## What it is
Kuzzle is an open-source, self-hostable general-purpose backend framework built on Node.js that exposes a multi-protocol API (HTTP, WebSocket, MQTT) over persistent data storage with advanced search via Elasticsearch and Redis. It ships with ready-made building blocks such as realtime pub/sub notifications, user management and security rules, and an integrated framework for custom business-logic plugins.

## Use cases
- self-host a realtime backend for web and mobile apps
- build an IoT platform that ingests sensor data over MQTT
- add pub/sub and database-change notifications to an application
- manage users, login and security rules without writing them from scratch
- run advanced full-text and geospatial searches over persisted data
- scaffold a scalable API server with Docker Compose
- extend a generic backend with custom business-logic plugins

## When to choose
- you want a ready-made, self-hosted backend with realtime, storage, search and auth out of the box
- you are building IoT networks or smart-city/hypervision platforms that need MQTT and large-scale device management
- you prefer an API-first, multi-protocol server backed by Elasticsearch and Redis
- you want to focus on high-value business features instead of boilerplate backend plumbing

## When to avoid
- you need a lightweight microservice rather than a full backend platform with its own stack
- your data model fits better in a relational database with strict SQL requirements
- you want a managed BaaS and prefer not to operate Elasticsearch and Redis yourself
- your team is not comfortable with Node.js and JavaScript
