Fully open-sourced, perfect for agentic browsing, works with Vercel's agent-browser and playwright.

I've been building browser automation agents with Playwright and the detection cat-and-mouse game is real. The C++ level overrides are interesting but I'm curious how this holds up against Cloudflare's latest checks - they're not just looking at navigator properties anymore, they're timing canvas operations and checking for inconsistencies in the rendering pipeline. Have you tested this against any real-world bot detection beyond the basic fingerprinting libs?

Just ran evals on a few detectors, and clark-browser passed live stealth checks on Cloudflare smoke, SannySoft, BrowserLeaks Client Hints, and WebGL.
