Frequently asked questions
How does detection work?
By matching the page's HTML, scripts, cookies and response headers against signatures of about 60 popular technologies.
Why is something missing?
Tools loaded only after JavaScript runs, server-side code and custom-built stacks can't always be seen from the outside.
Is this accurate?
Signatures are specific (e.g. /wp-content/ for WordPress, cf-ray for Cloudflare), so false positives are rare.
