Install an SDK

Pick the SDK for your runtime. Each one sends events to the same ingest endpoint and evaluates feature flags locally from the same rules, so a user lands in the same rollout whichever you choose.

The key in these snippets comes from the console: Get an API key

At a glance

Packages
@prodantix/sdk (web), prodantix_sdk (Dart), prodantix_sdk_flutter (Flutter), prodantix-sdk (Python)
Credential
The public project key: Projects & keys
Endpoints
Hosts and contracts: REST

Browser and Node

Bash
bun add @prodantix/sdk

# React apps also take the adapter:
bun add @prodantix/react
JavaScript
import { createWebClient } from '@prodantix/sdk/web';

const prodantix = createWebClient({
  apiKey: PRODANTIX_PUBLIC_KEY,
  host: 'https://eu.api.prodantix.com',
  flagsHost: 'https://api.prodantix.com',
});

prodantix.capture('order.completed', { properties: { amount: 4200 } });
JavaScript
import { ProdantixProvider, useProdantix } from '@prodantix/react';

<ProdantixProvider options={{ apiKey: PRODANTIX_PUBLIC_KEY, host: 'https://eu.api.prodantix.com' }}>
  <App />
</ProdantixProvider>

const prodantix = useProdantix();
prodantix?.capture('order.completed');

Flutter and Dart

Bash
flutter pub add prodantix_sdk_flutter

# Dart server or CLI, without the Flutter layer:
dart pub add prodantix_sdk

Python server

Bash
pip install prodantix-sdk

Your project key is public: it names the project, it grants no access to its data, so it belongs in client code. A server key, which can write, never does.

Where to go next

Quickstart: capture a first event and read it back. Each package’s full surface is under Packages, and framework wiring (React, Vue, Svelte, Angular) under Frameworks.
