Why Kuzzle ?

Kuzzle is a generic backend offering the basic building blocks common to every application.

Rather than developing the same standard features over and over again each time you create a new application, Kuzzle proposes them off the shelf, allowing you to focus on building high-level, high-value business functionalities.

Kuzzle enables you to build modern web applications and complex IoT networks in no time.

  • API First: use a standardised multi-protocol API.
  • Persisted Data: store your data and perform advanced searches on it.
  • Realtime Notifications: use the pub/sub system or subscribe to database notifications.
  • User Management: login, logout and security rules are no more a burden.
  • Extensible: develop advanced business feature directly with the integrated framework.
  • Client SDKs: use our SDKs to accelerate the frontend development.

The easiest way to start a Kuzzle application is to use Kourou:

 🚀 Kourou - Scaffolds a new Kuzzle application

  ✔ Checking destination
  ✔ Prepare temporary folder
  ✔ Cloning template repository
  ✔ Copying template files
  ✔ Cleaning up

 [✔] Scaffolding complete!
 [✔] Use cd playground && docker compose up -d to start your Kuzzle stack.

Then you need to run Kuzzle services, Elasticsearch and Redis: kourou app:start-services

Finally you can run your application inside Docker with npm run docker:dev

Kuzzle is now listening for requests on the port 7512!

Use the framework

Your first Kuzzle application is inside the app.ts file.

For example, you can add a new API Controller:

import { Backend } from 'kuzzle';

const app = new Backend('playground');

app.controller.register('greeting', {
  actions: {
    sayHello: {
      handler: async request => `Hello, ${}`

  .then(() => {'Application started');

Now try to call your new API action by:
