itbrowser-net/undetectable-fingerprint-browser — reverse-engineered prompt

Build me an open source Chromium based fingerprint browser for legitimate testing and privacy research. I want to run it locally, create a browser fingerprint profile as a JSON file, then launch Chromium with that profile so websites see a consistent test device instead of my real one.

It should let me control the normal signals sites check, like canvas, WebGL, audio, fonts, screen size, CPU cores, memory, time zone, language, mobile touch settings, GPS and WebRTC leaks. Please make the settings realistic together so the profile doesn’t look mismatched. Add proxy support and a way to inject local JavaScript for controlled tests.

I also need it to work with Puppeteer and Playwright by pointing automation at the custom browser, with remote debugging enabled. Include a simple command line tool to generate fingerprints, launch with a chosen fingerprint, and clear instructions for building from source or using a prebuilt release. Keep it for legal security research and QA only.
