Security and authentication

Secure your applications, data, and APIs via an RBAC rights system. Identify your users with +500 authentication strategies (OAuth2, OpenID…)

Data storage

Structure and store your JSON documents securely via the standard Kuzzle API, with CRUD queries, search and real-time Pub/Sub.

Real-time Engine

Use Koncorde’s real-time Pub/Sub engine to distribute data instantly and provide a real-time user experience for your web, mobile, and IoT applications.

Multi-protocol API

Choose the API communication protocol adapted to your use cases, whether it’s HTTP, Websocket, or MQTT.

Cluster Mode

Configure Kuzzle Backend Open Source in a masterless cluster of two or more nodes for high availability and effortless deployment at scale.

Develop your applications with our SDK

Kuzzle Backend


Develop modern web applications with React, Vue, or Angular and take advantage of Kuzzle Backend’s real-time features to create a smooth user experience and synchronize data between users.

Kuzzle Backend


Create native iOS and Android mobile applications by embedding the Kotlin, Dart, or JavaScript SDKs in your applications to synchronise your data, manage offline use, and notify your users.

Kuzzle Backend


Integrate the data from your IoT sensors using the Kuzzle Backend API and the push or pull data collection protocol: HTTP, MQTT, or WebSocket, either as a plugin or a microservice.

“As we have a very small development team, Kuzzle has been instrumental in allowing us to focus on our customers’ business needs. Kuzzle’s authorization system, search capabilities, and scalability made it easy for us to deploy the backend for our mobile applications and websites.
To be up-and-running quickly, I recommend Kuzzle’s certified trainers. They gave us what we needed to build our first draft concept in just a week.”
