Description
I built a tool that reveals the data your browser exposes automatically every time you visit a website.GitHub: https://github.com/neberej/exposedbydefaultDemo: https://neberej.github.io/exposedbydefault/Note: No data is sent anywhere. Everything runs in your browser.

Could you build this?
Yes This is a single-page client-side web application that reads standard browser APIs (navigator, screen, WebGL) and displays the collected metadata in a dashboard.
Discussion
20 comments analyzed.
Competitors mentioned: amiunique.org, Cover Your Tracks (EFF tool), Brave browser
Concerns raised: Fingerprint ID changes on every refresh, making results unreliable, Includes unstable features like canvas/audio that fluctuate between reloads, Lacks representative population dataset for accurate uniqueness comparison, Poor visualization and interpretation of results for users, iOS version detection inaccurate (showing iOS 18.7 for iOS 26)
Feature requests: Show distribution/density plots of fingerprint values, Add visualization comparing user fingerprint to population, Let users adjust settings and preview improved fingerprint results, Only use stable fingerprint features, not fluctuating ones, Suggest specific changes users should make

Same idea, different domain
Nobody's really built a observability & eval tool for Media & entertainment yet.
