Experiment Detector

About

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.

Privacy Friendly
Experiment Detector only runs when you click the icon, only works on the current tab, and never sends any data to external servers.
