Detect what technologies, frameworks, and CMS a website uses.
What is Technology Lookup?
Technology Lookup detects the technologies, frameworks, and services used by any website. Identifies the web server, CMS, JavaScript frameworks, analytics tools, CDN, and hosting provider from HTTP headers and page content.
How to use this tool
Enter a website URL.
The tool fetches the page and analyzes headers, scripts, and meta tags.
See detected technologies grouped by category.
Identify the web server (Nginx, Apache), CMS (WordPress, Shopify), and frameworks.
Use for competitive research or technology evaluation.
Frequently asked questions
How does technology detection work?
The tool examines HTTP response headers (Server, X-Powered-By), HTML meta tags, JavaScript file patterns, CSS framework signatures, and DNS records. Each technology leaves identifiable fingerprints.
Is the detection always accurate?
Mostly, but not 100%. Some sites hide their stack by removing Server headers or using CDNs that mask the origin. Custom-built sites without common frameworks may show limited results.
Why check what technology a site uses?
Competitive research — see what successful sites in your niche use. Technology evaluation — compare options before building. Security auditing — identify potentially vulnerable components.
Can sites hide their technology stack?
Partially. You can remove Server headers, disable X-Powered-By, and use a CDN. But JavaScript frameworks, CSS patterns, and HTML structure are harder to hide completely.
