Tech Stack Detector

High means two or more distinct patterns matched, which is rarely wrong. Medium means a single pattern hit, and that's where false positives live, for example a blog post that merely mentions Cloudflare can trip a text match. Treat medium results as leads to verify, not conclusions.

Yes, CMS detection is the strongest category because platforms leave loud fingerprints. WordPress exposes wp-content paths and a generator meta tag, Shopify loads from cdn.shopify.com, Webflow ships data-wf attributes, and Wix, Squarespace, Ghost, and Drupal all have similar tells the signatures cover.

Next.js, React, Vue, Nuxt, Svelte, Angular, Astro, and Remix. Each has recognizable output, like the __NEXT_DATA__ script for Next.js, the __nuxt root div for Nuxt, or ng-version attributes for Angular. Note that a Next.js match usually implies React underneath even when React isn't separately flagged.

Some sites block automated fetches, and some custom-built stacks simply leave no recognizable markers in their HTML. Server-rendered pages that strip framework artifacts can also read as blank. An empty result means no known signature matched, not that the site runs nothing.

No. It downloads the page HTML once and runs pattern matching on the text, the same as reading view-source. Nothing executes on the target, no account is needed, and no third-party detection API is called.

It uses the same signature-matching idea with 25+ curated technologies rather than thousands, which covers the CMS, framework, analytics, and payments questions most research actually asks. As a quick website tech checker for triage before a call, it does the job; for exhaustive fingerprinting of obscure libraries, a larger database wins.

The CMS tells you the migration story: a WordPress detection means plugins and themes, Shopify means an ecommerce operation. Analytics maturity shows in whether they run Google Tag Manager, Segment, or Hotjar, and Stripe or PayPal flags a transactional business. Those details shape the first call more than anything on the pricing page.

It's a lightweight website technology checker, not a crawler. As a website technology finder it fetches one page's raw HTML and matches it against 25+ signature patterns, then groups the hits. It reads a single URL rather than spidering the whole site, which keeps it fast for a quick pre-call check.

Paste the homepage and click Detect stack. To check tech stack of website targets, the tool tests the HTML for framework, CMS, analytics, and payment fingerprints, then shows each with a confidence badge. It's the quickest way to find tech stack of website prospects when you only have a minute.

Yes. To find technology stack of website builders, it looks for tells like data-wf attributes for Webflow and cdn.shopify.com references for Shopify, alongside WordPress, Wix, Squarespace, and Ghost. CMS detection is its strongest category because those platforms leave loud fingerprints in the HTML.
