About Website Technology Detector

A website technology detector helps when you size up a competitor, quote for a redesign, take over a client's old site with no handover notes, or want to know which platform built a page you like. Enter a URL and about 180 rules are matched against the HTML, script and style addresses, response headers, cookies and the meta generator tag.

It recognizes CMSs such as WordPress, Drupal, Joomla, DedeCMS, PbootCMS, Discuz! and Typecho, shops like Shopify, WooCommerce and Magento, frameworks from React and Next.js to Vue, Angular, Svelte and Astro, UI kits, servers such as Nginx, Apache, IIS and LiteSpeed, languages, CDNs, hosting, analytics like Google Analytics and Clarity, ads, fonts, payments, live chat, maps, video and security tools. Results are grouped by category, with versions when the site reveals them. It's passive: one page fetch, nothing more. For CDNs alone, the CDN Checker goes deeper.

FAQ

Website Technology Detector: questions and answers

How does the website technology detector work?
It fetches the page once and looks for known fingerprints, such as file paths like /wp-content/, script and style addresses, response headers, cookie names and the meta generator tag. About 180 rules cover the common technologies.
Why wasn't a technology detected?
Some tools leave no trace in the HTML or headers, load only through JavaScript after the page opens, or sit behind a CDN. We read the page as sent and don't run scripts, so these can be missed. You can search that HTML yourself in View Page Source.
Can I see version numbers?
When the site reveals them, for example in a meta generator tag, a versioned file path or an X-Powered-By header. Many sites hide versions, which is good security practice. The Security Headers Checker flags headers that give your own versions away.
Will the site know I checked it?
It sees one normal page request from our server with a desktop browser user agent, like any other visitor. Nothing is scanned or probed.
Is the technology detector free?
Yes, with no sign-up and no daily tasks used. Results aren't stored, and an hourly allowance per visitor stops abuse.
