Smarter than A/B testing

Traditional A/B tests waste traffic on losing variants. Bandit algorithms learn in real-time and automatically shift traffic to winners.

Multi-Armed Bandit Algorithms

Choose from Epsilon-Greedy, UCB1, or Thompson Sampling. Each one automatically balances exploration of new variants with exploitation of proven winners.

Real-Time Optimization

Sub-100ms assignment latency. In-memory algorithm state with Redis caching means your users never wait — and traffic shifts to winners within minutes, not weeks.

Assignments served in <100ms

AI-Generated Variants

Let AI analyze your best-performing content and generate new variants. Eight generation strategies from emotional appeal to urgency to social proof — all data-driven.

Drop-In SDK

Five lines of code to integrate. Works in any JavaScript environment — browser, Node.js, edge functions. Automatic event batching and retry logic built in.

npm install @bandit/sdk

Three steps to smarter experiments

From integration to optimization in minutes, not months.

1

Integrate the SDK

Install the package, initialize with your API key, and call getAssignment() wherever you need a variant.

2

Create Experiments

Define your variants and pick an algorithm in the dashboard. Add headlines, images, CTAs — or let AI generate variants for you.

3

Watch It Optimize

Bandit automatically shifts traffic to top performers. Track conversions, revenue, and confidence in real-time. The algorithm gets smarter with every interaction.

Five lines of code.
Infinite optimization.

The SDK handles assignment caching, event batching, and automatic retries. You just show the variant and track conversions.

app.ts
import { BanditClient } from '@bandit/sdk';

const bandit = new BanditClient({
  apiUrl: 'https://api.runbandit.com',
  apiKey: 'your-api-key'
});

// Get the best variant for this user
const { treatment } = await bandit.getAssignment(
  'headline-experiment',
  'user-123'
);

// Track when they convert
bandit.trackEvent({ 
  eventType: 'CONVERSION',
  value: 29.99
});
