LIGHTWEIGHT DATABASE SERVER FOR THE EDGE
Servidor Couchbase Edge
Run mission-critical apps on small edge hardware in stores, aircraft, and plants. Data stays local, apps keep working when the network drops, and sync resumes on reconnect.
Built for the edge, where networks fail
A lightweight database server for sites where a full cluster won’t fit. Your apps stay fast and available, with or without a connection.
Lightweight
Runs on resource-constrained hardware with as little as 1GB of RAM.
Reliable
Apps keep working when the network drops and sync automatically on reconnect.
Flexible data access
REST API for web and HTTP clients, plus native sync for Couchbase Lite apps.
One continuous data layer
Sync from cloud to edge to device on one platform with one data model.
What is Couchbase Edge Server?
Couchbase Edge Server is a lightweight database server that brings local data, queries, and sync to edge sites too small for a server cluster.
Kiosks, vehicle computers, industrial gateways, and single board computers. No Kubernetes required.
Apps read and write local data during outages. Changes sync automatically when the network returns.
A REST API for CRUD, SQL++ queries, and change feeds, plus WebSocket sync for Couchbase Lite apps.
Syncs up to Sync Gateway or App Services, down to Couchbase Lite, and across other Edge Servers.

How Edge Server works
One node for local data, queries, and sync
Edge Server handles the data work at each site, so your apps stay responsive and consistent across cloud, edge, and devices.
- Store
- Consulta
- Sync
- Monitor
- Asegure
Keep JSON documents on the edge node, so apps read and write fast with no round trip to the cloud.
Edge Server key capabilities
Built for constrained hardware
Runs where compute and memory can’t support a server cluster, with as little as 1GB of RAM on resource-constrained hardware.
Run SQL++ queries through the REST API. Browser apps and lightweight services get data with no Couchbase SDK.
Edge Server key capabilities
REST API for any client
Browser apps and HTTP clients read, write, query, and listen to changes. No Couchbase SDK or custom middleware required.
Replicate up to Sync Gateway or App Services and down to Couchbase Lite, with delta sync and automatic conflict resolution.
Edge Server key capabilities
Secure sync, cloud to device
Bidirectional sync up to Sync Gateway or App Services and down to Couchbase Lite, with TLS and version vector conflict resolution.
Edge to edge sync
Chain Edge Servers across sites, or combine layered and chained topologies to match how your business runs.
Listen to the changes feed so apps and services react the moment data changes at the site.
Edge Server key capabilities
REST API for any client
Browser apps and HTTP clients read, write, query, and listen to changes. No Couchbase SDK or custom middleware required.
Protect edge server data using TLS transport encryption, X.509 certificate-based authentication, and role-based access controls.

ARQUITECTURA
Store systems that keep selling
Edge Server runs on a small back office server. POS terminals, kiosks, and associates’ devices running Couchbase Lite sync to it over the store network. Checkout, pricing, and inventory keep working when the WAN drops, then sync to the cloud when it returns.
ARQUITECTURA
Onboard apps with no ground link
Edge Server runs on the aircraft’s onboard compute. Crew and passenger devices order meals and browse content against local data during the flight. When the plane lands, Edge Server syncs orders and inventory with the cloud.
REFERENCE APP
Get the Edge Server reference app
See how Edge Server powers an airline meal ordering system. The sample app serves orders from Edge Server on local data during the flight and syncs with the cloud when connectivity returns. Clone the source code, run it on your own hardware, and adapt the pattern to your stores, vehicles, or plants.
Where Edge Server fits in Couchbase Mobile
EMBEDDED DATABASE
Couchbase Lite
The embedded database inside your mobile and edge apps. Devices sync with Edge Server over the local network, so each one keeps working on its own.
SYNC AND ACCESS CONTROL
Pasarela de sincronización
Secure, bidirectional sync between Couchbase in the cloud and your edge sites, with access control enforced on the server.
MANAGED CLOUD SYNC
Servicios de aplicaciones
Fully managed sync in the cloud. Connect Edge Server upstream without running your own sync infrastructure.
Couchbase Edge Server FAQ
Get quick answers about running Couchbase Edge Server on constrained hardware, how it differs from Couchbase Lite, and how always-on sync works.
Couchbase Edge Server is a lightweight NoSQL database server built for resource-constrained edge hardware. It runs on as little as 1GB RAM and exposes a REST API for local app access.
Couchbase Lite is an embedded database inside a single app. Edge Server is a database server that multiple apps and clients on the same local network can access via REST API.
Yes. Edge Server stores data locally and keeps apps running during outages. It syncs automatically with Couchbase in the cloud when connectivity is restored.
Edge Server runs on resource-constrained hardware with as little as 1GB RAM, making it suitable for retail kiosks, restaurant terminals, warehouse systems, and connected vehicles.
Apps connect to Edge Server via a REST API, allowing any client application or programming language to read and write data without requiring a Couchbase-specific SDK.
