This reads the site's published HTML only. It sees what the server sends, not what runs afterwards in a browser.

FAQ

Frequently asked questions

How does the tech stack checker work?

+

It fetches the page's published HTML and inspects four signals: script URLs, inline script contents, meta and DOM markers, and the HTTP response headers and cookies. Each signal is matched against a table of known technology fingerprints.

Can it detect everything a site uses?

+

No, and it says so. The checker reads published HTML only, so tools loaded at runtime by a tag manager may not appear. When a tag manager is detected, the results flag that the list may be incomplete rather than implying it is exhaustive.

What do 'confirmed' and 'likely' mean?

+

Confirmed means an unambiguous signal was found, such as a Google Tag Manager container ID or a server header. Likely means only a heuristic marker matched, such as a DOM attribute that a framework usually leaves behind but which can occur by coincidence.

Is the tech stack checker free?

+

Yes. No account is required, and full results are shown without a signup wall.
