invisible_playwright - Undetected Playwright automation on a Firefox patched at the C++ source level, so the fingerprint is produced by the engine instead of injected into the page. On PyPI.

invisible_firefox - An open-source anti-detect browser: many identities, one patched Firefox, no subscription.

invisible_core - The pure-config engine (seed to fingerprint to prefs) both of the above run on. Zero Playwright dependency.

firefox_antidetect_patch - The patched Firefox source itself, and the binaries built from it.

Notes on how browser fingerprinting actually works, written one surface at a time: feder-cr.github.io/invisible_playwright.
