## Description

Identify the technology behind any website at a glance.

Web Stack Detector analyzes a page locally to determine how its frontend is built, including its framework, UI toolkit, and build system. The toolbar icon automatically reflects the detected project, while the popup shows the detected version and the evidence used to identify it.

Everything runs locally in your browser. No page data or browsing activity is sent anywhere.
