Shipped this project!
I built Imprint, a browser fingerprinting tool using pure HTML, CSS, and JS! It works completely client-side, so no data is saved, and you can view information about more than 15 different metrics exposed by your browser. You can export this information as a .json file, and you are also given automatically generated
suggestions on how to prevent being profiled.
There are also modals for the legal policy, changelog, and feedback form. You can also click on any of the metrics to copy them to the clipboard!
