Detect the technology stack of any website
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.
