# Cuttl

> Cuttl is a website optimisation tool that combines heatmaps, session recordings and A/B testing in one product. It shows where visitors get stuck, turns that evidence into an A/B test, and shows whether the change improved the conversion rate. Everything runs from one JavaScript snippet.

## What Cuttl does

- Heatmaps and session recordings: click maps, rage click detection, funnels and automatic issue detection.
- Test ideas: each issue becomes a test idea with its recordings, heatmap and a count of the sessions it affects.
- A/B testing: A/B, split URL and multivariate tests. Bayesian statistics by default, with sequential and fixed-horizon options and guardrails that pause a variant that hurts other metrics.
- Per-variant heatmaps and recordings, so you can see why a variant won.
- Impact reports: compares the conversion rate before and after a test or release, and says whether the change helped, made no clear difference or made things worse.
- Before-and-after checks for sites without enough traffic to run a test.
- Integrations: a built-in MCP server for Claude, ChatGPT and Gemini, a REST API, webhooks and Slack, data exports, CDN geo headers (Cloudflare, Vercel, CloudFront) and OpenID Connect single sign-on.
