Headed launches default to no_viewport, so page.viewport_size is None and
human scroll raised "Viewport size not available". Fall back to live
window.innerWidth/innerHeight. Covers Playwright (py sync/async, JS) and
Puppeteer paths.
Replace the same-origin checksum with a detached Ed25519 signature
(SHA256SUMS.sig) verified against a pinned public key before extraction,
closing #308: a compromised download mirror can no longer certify a
tampered binary. The signed manifest also binds the release version,
rejecting a forced downgrade to an older signed build.
Verification is mandatory and non-bypassable on the official download path;
custom CLOAKBROWSER_DOWNLOAD_URL mirrors keep the legacy skippable checksum.
Silent auto-update is preserved for everyone because only a constant public
key is pinned, not per-version hashes. Older installed wrappers are
unaffected — the version= line is ignored by their checksum parser.
Python uses cryptography; JS uses node:crypto. Adds tamper, downgrade, and
fail-closed tests in both languages.
Headed launches applied a fixed emulated viewport on top of the real
browser window, yielding outerWidth < innerWidth (an impossible window).
Default headed new_page()/new_context() to no_viewport so the page tracks
the real window; headless keeps a deterministic viewport. Covers Python
launch/launch_context/launch_persistent_context (+async) and the JS
Playwright/Puppeteer wrappers. Explicit viewport still honored.
Patchright scored identically to plain Playwright on reCAPTCHA v3 (the
binary handles stealth at C++ level) while breaking proxy auth and
add_init_script (#27). Removed the backend param, CLOAKBROWSER_BACKEND
env var, the patchright extra, and the two backend-specific tests.
Stock Playwright is now the only backend.
Windows zip extraction interpolated archive/dest paths directly into the
PowerShell -Command string. A single quote in the path (e.g. a Windows
account like C:\Users\O'Brien) closed the string literal early, breaking
extraction and creating a code-injection shape. execFileSync guards the
OS-shell boundary but not the PowerShell interpreter inside.
Pass both paths via env vars ($env:CB_ARCHIVE / $env:CB_DEST) so
PowerShell reads them as data, never as code. No escaping needed.
Python wrapper unaffected (zipfile module + argv).
Zero typing_delay so the '!'-uses-CDP assertion no longer races the
5s default timeout under random thinking-pauses + CI load. Test only
checks which chars route through CDP, not timing.
Sideloaded Widevine works on the first launch of a persistent context
instead of needing a manual two-launch hint-file workaround. The wrapper
writes Chromium's CDM hint file into the profile before launch when a
WidevineCdm directory is present next to the binary.
- New cloakbrowser/widevine.py and js/src/widevine.ts: resolve a sideloaded
CDM (CLOAKBROWSER_WIDEVINE_CDM env var, else next to the binary) and seed
the hint file. Linux only; no-op elsewhere. CLOAKBROWSER_WIDEVINE=0 disables.
- Never bundles/downloads/copies the CDM (proprietary); seeds only when the
user-provided CDM is already present.
- Wired into launch_persistent_context[_async] and launchPersistentContext.
- README + js/README: Widevine / DRM section, env vars, FPJS tradeoff note.
- Tests: tests/test_widevine.py, js/tests/widevine.test.ts, persistent-context
integration assertions.
Mirror the JS fix from #303 in the sync and async Python actionability
checks: compute and apply the iframe coordinate offset before
elementFromPoint, and fail open when the check itself cannot run. Add
fail-open regression tests for both Python and JS.
Frame-level methods (click, dblclick, hover, dragAndDrop) passed the raw
timeout to each sequential operation independently, causing 3x actual
wait time when elements don't exist. ElementHandle methods had a similar
2x issue between actionability and pointer-events checks.
Port the deadline + remainingMs() pattern already used by page-level
methods. Also fix bot detection test selector after site added a hidden
duplicate submit button.
Bypass Playwright's CDP Fetch.authRequired interceptor for authenticated
HTTP proxies by passing inline credentials via Chrome's --proxy-server
flag. Chrome sends Proxy-Authorization preemptively, avoiding the 407
round-trip that breaks on some proxies and Google domains (#182).
Gated on platform (linux-x64, windows-x64) and binary version >= 146.0.7680.177.5.
Unsupported platforms fall back to Playwright's proxy dict.
Puppeteer falls back to page.authenticate() on unsupported platforms.
Expose userDataDir support via launchPersistentContext() for
cloakbrowser/puppeteer, matching the existing Playwright API.
Includes proxy auth, geoip, and humanize support.
Remove dead null checks, document CLOAKBROWSER_GEOIP_TIMEOUT_SECONDS
env var, credit contributor.
Fix review findings:
- Use timeout-bounded resolve_proxy_exit_ip in _resolve_webrtc_args
- Add missing timeout handler on tunneled HTTPS request in JS
- Reject nan/inf in Python timeout parsing (parity with JS)
- Recompute deadline after CONNECT succeeds in JS proxy tunnel
- Extract HumanActionOptions type alias to replace ~40 inline copies
- Frame check/uncheck: let isChecked errors propagate instead of silently clicking non-checkbox elements
- SOCKS5 credential log: console.debug → console.info (parity with Python logger.info)
- Add contributors to README
The humanize layer hardcoded timeout=2000ms for element lookups, causing
locator.click() and page.click() to fail instantly instead of retrying
for 30s like standard Playwright. Aligned all defaults to 30000ms across
Python sync/async, JS Playwright, and JS Puppeteer paths. Bumped the
outer retry sleep from 200ms to 500ms for DOM mutation settle time.
Chromium's --proxy-server parser truncates passwords at '=' and other
special chars, causing SOCKS5 auth to silently fail and fall back to
direct connection. The dict path already encoded creds; now the string
path does too. Idempotent: pre-encoded input stays encoded.
Python: add async counterpart to launch_context(). Forwards all kwargs to
browser.new_context() — enables storage_state, permissions, extra_http_headers,
etc. without needing a persistent profile folder.
JS: launchContext() and launchPersistentContext() silently dropped unknown
options. New contextOptions field in LaunchContextOptions is spread into
newContext() to forward arbitrary Playwright context options (e.g.
storageState, permissions, geolocation).
Route SOCKS5/SOCKS5h proxies via --proxy-server Chrome arg instead of
Playwright's proxy dict (which rejects SOCKS5 with credentials).
Handles string URLs, Playwright dicts, IPv6, bypass lists.
SOCKS5 geoip exit IP resolution uses socks-proxy-agent (optional peer
dep). Falls back to DNS if not installed.
CLI args like --fingerprint-locale were passed as raw passthrough args
to Chrome, missing the companion --lang flag that build_args() normally
adds. Caused Intl API to default to en-US while navigator.language
showed the correct locale — a detectable mismatch.
Fixes#130
Node 22 ships npm v10 which lacks OIDC support. The upgrade step was
removed in 02359f6 but is required for provenance-based publishing.
Pin to npm@11 instead of @latest to avoid future breakage.
Remove --disable-blink-features=AutomationControlled (dead, binary handles
navigator.webdriver at source level) and hardcoded GPU vendor/renderer flags.
Binary auto-generates diverse GPU profiles from fingerprint seed. Improves
fingerprint diversity -- previously every user shared the same GPU string.
Bump to v0.3.21.
viewport=None now disables viewport emulation via Playwright's
no_viewport=True, matching the JS wrapper's viewport: null behavior.
Uses a sentinel to distinguish "not provided" from explicit None.

Two ways to spoof WebRTC ICE candidate IPs:
1. --fingerprint-webrtc-ip=auto in args: resolves proxy exit IP via
HTTP call through the proxy (ipify.org). No extra deps needed.
2. geoip=True: auto-injects the flag for free (exit IP already
resolved during timezone/locale lookup, zero extra network cost).
Explicit IP (--fingerprint-webrtc-ip=1.2.3.4) also supported.
User-provided values always take precedence.
Python + JS wrappers, README docs, tests.
- Move `import websockets` to top-level (guaranteed by [serve] extra)
- Add --data-dir flag with smart default (Docker → /tmp/cloakserve, bare metal → ~/.cloakbrowser/cloakserve)
- Store launch params (tz/locale/proxy) on ChromeProcess for conflict logging
- Enhance GET / to return per-process detail (pid, port, seed, connections, config)
- Add connection refcounting in WS handlers for status visibility
- Add first-launch-wins note to README
- Add tests for data-dir, Docker detection, and connection tracking
Spawns a separate Chrome process per unique fingerprint seed, all behind
a single port (9222). Clients specify seeds and fingerprint params via
query string on the CDP URL:
connect_over_cdp("http://host:9222?fingerprint=12345&timezone=Asia/Tokyo")
Supports all --fingerprint-* flags as query params, geoip=true for
auto timezone/locale from proxy IP, and proxy= for per-process proxies.
- Rewrite bin/cloakserve from 57-line wrapper to aiohttp CDP multiplexer
- Add ChromePool with per-seed process management and port allocation
- Bidirectional WebSocket proxy for CDP traffic
- URL rewriting for /json/version, /json/list, and WS paths
- Rename _build_args -> build_args, _maybe_resolve_geoip -> maybe_resolve_geoip
- Add aiohttp + websockets to serve optional deps
- Dockerfile installs .[serve] extras
- Add 20 unit tests for cloakserve (param parsing, CLI args, URL rewriting)
Pin all 22 action references across ci.yml, publish.yml, and
attest-release.yml to immutable commit SHAs. Mutable tags can be
force-pushed by attackers (cf. TeamPCP supply chain campaign).
Add Dependabot for github-actions to get weekly PRs when pinned
actions have new versions.
- Bump wrapper version to 0.3.17 (Python + JS)
- Update PLATFORM_CHROMIUM_VERSIONS: windows-x64 109.2 → 159.7
- Update patch counts in platform tables (Linux 33, Windows 33)
- Add Linux arm64 to JS README platform table
- Update CHANGELOG with all changes since v0.3.16
Headed mode (all platforms): Chromium's GPU blocklist disables WebGL on
software GPUs in Docker/VNC/Xvfb. Flag lets SwiftShader serve WebGL.
Harmless on real GPUs. Headless unaffected. Ref #56.
Windows (all modes): GPU blocklist also blocks WebGPU for the Microsoft
Basic Render Driver. Dawn's adapter_blocklist bypass alone isn't enough.
Add examples/integrations/ with tested examples for browser-use, Crawl4AI,
Scrapling, LangChain, Selenium, undetected-chromedriver, and agent-browser.
Add js/examples/stagehand.ts for Stagehand (TypeScript).
README: new "Framework Integrations" subsection with two integration
patterns (direct binary launch vs CDP connect) and table linking all 8 examples.

Verify that HTTP errors (429, 503, etc.) from cloakbrowser.dev
correctly trigger GitHub Releases fallback for both binary and
checksum downloads. Also test that custom CLOAKBROWSER_DOWNLOAD_URL
disables fallback, and both-sources-fail returns gracefully.
Adds install, info, update, and clear-cache subcommands with visible
download progress. Python: `python -m cloakbrowser install`. JavaScript:
`npx cloakbrowser install`. Useful for Dockerfiles where silent
first-use downloads are hard to debug. Closes#43.
- Add cosign verify command to README Security section for Docker image verification
- Add GitHub deployment environments (pypi, npm, docker) to publish workflow for sidebar status tracking
- Simplify downgrade instructions: version-pinned pip/npm/docker instead of manual binary paths
- Improve troubleshooting section with headings and dividers for readability
- Update Latest section to v0.3.12 with new binary features
- Remove locale and timezone_id from Playwright context kwargs (CDP)
- Pass timezone via --fingerprint-timezone binary flag (process-wide)
- Pass locale via --lang + --fingerprint-locale binary flags
- Accept both timezone and timezone_id param names silently (no deprecation)
- Update all wrapper tests to verify binary args, not CDP context params
- publish.yml: automated PyPI/npm/Docker on v* tag push; OIDC trusted publishing for PyPI/npm; Docker signed with Cosign keyless + provenance attested
- attest-release.yml: manual workflow to attest binary release assets via Sigstore (actions/attest-build-provenance@v2)
- pyproject.toml: add dev extras (pytest, pytest-asyncio)
Binary: fix detection regression (#16), fix fingerprint consistency in offline audio rendering.
Wrapper: bump version to 0.3.10, update Linux binary version to 145.0.7632.159.2.
Add bin/cloakserve — launches stealth Chromium with remote debugging
enabled so users can connect via connect_over_cdp() from the host.
Uses socat to forward 0.0.0.0:9222 to Chrome's localhost-only CDP port.
Usage: docker run -d -p 127.0.0.1:9222:9222 cloakhq/cloakbrowser cloakserve
Tested: all stealth checks pass via CDP, bot.sannysoft.com 54/54,
reCAPTCHA 0.9, zero detection regressions.
Bump version to 0.3.9. Extract shared buildArgs into js/src/args.ts (DRY),
guard console.debug behind DEBUG=cloakbrowser env var, strengthen caplog assertion.
