Clearcote Browser v0.1.0-pre.4 (Chromium 149.0.7827.114, Windows x64)

Supersedes v0.1.0-pre.3. Same Chromium build — this release adds the missing
149.0.7827.114.manifest (the SxS version-assembly manifest) to the archive root.
Without it, chrome.exe fails to start on a clean Windows box with "the side-by-side
configuration is incorrect" (surfaced via Playwright/Puppeteer as spawn UNKNOWN).
pre.1–pre.3 shipped without it; the SDK clearcote@0.1.2 / PyPI 0.1.1 point here.

The browser binary itself is byte-identical to pre.3 (chrome.exe sha256 unchanged).

Verify (don't trust — verify)

The pinned signing-key fingerprint is CA96F185 F96A 693A EDB3 AC1F CB00 D851 B7A8 6B0F
(also in README / VERIFY.md). Confirm the key's fingerprint
equals that value, then check the signature.

gpg --with-fingerprint --show-keys clearcote-signing-key.asc   # must equal the pinned fingerprint
gpg --import clearcote-signing-key.asc
gpg --verify SHA256SUMS.txt.asc SHA256SUMS.txt                  # Good signature
sha256sum -c clearcote-149.0.7827.114-windows-x64.zip.sha256    # OK
unzip -p clearcote-149.0.7827.114-windows-x64.zip chrome.exe | sha256sum   # matches above

Quickstart (Playwright drop-in)

from playwright.sync_api import sync_playwright
with sync_playwright() as p:
    b = p.chromium.launch(
        executable_path=r"C:\clearcote\chrome.exe",
        args=["--fingerprint=seed-123", "--fingerprint-platform=windows"],
    )
    b.new_page().goto("https://abrahamjuliot.github.io/creepjs/")

Or via the SDK: npm i clearcote / pip install clearcote then launch() (auto-downloads + verifies this build).

Caveats

  • Pre-release / not exhaustively stealth-validated across all detection suites on real Windows.
  • is_official_build=false — matches the published config/args.gn; not yet a stable official build.
  • proprietary_codecs=true — H.264/AAC enabled; mind redistribution terms.
  • Per-eTLD+1 farbling (canvas/WebGL/audio) + WebRTC leak controls are engine-level in this build.
