About Kirro

Kirro is an A/B testing tool built for marketers and founders who run a website alongside many other responsibilities and do not have a dedicated conversion team. It adds to a site with a single paste through Google Tag Manager, then reads live pages and suggests changes that are likely to lift conversions, explaining what to change and why.

Tests are built in a visual editor where you click any element and rewrite it, with no code needed. Existing GA4 goals are used automatically as test objectives, so results can be read in plain English rather than through dashboards. The company says its statistics work with modest traffic and that its script is small enough not to slow pages down.

Kirro says it reports when a test has no clear winner instead of inflating results. It offers a 14-day free trial with unlimited tests and visitors, and a paid plan priced per month with an annual discount. It is not aimed at teams that need feature flags, server-side testing or complex experiments.
