About A/B Test Inspector

A/B Test Inspector shows every experiment running on the page you are viewing — and stays open while you browse. It automatically detects the A/B testing or personalization platform in use, so you don't have to configure anything. WHAT IT DOES - All running tests at a glance: name, ID, status and your variation - Personalization filter: instantly see which experiments are personalization rollouts - Page mapping: see which pages (PDP, PLP, navigation, checkout …) each test is attached to - Filter chips by page type: Homepage, PDP, PLP, Navigation, Search, Cart, Checkout, Sitewide - Raw JSON view of every experiment for debugging - Auto-refreshes when you switch tabs or navigate WHO IT IS FOR CRO teams, UX/UI designers, developers and QA who need to verify which experiments and personalizations are live on a website. PRIVACY The extension only reads the testing platform's public client object exposed on the page you are viewing. It does not collect, store or transmit any data. Everything stays in your browser.
