CloakBrowser is CloakHQ’s stealth Chromium for AI agents — a drop-in Playwright/Puppeteer replacement for scrapers and computer-use loops that keep getting blocked by Cloudflare Turnstile and reCAPTCHA v3. +1,606 GitHub stars in a single day on Trending.

Why it actually passes detection

Most stealth tools — puppeteer-extra-plugin-stealth, undetected-chromedriver — inject JavaScript at runtime to lie about Canvas, WebGL, fonts, GPU. Detection vendors patched those tricks years ago. CloakBrowser does it the hard way: 32 patches against the Chromium C++ source, recompiled. Canvas, WebGL, AudioContext, font enumeration, GPU info — all rewritten at the engine level before a single byte of page JS executes. Benchmark page reports 30/30 pass, including reCAPTCHA v3 at 0.9 (a real-human score) and Cloudflare Turnstile clean. No vendor has shipped a runtime patch for “the binary is just different.”

Drop-in API for agent stacks

Same async interface as Playwright and Puppeteer — swap one import line and existing scrapers keep working. browser-use, Crawl4AI, Stagehand, LangChain, and Anthropic’s Claude computer use have all integrated it. Set humanize=True and it layers on bezier mouse curves and natural keyboard rhythm, which kills the last bit of behavioral detection. There’s also CloakMCP, an MCP server build, so Claude can drive a browser directly with no SDK shim in between. Playwright alone now gets blocked on roughly any site worth scraping — that’s the whole reason every agent framework is quietly wiring this underneath.
