Chromium v150.0.7871.114.3 — Stealth Build (Pro)

CloakBrowser Pro — Chromium 150.0.7871.114.3

The Pro line moves to Chromium 150, available on all five platforms at once — Linux x64, Linux arm64, Windows x64, macOS arm64, and macOS x64.

With a valid Pro license, your wrapper picks up this build automatically within the hour. Get Pro at https://cloakbrowser.dev.

What's changed in the binary

71 source-level patches. A full rebase onto the Chromium 150 line with the complete patch set ported forward, plus a round of coherence work. Moving from the previous stable, this covers everything since 148.0.7778.215.5.

• Closer alignment with a real Chrome install across speech and language profiles, font handling, storage reporting, Windows system colors and selection rendering, and graphics parameters.
• Coherent Apple Silicon profiles — chip, memory, screen, display scaling, and graphics limits are chosen together as one plausible Mac rather than independently, and display characteristics hold together across headed and headless launches.
• Puppeteer fix — navigator.userAgentData now reports coherent brands and versions under puppeteer-core, which previously could come back blank.
• More self-consistent identities — values a real browser reports consistently now stay consistent across repeat reads and across launch modes.
• The reported Chrome version tracks real Chrome, independent of the version we build from.
• Clearer license failures — the license gate exits with a distinct code per denial reason, surfaced as a specific CloakBrowserLicenseError.

If a site regresses on this build

You're never stuck. If something that worked before breaks on 150, pin the previous stable and keep running — then open an issue telling us exactly what broke so we can fix it fast:

launch(license_key="cb_...", browser_version="148.0.7778.215.5")

CLOAKBROWSER_VERSION=148.0.7778.215.5   # env var, any language

Remove the pin once the fix ships to return to the latest.

Chromium v148.0.7778.215.5 — Stealth Build (Pro)

CloakBrowser Pro — Chromium 148.0.7778.215.5

The latest Pro build — the biggest fingerprint update yet — now on Windows and Linux (x64 + arm64). macOS follows shortly.

With a valid Pro license, your wrapper picks up this build automatically within the hour. Get Pro at https://cloakbrowser.dev.

What's changed in the binary

• More common, more coherent hardware identities — each --fingerprint seed is built from the most common real-world hardware values (screen, GPU, RAM, CPU cores, color depth, fonts, audio), chosen together so they form a popular, self-consistent device with no internal contradictions.
• Deeper, more consistent Windows persona — expanded and localized font populations, tighter graphics/display alignment, and seed-coherent screen, color depth, and audio across browser- and OS-level signals.
• Expanded NVIDIA GPU profiles, each matched to a plausible CPU, RAM, and screen combination.
• Window and screen geometry coherence in both headed and headless modes (pairs with the wrapper's new maximized-window default).
• Greater WebGL and WebGPU realism, including consistent behavior under timing inspection.
• Cleaner proxy behavior — better proxy-auth handling and less proxy-specific reload and cache leakage.
• New pass-through debug mode (--fingerprint=off) and a third-party-cookie compatibility flag (--fingerprint-allow-3p-cookies).
• Runtime Pro license sessions — privacy-preserving groundwork for future session-limit enforcement (--license-through-proxy opts these calls onto your proxy, Linux only for now).

New in the wrapper (v0.4.8)

• geoip works without a proxy — on a direct connection geoip=True resolves your own public IP for timezone and locale.
• 132-country locale coverage (up from 50).
• Maximized window by default on the newest builds, so window and screen geometry stay consistent.

pip install -U cloakbrowser        # Python
npm update cloakbrowser            # JavaScript
dotnet add package CloakBrowser    # .NET

Chromium v148.0.7778.215.3 — Stealth Build (Pro)

CloakBrowser Pro — Chromium 148.0.7778.215.3

The latest Pro build, with fingerprint and consistency improvements across Linux, Windows, and macOS (Apple Silicon + Intel).

With a valid Pro license, your wrapper picks up this build automatically within the hour. Get Pro at https://cloakbrowser.dev.

What's changed in the binary

• Fingerprint refinements and cross-platform alignment so every platform reports a coherent, real-looking profile.

New in the wrapper (v0.4.4)

• Version pinning / rollback — pin an exact Chromium build with browser_version= (browserVersion in JS, BrowserVersion in .NET) or the CLOAKBROWSER_VERSION env var. If a new build ever regresses on one of your sites, roll back to the previous one instantly. Works for Free and Pro.
• Per-OS version resolution, so a release for one platform no longer affects the others.

npm update cloakbrowser            # JavaScript
dotnet add package CloakBrowser    # .NET

Chromium v148.0.7778.215.2 — Stealth Build (Pro)

Stealth Chromium Build: CloakBrowser Pro

The first CloakBrowser Pro build: Chromium 148.0.7778.215.2 with 59 source-level fingerprint patches.

Anti-bot vendors fingerprint your Chromium version. Running 148 keeps you matched to the current Chrome wave instead of standing out on an aging build.

v146 stays free forever on GitHub Releases and the wrapper (Python + JS) stays MIT. Pro is the latest build; the previous major version is always free. When the next major Chromium ships, v148 rolls down to free.

Early-adopter pricing is live → https://cloakbrowser.dev

What's new in 148

• Rebased the full patch set across two Chromium major versions (146 → 147 → 148), re-applying every patch to current Chromium internals, so your browser version matches what real Chrome users run today
• Cross-API fingerprint consistency improvements for Chromium 148 profiles
• WebRTC fingerprint hardening: network signals matched to real Chrome
• Font metric alignment for Windows profiles via the opt-in --fingerprint-windows-font-metrics flag (requires Windows fonts installed)
• macOS now available — Apple Silicon and Intel, with native real-GPU and locale handling

Install

export CLOAKBROWSER_LICENSE_KEY=cb_xxx   # Pro: latest build auto-downloads
pip install cloakbrowser                 # Python
npm install cloakbrowser                 # JavaScript

No key → launch() keeps using the free v146 binary, exactly as before.
