Kuzzle

Kuzzle is a ready-to-run backend for IoT networks, web, and mobile apps. Instead of rebuilding the same plumbing for every project, you get authentication, data storage, search, and real-time messaging out of the box and extend them with your own business logic.

Devices and clients talk to a single multi-protocol API over MQTT, WebSocket, and HTTP. Data persists in Elasticsearch with advanced search and filtering, and the real-time engine pushes updates through pub/sub or live database subscriptions. Built-in user management handles login, roles, and security rules.

Kuzzle is extensible through an integrated framework and ships with client SDKs across several languages to speed up frontend and device development. It self-hosts anywhere, including on-premises, and is licensed under Apache-2.0.
