Kirro is a lightweight A/B testing platform that helps marketers and founders optimize website conversions with AI-suggested tests, one-click Google Tag Manager integration, and plain-English results.
What is Kirro?
Kirro is an A/B testing tool for websites that suggests what to test, runs experiments, and reports results in simple language. It takes a website URL as input, automatically detects elements for testing, and outputs clear winning variations or an honest "not enough data" verdict. The platform runs on any site via a 9KB script installed through Google Tag Manager and is built by the Kirro team.
Key Features
- AI test suggestions — Kirro reads your live pages and generates ranked test ideas (e.g., headline rewrites, CTA changes) with an estimated impact percentage.
- One-click GTM install — Add Kirro to your site with a single click through Google Tag Manager; no manual coding required.
- Visual editor — Click any page element and rewrite its text or styling directly, without touching HTML or CSS.
- GA4 goals integration — Your existing Google Analytics 4 conversion goals automatically become test objectives.
- Plain-English winners — Test results are summarized in simple language, e.g., "Headline rewrite +13.4%".
- Honest outcomes — If data is insufficient, Kirro says so rather than fabricating a winner.
- Small-traffic friendly — Works with as few as 5,000 monthly visitors using smarter statistical models.
- Lightweight script — Only 9KB, roughly 16× smaller than typical competitors (100-200KB), keeping your site fast.
