What is Endless Testing?

Endless Testing is an autonomous A/B testing platform. Point it at a URL, and it will:

1. Generate tests — AI analyzes your page and creates copy variants targeting high-impact elements
2. Allocate traffic — Thompson sampling (Bayesian bandits) routes visitors to the best-performing variants
3. Detect winners — Statistical evaluation auto-promotes winners when confidence thresholds are met
4. Iterate — The winner becomes the new control, and AI generates new challengers. Repeat forever.

How it works

You: endlesstesting run https://mysite.com
  → AI crawls page, identifies testable elements
  → Generates 5 tests × 3 variants each
  → SDK on your site serves variants to visitors
  → Thompson sampling finds winners
  → Winners become new baselines
  → New variants generated automatically
  → Your site gets better continuously

Three ways to use it

CLI

npm install -g endlesstesting
endlesstesting auth <your-api-key>
