CloakBrowser v0.3.0 — Chromium 145, 25 patches, 30/30 tests

[Cloak-HQ]

Hey everyone 👋

For those just finding us — CloakBrowser is a stealth Chromium binary with fingerprints modified at the C++ source level. Drop-in replacement for Playwright (Python & JS) and Puppeteer. Not config flags, not JS injection — compiled into the binary.

We launched on Reddit 10 days ago and the response has been wild. Thank you to everyone who starred, tested, filed issues, and requested features. A lot of what shipped since v0.1.0 came directly from community feedback.

What's in v0.3.0

• Chromium 145 — latest stable, up from 142
• 25 source-level patches (up from 16) — screen, audio, WebGL, device memory, and more
• Full stealth audit — every patch reviewed for detection vectors, multiple fixes shipped
• SHA-256 checksum verification on binary downloads
• CDP hardening — audited and patched known automation detection vectors
• Timezone & locale from proxy IP — launch(proxy="...", geoip=True)
• macOS support — Apple Silicon and Intel, both platforms
• JavaScript wrapper — npm install cloakbrowser, works with Playwright and Puppeteer

Still passes 30/30 detection tests. 0.9 reCAPTCHA v3 score. Cloudflare Turnstile, FingerprintJS, BrowserScan — all pass.

Get started

pip install cloakbrowser

from cloakbrowser import launch

browser = launch()
page = browser.new_page()
page.goto("https://protected-site.com")
browser.close()

Or JS:

npm install cloakbrowser playwright-core

import { launch } from 'cloakbrowser';
const browser = await launch();

What's next

• macOS v145 binary builds (Apple Silicon + Intel)
• Built-in proxy rotation
• Keeping up with Chromium releases

Using Discussions

This is the place for:

• Questions — setup, config, detection issues, proxy tips
• Show & tell — share what you're building with CloakBrowser
• Feature requests — what would make this more useful for you?
• Bug reports → still use GitHub Issues for those

If you've tested CloakBrowser against a site and have results (pass or fail), we'd love to hear about it. Real-world detection data helps us prioritize patches.

Hi! Really waiting windows native release!

Your project looks great to browser automation for testers and every other developer that works with web testing!

Really good wishes

Thanks for the kind words!

Windows is on the roadmap. Once we stabilize the v145 builds across Linux and macOS, Windows is next in line.

In the meantime, you can run CloakBrowser on Windows today using Docker (WSL2). The Linux binary works perfectly in a container, and you get the full stealth experience.

We'll announce it here when the native Windows build drops. Star the repo and hit Watch to get notified!

Windows native support just landed in v0.3.4. Binary auto-downloads on Windows now.

pip install cloakbrowser --upgrade

This is the first Windows release, so if you run into anything, open a GitHub issue and we'll sort it out.
