Experiment Detector

Detects A/B testing and experimentation platforms running on websites

See If A/B Tests Are Running on Websites Experiment Detector is a handy productive Chrome extension that shows you to spot any A/B tests and experimentation platforms are active on websites you visit. It's a useful tool for marketers, developers, or anyone curious about how websites are optimizing their user experience. It is in beta phase. Key Features Platform Detection: Quickly identifies common experimentation platforms like Optimizely, VWO, Google Optimize, LaunchDarkly, Split.io, Eppo, Statsig, Amplitude Experiment, and GrowthBook. Experiment Information: Shows which specific experiments are running on the page, including their names, IDs, and what variation you're seeing. Tag Management Insights: Spots tag management systems like Google Tag Manager or Adobe Launch that often deploy experiments. Analytics Overview: Identifies which analytics tools are present, giving context to how experiment data is being collected. Dynamic Detection: Finds experiments as they load, even those implemented after the initial page load. Simple Interface: Presents findings in a clean, easy-to-understand dashboard. Great For Marketers: See how other companies are testing their websites Developers: Check if unexpected behavior is from an active experiment UX Designers: Observe how others implement design tests Digital Analysts: Understand experimentation setups Product Managers: Keep tabs on product testing approaches How It Works The extension uses pattern matching and JavaScript environment analysis to detect experimentation platforms. It looks for specific signatures in the page source, checks for known JavaScript objects, and examines localStorage and cookies that might contain experiment data. The detection works by identifying: Common experimentation platform signatures in code Active experiments and their variations Tag management systems that deploy experiments (the detection logic will be updated regularly once new information is available). User identification methods for experiments: Just click the extension icon in your Chrome toolbar while browsing, and it will scan the current page and show you what it finds. A Note on Accuracy: This tool uses heuristic detection methods which may occasionally produce false positives or miss some experiments. The results should be considered informational and may need verification for critical applications.
