Add a preview release channel system to all wrappers (Python, JavaScript, .NET),
allowing users to opt into newer binary builds before they go stable.
- Python: preview/stable channel resolution in download, launch, CLI
(install, update, clear-cache), and license validation
- JavaScript: preview/stable channel in CLI, launch, license, and config
- .NET: preview/stable channel in CLI, license, diagnostics, and config
- All wrappers: channel fallback indicator, auto-update gate,
CLOAKBROWSER_RELEASE_CHANNEL env var support
- Harden channel resolution: reuse the resolution sidecar on offline lookups,
defensive marker/JSON parsing, atomic version-marker writes, a launch-time
preview-to-stable fallback notice, channel-aware info download URL, and
Python/JS/.NET parity for the fallback default
- Binary 150.0.7871.114.4 changelog (Linux x64 + arm64)
- Updated READMEs, CHANGELOG, and tests for all wrappers
Adds ChromePool.terminate_seed() + a close route that tears down one seed's
Chrome immediately and frees its slot, instead of waiting out the idle timeout.
Profile is preserved (goes through _cleanup_process). Idempotent.
Node derives Host from the proxy hostname unless set explicitly; strict
backconnect proxies reject the mismatch, silently falling back to the
gateway's geo instead of the real exit IP.
cloakbrowser login gets a free key via GitHub sign-in (or saves a paid key); logout reverts. Launch banner and info are now tier-aware (keyless / free / pro). A free key drops any version pin so it always gets the latest build (server force-serves latest; a pinned manifest would fail checksum). Python, JS, and .NET kept in sync. README documents the free tier + commands.
A raw --fingerprint-timezone/--lang/--fingerprint-locale in args is now
promoted to an explicit value in maybe_resolve_geoip, so geoip only fills
the values the user did not set. Mirrors the timezone=/locale= param path.
Python, JS, and .NET, with tests.
zsh globs the unquoted bracket, so a user copy-pasting the printed
install hint hits a shell error. Quote it in both messages; update the
test that pinned the old string.
geoip.py used Path.rename which cannot overwrite on Windows, so a stale
DB never refreshed and every launch re-downloaded ~70 MB in a loop. No
lock meant concurrent launches each fired their own download.
- Python: os.replace + threading.Lock (initial + background paths)
- .NET: File.Move(overwrite) + SemaphoreSlim guard
- JS: shared in-flight promise (rename already overwrites)
- tests: overwrite + concurrent single-download coverage
pyproject: bump classifier to Production/Stable
Points the READMEs at 150 as the latest Pro binary (71 patches, all five
platforms) and bumps the Pro major in the launch banner and the info
upgrade hint across Python, JS, and .NET.
A Pro license now gets a "Sessions: N seats in use" line, answering
"how many sessions do I have running?" without asking support.
Never cached (a cached count is a wrong count), skipped under --quick to
keep `info` network-free, and prints "unavailable" rather than a made-up
number when the count cannot be determined.
Python, JS and .NET.
The Pro binary exits with a distinct code per license failure; the wrappers ignored it, so a user got a bare "browser closed" error with no reason.
Add CloakBrowserLicenseError plus a launch-error parser that maps the exit code to a clear message, mirrored across the Python, JS, and .NET wrappers. Non-license failures pass through unchanged.
Route authenticated HTTP/HTTPS proxies through the browser's native proxy
authentication only on binaries that support it, resolved per platform and
binary version via a capability gate (sibling to the existing viewport and
window-geometry gates). Older binaries, including the free macOS and ARM
builds, fall back to the standard Playwright proxy path instead of emitting
credentials the binary cannot parse, so authenticated proxies keep working on
macOS and ARM instead of silently failing. Applied across the Python,
JavaScript, Puppeteer, and .NET wrappers.
With humanize=True, Locator/frame actions on an element inside an iframe
(frame.locator("#btn").click(), fill(), hover(), the frame.click(...)
equivalents) raised ElementNotAttachedError because the humanize layer
resolved every selector against the main frame. Route sub-frame locators
and frame-level actions through the owning frame's own document, keeping
humanized mouse motion inside the iframe; native fallback when the box
can't be read or the frame is detached. Python only (JS and .NET were
already frame-correct).
Adds mocked routing unit tests (sub-frame -> owning frame, main-frame ->
page, unpatched -> native), the human_click arg-order + _frame_fill
fallback guards, and @slow real-binary iframe integration tests.
Entry-point guard compared import.meta.url to an unresolved process.argv[1];
Node resolves import.meta.url through symlinks but argv[1] stays as invoked,
so npm/pnpm/npx bin symlinks never matched and no subcommand ran. Realpath
the invoked path before comparing.
Free-tier launch banner and 'cloakbrowser info' upgrade hint now advertise
the 7-day free Pro trial (Chromium 148) across Python, JS, and .NET; same
CTA added to both READMEs. Also surface binary verification failures verbatim
instead of falling back to a cached build (transient-only fallback).
info now shows the cached build that will launch AND the server's latest
Pro version on separate lines, so the two can no longer silently diverge
(a customer saw info report latest while launch ran a stale cache).
- Pro version resolution: unpinned launch prefers the server latest when it
is newer than or replaces a missing cached build, else stays on cache;
advances the version marker so info and later offline launches match.
- update command is license-aware: a valid Pro key updates the Pro binary,
everyone else updates free.
- Replace the fire-and-forget Pro background update thread with a foreground
rate-limited check (one network call/hour), honoring CLOAKBROWSER_AUTO_UPDATE=false.
- A valid Pro license never falls back to the free binary: get_effective_version
returns None when no Pro build is cached; resolution fails loudly instead.
- Tampering signal (BinaryVerificationError) surfaces verbatim on the unpinned
upgrade path — the cached-Pro fallback is only for transient download failures.
- get_effective_version(pro) requires the binary be executable, so info can't
report a build launch would reject.
- info --quick stays network-free (skips the server latest lookup); prints a
'not downloaded yet' line instead of 'None' when offline with no cache.
- Align the JS .last_update_check marker to seconds (Python/.NET parity).
- Mirror across Python, JS, and .NET wrappers; add update/CLI tests.
Windows font check now covers the full 8-font set (adds the two monospace
fonts) and reports a strict N/8 count; the launch-time warning fires on any
incomplete set, not just when none are present. Adds a separate Office-font
group (10 fonts) reported as an informational N/10 with no install nudge.
Ported across all three wrappers (Python, JS, .NET) to keep them in sync.
Follow-up fixes for the geoip-no-proxy and start-maximized commits:
- geoip: resolve the egress IP before the DB check so a DB-download failure
still yields the WebRTC exit IP — the proxy WebRTC spoof survives a DB hiccup
- geoip: skip the exit-IP echo call on no-proxy + explicit tz/locale (the WebRTC
IP would just be the real connection IP the site already sees — a no-op)
- launch_context: suppress auto --start-maximized when the caller set an explicit
viewport, matching JS across Python and .NET
- docker: poll for X readiness before starting openbox instead of a blind sleep
(avoids a silent window-manager startup race)
- refactor: extract the WebRTC exit-IP append into one helper per wrapper
- remove a dead isPrivateIp in the JS wrapper
- tests: fix stale no-proxy geoip assertions; add launch_context parity + .NET
geoip coverage
Python, JS and .NET wrappers kept in parity.
Default headed and headless launches to a maximized window (fills the
screen) on binaries at or above the same threshold as the headless
no-viewport default. Suppressed when the caller sets --window-size /
--window-position / --start-maximized or an explicit viewport; older
builds are unchanged. Version-gated via a dedicated helper sharing the
no-viewport threshold. Mirrored across Python, JS and .NET with parity tests.
The Docker image runs openbox so headed --start-maximized is honored
(bare Xvfb has no window manager; headless is unaffected).
When geoip=True and no proxy is set, resolve the machine's own public IP
directly (echo services, no proxy) and use it for timezone, locale, and the
WebRTC exit IP — same path as the proxied case. Previously geoip no-oped
without a proxy, leaving UTC + en-US in bare Docker/cloud launches.
Expand COUNTRY_LOCALE_MAP from 50 to 132 countries across all three wrappers
(Python, JS, .NET) so far more egress IPs resolve a locale.
Mirrored in cloakbrowser/, js/src/, and dotnet/. Tests added for the no-proxy
resolution path.
Headed launches already skip Playwright's emulated viewport (no_viewport)
because a fixed CDP viewport on a real window forces outerWidth < innerWidth,
a physically impossible geometry that's a bot tell. Headless historically kept
a fixed DEFAULT_VIEWPORT since there's no window chrome to make coherent
without emulation — but a newer Chromium build (>=148.0.7778.215.4) now
reports coherent dimensions in headless too, so it can drop the emulated
viewport the same way headed does.
Added binary_supports_headless_no_viewport() (mirrored in Python, JS, .NET) to
gate this per resolved binary version: local overrides with no declared
version stay on the old fixed-viewport path (unknown version = safe default),
while an explicit browser_version/CLOAKBROWSER_VERSION always wins so internal
builds can opt in. HEADLESS_NO_VIEWPORT_MIN_VERSION is currently set to a
version that hasn't shipped yet, so this is a no-op until that build is live —
behavior is byte-identical to today for every existing binary.
- Pass the resolved license key via environment (CLOAKBROWSER_LICENSE_KEY)
when launching the Chromium binary so the Pro binary can authenticate.
- Inject key when a custom user_env is provided with default file source:
Playwright replaces (not merges) the child env, which can drop HOME and
prevent the binary from finding ~/.cloakbrowser/license.key.
- Normalize user_env by filtering None/undefined values consistently across
Python, JS, and .NET wrappers.
- Add HomeDirOverride test seam to the .NET wrapper for cache path mocking.
info (plus a doctor alias) now reports the binary that will actually
launch for the resolved license instead of whatever is cached on disk:
it resolves and validates the license, shows the real tier, and on a
keyless or invalid key reports the free binary. Adds a launch test
(chrome --version) with a Linux missing-shared-library probe, a
Windows-font check (Linux only), GeoIP DB presence, and optional-dep
checks. --quick skips the launch test; --json emits machine output.
Python, JS, and .NET, with tests.
One-time, suppressible startup warning when spoofing Windows on a Linux host
with no Windows fonts detected (fc-list probe of the documented base set),
across Python, JS, and .NET. The first-launch banner now re-shows to free
users every 3 days; Pro users still see it once.
The version-check request (get_pro_latest_version) now sends the platform
tag so the server can return a per-OS LATEST pointer, letting us advance
one OS at a time. Mirrored across Python, JS, and .NET clients; older
clients send no header and keep tracking the global LATEST floor.
Pro/Free users can pin a specific Chromium version:
launch(browser_version='148.0.7778.215.2')
CLOAKBROWSER_VERSION=148.0.7778.215.2
- normalize_requested_version() validates version format (4-5 segs, no path traversal)
- Free path: downloads pinned version from public URL
- Pro path: routes pinned version through existing license validation API
- Pinning does NOT overwrite the 'latest' version marker
- JS: browserVersion option, normalizeRequestedVersion(), env support
- .NET: BrowserVersion option, NormalizeRequestedVersion(), env support
- .NET 8 / C# client published to NuGet (PR #385, @evelaa123)
- macOS Pro binary now available (darwin arm64 + Intel), so Pro downloads
the latest build on every platform
- README: Platforms table split into Free/Pro; drop the stale Roadmap and the
macOS-fingerprint troubleshooting note
The macOS Pro build (darwin arm64 + Intel) is now served alongside Linux and
Windows, so a Pro license downloads the latest binary on macOS like every
other platform.
Reverts the v0.4.2 stopgap that, on macOS only, silently fell back to the free
binary when the Pro download returned 404 (there was no macOS Pro build yet). A
valid license now hard-fails on any Pro download error on every platform — no
silent downgrade — restoring the wrapper's stated invariant. Applied across the
Python, JS, and .NET wrappers; removes the now-unused DownloadHttpError type and
its tests.
README: macOS listed as available for Pro.
Main README: add the .NET / C# install block + credit the .NET client.
dotnet/README (NuGet page): fix license-key example (ck_live_ -> cb_),
add free/Pro tier framing + plans link, add a persistent-context example,
drop the repo-only pre-install/CLI commands for package consumers.
- ci.yml: build + test the dotnet client on every push/PR
- publish.yml: publish-nuget job (OIDC trusted publishing via NuGet/login),
wire the workflow_dispatch job selector so single jobs can run,
validate tag == csproj <Version>
- csproj: pack dotnet/README.md as the NuGet package readme
