Brief

CloakBrowser is a MIT‑licensed stealth Chromium (pip install, ~200MB) that the author says achieves human-like anti-bot fidelity — 0.9 on reCAPTCHA v3 versus stock Playwright's 0.1 — by patching Chromium's C++ in 16 spots (canvas, WebGL, audio, fonts, hardwareConcurrency, GPU strings, WebDriver flag, TLS fingerprint). It claims to pass 14/14 detection tests, auto-resolve Turnstile, and replace commercial $200–$500+/month stealth browsers or costly custom builds.

Why it matters

CloakBrowser (post by @hasantoxr, published 2026-05-12) is a stealth Chromium that scores 0.9 on reCAPTCHA v3, passes 14/14 bot-detection tests, auto-resolves Cloudflare Turnstile, reportedly beats FingerprintJS and BrowserScan, and is a one-line drop-in Playwright replacement.

Key details

  • The project is 100% open-source under the MIT license, distributed via pip as a ~200MB binary; the author says it patches Chromium's C++ in 16 places (canvas, WebGL, audio fingerprint, fonts, hardwareConcurrency, GPU vendor strings, WebDriver flag, TLS fingerprint) so detection sites see a 'real browser'.
  • Author contrasts costs: Bright Data scraping browser ~$500+/month, Browserless stealth ~$200+/month, custom anti-detect builds ~$10K+ engineering — CloakBrowser is presented as a low-cost alternative installable with a pip command.
Source evidence

I'm done paying $500 a month for anti-detect browsers after finding this.

It's called CloakBrowser. A stealth Chromium that scores 0.9 on reCAPTCHA v3 (same as a real human) and passes 14 out of 14 bot detection tests.

  • Auto-resolves Cloudflare Turnstile
  • Beats FingerprintJS and BrowserScan
  • TLS fingerprint identical to real Chrome
  • Drop-in Playwright replacement (one line swap)

100% Opensource. MIT License.

What you usually pay for vs CloakBrowser:

Bright Data scraping browser → $500+/month
Browserless stealth tier → $200+/month
Custom anti-detect builds → $10K+ engineering

CloakBrowser → pip install, 200MB binary, done.

The reason it actually works:

Most stealth libraries (playwright-stealth, undetected-chromedriver, puppeteer-extra) inject JavaScript or tweak flags. Every Chrome update breaks them. Antibot systems detect the patches themselves.

CloakBrowser patches Chromium's C++ source code in 16 places. Canvas, WebGL, audio fingerprint, fonts, hardware concurrency, GPU vendor strings, WebDriver flag, TLS fingerprint.

All compiled into the binary. Detection sites see a real browser because it is a real browser.

Stock Playwright scores 0.1 on reCAPTCHA v3. CloakBrowser scores 0.9.

Same code. Same API. One import change.
