Detechtor AI - Website Technology Checker & Tech Stack Detector

Detechtor AI checks what any website is built with — CMS & WordPress theme detector, frameworks, analytics, CDN, tech stack.

Ever wondered what a website is built with? Detechtor AI reveals the technology behind any page you visit — in one click. Open a page, click the toolbar icon, and see the whole stack: content management systems, website builders, JavaScript frameworks, ecommerce platforms, analytics and advertising tags, CDNs, hosting providers, payment services and more. Over 160 technologies across 22 categories, with version numbers whenever they can be detected. WHAT IT DOES • One-click detection wherever you are browsing • Theme and plugin discovery on WordPress sites, listed with their versions • Evidence for every result — see the exact script, header or cookie that produced each match • A confidence score on each finding, so you know what is certain and what is inferred • Server details: IP address, status code, HTTP protocol and server software • Page details: title, description, canonical, robots meta, structured data and asset counts • Security header grade from A to F, with alerts when a server leaks software versions • Export your results to JSON or CSV • Light and dark themes, 58 interface languages • Switch it off on any domain you choose HOW IT WORKS Detechtor examines what you are already viewing — markup, script paths, response headers, cookies and JavaScript globals — then matches those signals against a fingerprint database bundled inside the extension. The scan runs in your browser. Page content, addresses and browsing history are never uploaded. PRIVACY AND ACCOUNT A Google sign-in is required. We receive your email address and basic profile only, and use them to identify your account and subscription plan. We do not monitor your browsing, sell data or show ads. Full details are in our privacy policy. PLANS The free plan covers 5 different websites per day, and returning to one you have already checked does not use another. Premium removes the daily limit. WHO IT IS FOR Developers, SEO specialists, agencies, marketers and anyone curious about how a project is put together — from competitor research to platform evaluation and pre-launch audits. Add Detechtor AI to Chrome and find out what any website is running.
