Website Detector - Evidence-first technology detection

See what any website is built with - platform, frameworks and services - each with a confidence score and the evidence.

🔍 WEBSITE DETECTOR — Evidence-first technology detection Discover what any website is built with: its content management system, website builder, ecommerce platform, backend and frontend frameworks, analytics, marketing tools, payments, hosting, and CDN — each with a confidence score and the exact evidence behind the result. Unlike detectors that guess from a single keyword, Website Detector runs a multi-pass scan (document metadata → DOM fingerprints → resource URLs → runtime markers) and scores every technology from independent evidence groups. When a platform is reported as 100% Confirmed, you can expand the card and see exactly why: the generator tag, the asset paths, and the live runtime marker that prove it. ⚡ WHAT IT COVERS 124 carefully tested technologies across every layer of the modern web stack: content platforms and site builders, ecommerce systems, server-side frameworks and languages, client-side frameworks and UI libraries, analytics and tag managers, marketing and support widgets, payment providers, consent platforms, advertising pixels, hosting providers, CDNs, security services, and progressive web app capabilities. Detection works on production builds too, including frameworks that hide their global variables once minified. ✨ KEY FEATURES • Primary-stack view: the platform headline first, then the organized full stack • Confidence scores (Confirmed / High / Possible) with visible, expandable evidence • Version detection — shown only when actually observable, never guessed • First-party vs third-party vs embedded-widget classification • Search, category filters, confidence filters, and sorting • Save results, annotate them, and compare any two scans to see what changed • Export a PDF report, JSON, CSV, or Markdown — or copy the stack as text • Keyboard shortcuts, a toolbar count badge, and a right-click scan option • Light, dark, and automatic themes plus a compact density mode 🔒 PRIVACY FIRST — GENUINELY LOCAL • All analysis runs inside your browser. The extension makes zero network requests. • No tracking, no analytics, no external APIs, no account, no sign-in. • It scans only when you ask it to, on the page you choose. • Cookie names only, never cookie values. Query strings are stripped from evidence. Results depend on the technical signals each website exposes. "Not detected on this page" never claims "not used by this website" — that honesty is the point. Built by NHR SOFT — www.nhrsoft.com
