Explore what the browser exposes about you
I built a tool that reveals the data your browser exposes automatically every time you visit a website. GitHub: https://github.com/neberej/exposedbydefault Demo: https://neberej.github.io/exposedbydefault/ Note: No data is sent anywhere. Everything runs in your browser.
In plain words
This tool shows users what information their browser automatically shares with websites during visits. It's designed for anyone curious about their digital privacy, particularly developers and privacy-conscious internet users. The tool runs entirely locally in the browser, so no data leaves the user's device. It provides transparency into browser-exposed data like user agent, language settings, and other metadata that websites can access by default.
