Why use a web-based tool instead of an extension?

Web-based tools require no installation, work on mobile devices, and do not consume background browser memory.

How does detection work?

It fetches the page's real HTML and checks it against known technology signatures — script sources, DOM markers, generator meta tags, and response headers. Only technologies with an actual matching signal are listed; nothing is guessed.

Why couldn't it detect a URL I entered?

Some sites block automated fetch requests. Switch to "Paste HTML Source" and paste the page's HTML directly instead.
