Tech Stack Detector
Detect the technologies a website is built with, from any URL.
Detect a Website's Tech Stack
Enter a URL and this tool fetches the page and inspects its HTML and response headers for the fingerprints that frameworks, content systems, analytics, and hosting platforms leave behind. The detected technologies are grouped by category.
What it can spot
- Frameworks like Next.js, Nuxt, Gatsby, and Angular
- Libraries such as React, Vue, and jQuery
- CMS and builders: WordPress, Shopify, Wix, Webflow
- Analytics, payments, hosting, CDNs, and web servers
How confident is it?
Detection is based on visible signatures — asset paths, global variables, meta tags, and HTTP headers. It is strong evidence rather than absolute proof, since sites can hide or proxy these signals.
Where the clues come from
Most stacks reveal themselves: Next.js ships a /_next/ path and __NEXT_DATA__, WordPress serves /wp-content/, and servers announce themselves in the Server and X-Powered-By headers. This tool reads those public signals — the same ones any visitor's browser receives.
Use it for research
Tech detection is great for competitive research, lead qualification, compatibility checks, and satisfying plain curiosity about how a site is built. It only reads what the site already exposes publicly.
