From domain to experiment map in three steps
No browser extension, no tag access, no login to the site you're looking at.
- 1
Enter a domain
Any public site. Pick desktop or mobile and how many page types to crawl.
- 2
We load it in a real browser
Headless Chromium accepts the cookie banner, then visits the homepage and the site's main page types, like product pages or articles.
- 3
Get the full experiment map
Every test, variant, traffic split and audience we can recover, with the evidence behind each one. Export it as JSON.
Built to find what devtools miss
Testing tools hide their state in different places. The inspector checks all of them on every page it visits.
Vendor-level decoding
Reads Optimizely datafiles, VWO and AB Tasty globals, Adobe Target decisions, Kameleoon, Dynamic Yield and more, straight from the page.
Feature flags too
Picks up GrowthBook, PostHog, Statsig, LaunchDarkly, Amplitude and Split payloads from network responses.
In-house frameworks
Finds custom assignment maps on window globals and experiment configs in first-party bundles, then recovers names from call sites.
Variants and traffic splits
See every variation, its allocation, the audience it targets and which variant you were bucketed into.
Consent-aware crawling
Handles common cookie banners so tools that only fire after consent still show up in the results.
Evidence you can check
Each finding links back to the cookie, global, request or dataLayer event it came from. No black box.
Who it's for
Growth & CRO teams
See what competitors are testing on pricing pages, checkouts and onboarding before you spend a sprint on the same idea.
Agencies
Audit a prospect's experimentation stack in a minute and walk into the pitch knowing what they run and how mature it is.
Engineers & QA
Check which flags and variants your own production site serves, per device, without digging through devtools.
Common questions
How does it detect experiments?+
It loads the site in headless Chromium and inspects vendor globals, network responses, tracking beacons, cookies, local storage and every dataLayer push from page start. Each detector is written for a specific platform, plus generic heuristics for in-house setups.
Can it see server-side tests?+
Only if they leave a trace in the browser, such as a cookie, a flag payload or an exposure event. Purely server-side splits that render different HTML with no marker can't be seen from outside.
Why does one scan find more tests than another?+
Tests are often limited to certain pages, devices or audiences. Crawling more pages and switching between desktop and mobile usually surfaces more of them.
Do I need an account?+
No. Enter a domain and run a scan. Results can be downloaded as JSON.
