Website Technology Detector: Tech Stack Scanner

Points at any URL and identifies what's actually running underneath — CMS, ecommerce platform, JS framework, analytics and marketing tags.

Matches against thousands of known technology signatures, so the read is specific, not a guess from page-source vibes.

Useful for a quick one-off check or wired into a research pipeline for hundreds of sites at once.

Each result carries the evidence behind it, not just a label: the final URL after redirects, the HTTP status, the page title, the response headers used as signals, and the generator meta tag — which is often the single strongest CMS signal and frequently carries an exact version.

Every technology found comes with one or more category labels, a version where the site exposes one, and a confidence score. Confidence measures how cleanly the fingerprint matched; it is signal strength rather than independent verification.

Server-side components are often visible too. Response headers and platform conventions routinely reveal the web server, programming language and database — a typical CMS site returns those alongside the CMS itself. What cannot be seen is anything leaving no observable trace.

A site that blocks automated traffic returns an error row rather than a confident “nothing detected”. Reporting a block as an empty result is the main way naive detectors mislead people, and the two are kept distinct here.

Detection reads the single URL you supply, so a technology used only inside a checkout or account area will not be seen from a homepage. Absence of a technology means no signature matched — not proof the site does not use it.

Versions are reported only where a site publishes them, most often through a generator meta tag, so most entries return no version at all. Fingerprints are refreshed periodically rather than continuously, because platform signals change as new versions ship.

Pages are fetched once, streamed and capped, then discarded. There is no crawling beyond the URL you asked for and nothing behind a login is touched.
