What is CloakBrowser?
CloakBrowser is a stealth Chromium build for browser automation. Instead of patching config or injecting JavaScript, it modifies fingerprints in Chromium's C++ source, so anti-bot systems see an ordinary browser.
It works as a drop-in replacement for Playwright and Puppeteer in Python and JavaScript, installs with pip or npm, and has a humanize option for human-like mouse, keyboard and scrolling. A free binary is available, with a paid Pro tier.
