Add Platform Checker to Chrome from the Chrome Web Store. No account required.
Visit any website as you normally would. The extension works automatically in the background.
Click the extension icon to see all detected technologies organized by category.
Technologies are detected automatically as you browse — no need to copy and paste URLs.
Results are grouped into clear categories like frameworks, CMS, analytics, hosting, and more.
See the number of detected technologies at a glance with the toolbar badge counter.
We only analyze publicly visible page content. No tracking, no personal data collection.
Where possible, the extension identifies the specific version of each technology being used.
No subscription, no account required. Install and start detecting technologies immediately.
Join developers and product teams who use Platform Checker to stay on top of web technologies.
