Generic backend with API, storage, and realtime capabilities
Self-hostable backend offering standard building blocks—multi-protocol API, persisted data, realtime notifications, user management, and extensibility—so you can focus on business logic.

Kuzzle is a production-ready backend platform that provides the foundational features common to modern applications, eliminating repetitive development work. Built for web applications and IoT networks, it delivers a standardized multi-protocol API, persistent data storage with advanced search, realtime pub/sub notifications, and integrated user management out of the box.
Developers building web apps, mobile applications, or complex IoT systems will benefit from Kuzzle's extensible framework. It supports tens of thousands of concurrent users and can be deployed anywhere. The platform includes an integrated development framework for custom business logic, client SDKs for accelerated frontend work, and leverages Elasticsearch and Redis for storage and caching.
Scaffold a new application using Kourou, register custom API controllers in TypeScript or JavaScript, and deploy using Docker. Kuzzle handles authentication, permissions, data querying, and realtime subscriptions, letting teams ship high-value features faster without rebuilding standard backend infrastructure.
When teams consider Kuzzle, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
IoT Device Network
Connect thousands of MQTT devices with realtime data ingestion, persistent storage, and live dashboard updates without custom infrastructure.
Collaborative SaaS Platform
Build multi-tenant applications with user authentication, role-based permissions, and realtime collaboration features in weeks instead of months.
Mobile App Backend
Leverage client SDKs and standardized APIs to rapidly develop iOS/Android apps with offline sync, push notifications, and advanced search.
Real-Time Analytics Dashboard
Stream sensor or event data into Elasticsearch, subscribe to filtered updates, and visualize changes instantly without polling or custom WebSocket code.
Kuzzle provides a multi-protocol API supporting HTTP, WebSocket, and MQTT, allowing diverse clients from web browsers to IoT devices to connect using the same backend.
Yes, Kuzzle is production-proof and can serve tens of thousands of concurrent users with strong performance when properly deployed with Elasticsearch and Redis.
Register custom controllers and actions using the integrated framework in TypeScript or JavaScript. Kuzzle provides request/response handling, validation, and access to storage and realtime engines.
Kuzzle requires Elasticsearch for data storage and search, and Redis for caching and pub/sub. These can be run via Docker Compose or managed services.
Yes, Kuzzle offers SDKs for multiple platforms to accelerate frontend and IoT development, abstracting API calls and realtime subscriptions into idiomatic client libraries.
