camoufox

Camoufox is a Firefox fork built to not look like a bot. The usual approach patches fingerprints with injected JavaScript that detection scripts can watch happening. Camoufox does that work inside the browser at the C++ level, so navigator properties, screen and viewport dimensions, geolocation, timezone, locale, WebGL, and fonts report spoofed values from below the layer a page can inspect. MPL 2.0, free, and it drives from Playwright code you already wrote.

Setup is a pip install plus a browser download, then you swap the Playwright launch call. The footprint is small for a full browser, and it strips CSS animations and telemetry noise so the DOM comes out cleaner if you are feeding pages to a model.

Individuals and small teams get the whole thing free with no tier above it. The actual bill is proxies. The browser handles the fingerprint; your IP address is still your IP address, and residential bandwidth is what scales with the job.

The catch runs two ways. The README and docs are largely an ad board for proxy resellers with discount codes attached, so read those recommendations as paid placements. And this is a permanent arms race: sites update detection, you update your setup, and whether a target's terms of service allow any of it is a decision you own.
