ARM64 (aarch64), including Ubuntu 22.04+. This enables deployment on ARM-based edge devices, single-board computers, and industrial gateways.

    For more information, see Supported Platforms.

    Release 1.0 (March 2025)

    New Features

    Couchbase Edge Server

    Couchbase Edge Server is a lightweight REST and sync server for Couchbase Mobile databases based on Couchbase Lite Core (LiteCore).

    With Couchbase Edge Server, you can perform scalable, offline-first data sync at the edge in resource constrained environments.

    Couchbase Edge Server possesses the following features:

    • Compact and lightweight: ~10 MB codebase, typically uses < 50 MB RAM.

    • Flexible data handling: Serves existing Couchbase Lite database files, or can create its own CRUD-based document access.

    • Real-time updates: Push notifications for data changes on the changes feed to save bandwidth caused by polling and reduce latency.

    • Advanced querying: Supports SQL++ queries.

    • Local synchronization: Acts as a database sync server for local Couchbase Lite clients.

    • Upstream integration: Functions as a database sync client for upstream Sync Gateway, Capella App Services, or other instances of Edge Server.
