TechPeek

TechPeek reveals what a website is built with — one click, no setup required.

Open TechPeek on any website to see the frameworks, libraries, CSS tools, content management systems, analytics platforms, and hosting providers powering that site.

Results are organized by category so you can quickly understand a site's full technology profile. Version numbers are shown where detectable.

TechPeek works by scanning script tags, stylesheets, window globals, and DOM fingerprints locally in your browser. No data is sent to any server.

Note: Websites that heavily bundle and obfuscate their code may return limited results. This is a known limitation of all browser-based technology detection tools.

Lightweight. No ads. No data collection. Everything runs on your device.
