🚀 A/B Test Identifier – Instantly Uncover A/B Tests on Any Website -Welyft A/B Test identifier is the ultimate Chrome extension for professionals in Conversion Rate Optimization (CRO), User Experience (UX), and web performance analysis. -With a single click, detect hidden A/B tests, multivariate experiments, and dynamic personalization on any site you visit. 🔍 Key Features -Automatic detection of leading testing & personalization platforms: Optimizely, AB Tasty, VWO, Kameleoon, Dynamic Yield, ( and more to come) -Reveals active experiments and variations – often includes test or campaign IDs. -Compatible with e-commerce stores, SaaS platforms, landing pages, and marketing sites. -Lightweight & privacy-first: no tracking, no data collection. 👥 Who It’s For -CRO and Growth Marketers – uncover competitor testing strategies -UX/UI Designers & Web Analysts – enhance audit speed and depth -Front-End Developers & QA Testers – identify unexpected changes -Digital Consultants & Curious Explorers – spot optimization tactics on the fly 📈 What You Can Do -Reveal A/B tests and personalization tactics on live websites -Identify testing tools used by competitors or clients -Accelerate UX audits, QA processes, and site evaluations -Stay inspired by real-world experimentation examples ❓ FAQ – Frequently Asked Questions How does A/B Test identifier identify experiments? -We use public front-end APIs exposed by A/B testing and personalization tools to collect experiment metadata. These APIs are typically available in the browser for testing/debugging purposes. Can the extension collect data from my experiments? No. A/B Test identifier only detects publicly exposed information, such as: -The experiment name -The type of experiment (e.g., A/B test, personalization) -It does not collect or expose private data, such as audience segments, performance metrics, targeting rules, or results. The extension operates read-only and does not send any data outside your browser. What types of tests can it detect? -A/B tests -Split URL tests -Multivariate tests -Dynamic content personalization Depending on the tool and setup, it may also detect which variation is being served. Which testing tools are supported? -We support a wide range of platforms including: -Optimizely, AB Tasty, VWO, Kameleoon, Dynamic Yield, (and more to come) The detection engine is regularly updated to stay current with the ecosystem. Why am I not seeing any tests? Several possible reasons: -Cookie consent not granted – some tests require marketing cookies to activate. -Unsupported platform – we may not yet support the tool in use. -Server-side test – server-side experiments often don't expose client-side data. -No active experiments – the site may not be running any tests at the moment. Does the extension send any data to Welyft? -Absolutely not. All detections happen locally in your browser. No data about your browsing or detected experiments is sent to Welyft or any third party. Changelog: 1.2 : Fix on Kameleoon & ABTasty API
