Website Technology Detector - Tech Stack

Discover a website’s technology stack and inspect the evidence behind detected results.

Website Technology Detector helps you inspect the technology signals visible on the current webpage. Open the extension on a site to see detected tools with the evidence behind each match. The report brings together page-level technology, security-header, privacy, performance, network, SEO and accessibility observations. You can review earlier scans, compare changes and export a summary as JSON or CSV. Detection is based on signals that the browser can observe, such as page assets, metadata, cookies and response headers. A result is not a guarantee that a technology powers the entire site, and technologies that hide their signatures may not be identified. Performance and audit scores are local estimates, not a replacement for a full professional audit. Reports and scan history stay in your browser. DNS lookups for the scanned hostname use Google Public DNS. The extension does not send scan history to the developer.
