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. The cycle repeats.

How it works

You: et round start example.com --url https://example.com
  → AI crawls the page and identifies testable elements
  → A round of variants is created
  → The snippet on your site serves variants to visitors
  → Thompson sampling finds winners
  → Winners become new baselines
  → New variants are generated
  → The site keeps improving

Three ways to use it

CLI

Install et, then:

et login --email [email protected]
et site add https://example.com
et round start example.com
et results example.com
