This extension is simple, useful, and impressively well-designed. It gives instant visibility into a website’s security headers without needing any extra setup, and the real-time grade makes it very easy to understand at a glance. I especially like that everything runs locally in the browser, which adds an extra layer of privacy and convenience. The interface is clean, the report is easy to read, and it feels like a reliable tool for anyone who wants a quick security check while browsing.
