Description
Detect the technologies a page uses. Fully local, no data leaves your browser. OpenTechCheck shows you the technology stack behind any website: frameworks, CMS, e-commerce platforms, analytics, tag managers, CDNs, servers, and programming languages - grouped by category, with version numbers where detectable. What makes it different: EVIDENCE FOR EVERY CLAIM Every detection shows the exact signal that produced it — a response header, a meta tag, a script URL, a JavaScript global. Expand any row to see the proof. Confidence grades (A–D) tell you how solid each detection is. 100% LOCAL Detection runs entirely inside your browser, against the page you already loaded. The extension makes zero network requests: fingerprints, icons, and fonts all ship in the package. No account, no tracking, no analytics, no cloud. Nothing about your browsing ever leaves your machine. OPEN SOURCE The detection engine and all 152+ technology fingerprints are open source (Apache-2.0) and community-maintained. Every fingerprint is a readable YAML file, tested in CI against fixtures captured from real sites. Wrong or missing detection? One pull request fixes it for everyone. USEFUL OUTPUT Copy the stack as plain text or export the full result — detections, versions, confidence, evidence : as JSON.
