Stop Losing Conversions While You Test
Traditional A/B tests waste 50% of traffic on the losing variant for weeks. RunBandit's multi-armed bandit algorithms shift traffic to winners automatically — from day one.
Traffic automatically shifts to the best-performing variant. No manual intervention needed.
Built for teams that ship fast
A better way to experiment
- Wait weeks for statistical significance
- 50% of traffic wasted on the loser
- Manual analysis required to pick a winner
- Converge on winners in days, not weeks
- Minimize wasted traffic automatically
- Real-time dashboard — zero manual work
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.
Four Bandit Algorithms
Epsilon-Greedy, UCB1, Thompson Sampling, and Contextual Linear UCB. Each one automatically balances exploration with exploitation — no manual traffic management.
Real-Time Optimization
Sub-100ms assignment latency. In-memory algorithms with Redis caching shift traffic to winners within minutes, not weeks.
Developer-Native
TypeScript SDK, clean REST API, deployed at the edge. Five lines of code to integrate. Not a marketer's drag-and-drop tool.
AI-Generated Variants
Don't just test what you think of — let AI analyze performance patterns and suggest new treatments automatically.
Composite Experiments & Funnels
Chain experiments across your entire funnel — from landing page to checkout. Track user progression through multi-step conversion flows.
How RunBandit compares
Purpose-built for algorithmic optimization, not bolted on as an afterthought.
Three steps to smarter experiments
From integration to optimization in minutes, not months.
Integrate the SDK
Install the package, initialize with your API key, and call getAssignment() wherever you need a variant. Five minutes, five lines of code.
Create Experiments
Define your variants and pick an algorithm in the dashboard. Add headlines, images, CTAs — or let AI generate variants for you.
Watch It Optimize
RunBandit 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. Your tests are now self-optimizing.
The SDK handles assignment caching, event batching, and automatic retries. You just show the variant and track conversions.
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-test', 'user-123');
// Track when they convert
bandit.trackEvent({ eventType: 'CONVERSION', value: 29.99 });
Your A/B tests shouldn't need babysitting.
Join teams already using intelligent algorithms to get more conversions, more revenue, and fewer wasted impressions.
