Tech Stack Detector
Detect the technology stack of any website
Tech-detect identifies frameworks, libraries, trackers and services on a site: React, Vue, Angular, Next.js, jQuery, Google Analytics, Yandex Metrika, Hotjar, CDNs (Cloudflare, Fastly), server types (nginx, Apache, Caddy). Uses 120+ fingerprint patterns.
What is a Tech Stack Detector?
A tech stack detector analyzes a website's HTTP headers and HTML source code to identify the technologies powering it — CMS, frameworks, JS libraries, web server, CDN, and analytics. Useful for competitive research and security audits.
The tool performs a real HTTP GET request to the target URL and applies pattern matching against 40+ technology fingerprints. Results are cached for 10 minutes to ensure fast repeated lookups.
