Typing (Python, JS Playwright/Puppeteer, .NET)
- Absolute-time Typist: log-normal hold (~100 ms), key-pair dependent
inter-key gaps (space, same/other hand, repeated letter), rollover via
queued releases, Shift often released before the letter, no key pressed
twice, all held keys released on error. A lower-case press of a key is
released before Shift + the same key goes down ("xX", "1!"), so no
keydown with repeat=true.
- Defaults moved to Aalto 136M Keystrokes: typing_delay 150, key_hold
(60, 175), mistype_chance 0.04; careful preset updated.
Mouse
- Fitts-law stroke duration (mouse_time_base / per_bit / spread),
log-normal run-to-run spread, frame-rate events, time-warped
minimum-jerk profile with an early velocity peak, gentle curvature and
wobble, no zero-movement events, notch-free overshoot correction.
Scroll
- Whole wheel notches of the persona's platform (Win 100, mac 40,
Linux 120; scroll_notch_px override) in short flicks, so deltaY agrees
with CDP's one-notch wheelDeltaY; overshoot measured in notches.
- scroller() in the isolated-world helpers walks the containing-block
chain: fixed boxes skip ancestors that do not establish a containing
block for them, absolute boxes skip static ancestors. A fixed modal in
a scrolling panel is clicked instead of timing out with "element is
outside of the viewport". All three helper copies stay byte-identical.
Removed
- Settings with no effect after the change: mouse_steps_divisor,
mouse_burst_size, mouse_burst_pause, scroll_delta_base,
scroll_delta_variance (and the .NET properties). Python drops them from
human_config with a FutureWarning that points at the caller; JS and the .NET override
dictionary ignore them. The standalone .NET HumanScroll wheels in whole
notches too. READMEs updated to the new defaults.
- .NET: a "\r\n" text element is inserted as text again (it threw
"Unknown key" from KeyDownAsync).
Tests: timing/rollover/notch/zero-move tests; five #593 cases in Python,
JS and .NET; puppeteer/stealth tests updated to the new semantics.

GeoLite2 classifies some datacenter proxy exits as SC; with no entry in
COUNTRY_LOCALE_MAP the lookup returned no locale and geoip=True failed.
Add SC -> en-SC to the Python, JS and .NET maps.
Fixes#591
Python async launchers ran the binary/license check and the GeoIP and
WebRTC exit-IP lookups on the caller's event loop, freezing every other
coroutine for up to 20s per launch. Run them via asyncio.to_thread.
.NET: license validation and Pro version lookups inside async download
methods now run via Task.Run instead of holding the caller's thread.
A persistent context arrives with a page already open. The license guard
stores its wrappers on that page object, and an object attribute shadows the
class methods humanize patches, so guarding first pinned Playwright's own
methods and silently disabled humanize on that page. Python (sync and async)
and JS now humanize first, then guard. The .NET wrapper already composes in
this order; new tests lock it in.
- tests: Python call-order tests, JS real-browser guard-on-humanized-page
test, .NET LicenseGuardCompositionTests
- remove internal support references from code comments and test docstrings
page.input_value / text_content / inner_text / inner_html / get_attribute and
dispatch_event now resolve and read through the humanize isolated world, like
every other humanized call, for page, frame, locator and element handle (sync
and async). The raw Playwright path stays reachable through page._original /
Original / Humanize.Unwrap.
- shared world helper library gains the inputValue / textContent / innerText /
innerHTML / getAttribute / dispatchEvent ops (byte-identical across the
Python, JS and .NET ports)
- engine read() / dispatch() (Python), read / dispatch (JS),
ReadAsync / DispatchAsync (.NET): deadline, resolve-until-match, one world
call, {value} / {error} mapping, Playwright error labels
- wrappers expose the six APIs on Page, Frame, Locator and ElementHandle;
generator delegation guards updated so they stay hand-written
- an ElementHandle read / dispatch on a hidden element, or one sharing its box
with another element, and a dispatch whose event_init holds a JSHandle, run
Playwright's own call, as before
- tests: Python unit and real-browser tests, JS real-browser engine tests,
.NET HumanReadsTests (values, late selector, null / world error / timeout
mapping, dispatch event shape, frame reads, hidden / same-box handles,
JSHandle event_init)
The dropdown search reads one UTF-16 unit per key and drops a surrogate, so
a typed emoji never moves it. The type-ahead plan no longer types one: Linux
and Windows reach such options with arrows. A macOS dropdown ignores arrows
too, so there the option raises a clear error before the popup opens.
The long-dropdown test now allows one input/change per letter on macOS.
_check_playwright() looked for `_frame` in
ElementHandle.__init__.__code__.co_names. In a compiled build (e.g.
Nuitka) that code object is a placeholder, so a supported Playwright was
reported as "missing internals: ElementHandle._frame" and every
humanized launch failed.
Only read bytecode from plain Python functions; anything else is left to
the version check.
A dropdown is now picked the way a person picks from a long list: open it,
type the first letters of the option, add a few arrow keys when that is
shorter, press Enter.
- The plan comes from a new __cloakH helper (typeAheadPlan), shared byte for
byte by Python, JS and .NET. It picks the shortest prefix that matches
exactly one enabled option, so the result does not depend on which row the
open popup highlights. That row cannot be read from the page, and on headed
Linux it can be the one under the OS pointer (#580). Prefixes of the
option's own name win; a neighbour's prefix plus up to 3 arrows is used only
when it is shorter. Runs of one letter ("aa") are avoided because Blink
cycles on them.
- Blink joins letters typed within 1s into one search, so a second
select_option on the same page waits for the previous search to lapse.
- The deadline is checked before every key; on timeout the popup is closed
with Escape and a TimeoutError is raised (#581: timeout= was ignored).
- macOS hosts (no arrow keys in the native popup) type the shortest unique
prefix instead of the whole label.
- Labels with no unique prefix (duplicates) fall back to Home + arrows, or the
full label on macOS.
Measured on headed Linux (Xvfb), humanize defaults: #581's 205-option list
1.5-2s per pick (was 20-30s); 166-country list and #580's page with the OS
pointer parked over the popup, 144/144 correct.
SOCKS5 and credentialed HTTP proxies are set on the browser, so
context.request / page.request / route.fetch() send from the real IP.
Warn once on first use (Python + JS) and document in-page fetch.
Humanized actions in the Playwright wrappers (Python, JS, .NET) now run through a
single shared engine built on Playwright's own selector engine: full locator support
(roles, chains, filters, frame locators, strict mode), Playwright options honoured,
value inputs operated with real input, persona-aware keys, and errors instead of
silent fallbacks. Puppeteer: frame-scoped actions, button/count, Shift on typos.
Follow-ups: macOS dropdowns via type-ahead, nested same-box element handles,
stale handles fail fast, CI fails on a missing test binary.
Tests marked slow or real_browser skip the per-test temp cache and use
~/.cloakbrowser like a real install: the developer's key and latest
binary at a stable path. The temp cache re-downloaded the keyless
binary for every test under a new path, which path-keyed firewalls
re-prompt for. Unit tests stay isolated.
launch_persistent_context() now stores its seed in <user_data_dir>/.cloakbrowser-seed
on first launch and reuses it, so a profile keeps one identity across sessions.
Same file format in Python, JS and .NET. An explicit --fingerprint in args wins
and leaves the file alone; stealth_args=False skips it; non-persistent launches
stay random. Concurrent first launches publish without overwriting (link), so
they agree on one seed. Filesystems without hard links (FAT/exFAT, some network
mounts) fall back to an exclusive create, and an empty file is re-read briefly
as in-progress. A corrupt file is logged and regenerated.
* fix(download): make concurrent first-run downloads safe
_extract_archive deleted the install dir and then extracted into it in
place. When several processes or threads start on an empty cache, a
second caller can delete the first caller's install mid-extraction, or
pass the "binary exists and is executable" check on a binary that is
still being written. On Linux that surfaces as ETXTBSY on spawn; on
macOS as dlopen failures and "Directory not empty", and the cache can
be left permanently incomplete.
Extract into a uniquely named sibling staging dir and rename it into
place. If the destination already holds a complete install, another
caller won and the staged copy is discarded; an incomplete leftover is
still replaced as before.
* fix(js): make concurrent first-run downloads safe
Same race as the Python wrapper: extractArchive deleted the install dir
and extracted into it in place, so concurrent ensureBinary() calls on an
empty cache could delete each other's install or return a binary that
was still being written (spawn ETXTBSY on Linux).
Extract into a uniquely named sibling staging dir and rename it into
place, keeping an existing complete install if another caller won.
Also name the temporary archive with randomUUID() instead of
Date.now(), which collided for calls made in the same millisecond.
* fix(dotnet): make concurrent first-run downloads safe
Same race as the Python and JS wrappers: ExtractArchive deleted the
install dir and extracted into it in place, so concurrent
EnsureBinaryAsync() calls on an empty cache failed with "already
exists" / DirectoryNotFoundException or saw a half-written install.
Extract into a uniquely named sibling staging dir and move it into
place, keeping an existing complete install if another caller won.
* fix(download): replace a partial install safely under concurrent callers
When an incomplete install dir was left over from an interrupted run,
every concurrent caller saw it as incomplete and deleted it in place.
The first to finish renamed its staging dir into place; the others'
unguarded second rename then failed (ENOTEMPTY, FileNotFoundError,
DirectoryNotFoundException), and a late delete could remove files from
an install another caller had just moved in. With 8 concurrent callers,
7 raised in each round.
Rename the leftover aside to a unique <install>.stale-<id> dir and
delete it from there, then retry the staging rename a bounded number
of times, keeping a complete install if another caller got there
first. Applies to the Python, JS and .NET clients, each with a
regression test that starts several concurrent callers on a partial
install. The JS test uses separate processes, since callers in one
process cannot interleave inside the synchronous rename block.
* fix(download): retry directory renames Windows transiently denies
Antivirus and indexers on Windows briefly hold freshly extracted files
open, which fails the directory rename with access denied. Retry that
rename for about 2.5 seconds while the destination does not exist, in
all three clients. Cleanup of the staging and stale dirs is now best
effort so a failed delete never masks the error being raised.

A letter typo on a digit is rejected by <input type=number>, so the
correcting Backspace deleted the previous real digit (1999 -> 999).
Digit neighbors are now digit-only in the Python, JS (Playwright +
Puppeteer) and .NET wrappers.
Layout can report a top edge of -1/64 px on an unscrolled page, which skipped
the pinned-at-top check and sent a pointless upward scroll burst before the
click. Allow 1px slack in Python, JS and .NET, with regression tests.
Also credit @Shub3am in README contributors (#554).
* fix(humanize): scroll the x axis in scroll-into-view (#521)
humanScrollIntoView only measured and scrolled the y axis. A target past
the right edge of a horizontally overflowing page counted as in view, so
no wheel events were sent, the click point landed offscreen and the
pointer check failed with "element is covered by <none>" after the full
timeout.
After the vertical pass, a horizontal pass now checks that the box fits
inside the viewport width and, if not, centres it with the same
humanized wheel burst on the x axis. It skips the scroll when the page
is already pinned at the needed horizontal boundary, mirroring the y
pinned check. Applied to Python (sync and async), JS Playwright,
Puppeteer and .NET.
.NET: IRawScrollPage.GetScrollStateAsync now also returns X and MaxX.
Fixes#521
* fix(humanize): handle RTL scrollX in the horizontal pinned check (#521)
In right-to-left documents Chrome's window.scrollX runs from 0 down to
-(scrollWidth - clientWidth). The x pass treated "scrollX <= 0" as pinned
at the left edge, so on an RTL page at its start a target in the left
overflow was never scrolled into view and the click failed with "covered
by <none>".
The scroll-state script now also reads the viewport direction (taken from
<body> when present, as Chrome does) and returns an RTL-aware minX and
maxX. Python, JS Playwright and .NET compare against those. The .NET
adapter shifts X and MaxX by minX so IRawScrollPage keeps its tuple shape
and X still runs 0..MaxX.
Puppeteer has no pinned check on the x axis and is unchanged.
* fix(humanize): skip the x pass for sub-pixel distances
A box wider than the viewport never passes the containment check, so
every action on it ran the x pass even when it was already centred: a
mouse move to the scroll area and a 0 or 1px wheel. Skip the pass when
the distance to centre is under 1px. Applied to Python (sync and async),
JS Playwright, Puppeteer and .NET.
* test(humanize): reword the set_content note on the #521 browser tests
The comment stated as fact that set_content never settles in
CloakBrowser. What I observed is narrower: it timed out in local runs of
these tests, so say that instead.
The download is signature/checksum-verified before extraction, so the
per-member path/symlink sanitization was redundant. Extract archives as-is
across all three wrappers (Python, JS, .NET), tar and zip.
- Python: filter="fully_trusted" (pins legacy behavior; 3.14 defaults to
"data"), plain zip extractall
- JS: drop the tar filter callback; inline the one-line extractTar
- .NET: TarFile/ZipFile.ExtractToDirectory; remove orphan ResolveSafeEntryPath
- Drop the obsolete traversal/symlink tests
Add a Mac fonts count to `cloakbrowser info` next to the existing Windows
font check, in the Python, JS, and .NET wrappers. Counts the macOS core
font set via fc-list on Linux and prints Mac fonts: n/20 with a conditional
nudge when incomplete. Tests added in all three wrappers.
The banner wrote '->' and em dashes straight to stderr. On a cp1252/strict
console (UK/EU-locale Windows) that raised UnicodeEncodeError and aborted the
binary-download path, blocking license apply and profile launch in the Manager.
Swap the banner glyphs to ASCII and route the writes through a swallow-all
helper so a cosmetic banner can never abort a launch. Same treatment in the JS
and .NET wrappers plus the Windows-font warning. Regression tests added across
all three (ASCII-only + cp1252-no-crash).
Increase the default GeoIP resolution timeout from 5 to 20 seconds across the Python, JavaScript, and .NET wrappers.
Fail the launch when requested GeoIP resolution times out, cannot load its database, cannot complete a lookup, or leaves timezone or locale unresolved. Explicit timezone and locale overrides remain valid without an egress-IP result.
Add parity coverage for the new timeout and failure behavior.
A supplied license key the server rejects, or one that cannot be validated
(server unreachable, no cache), now raises instead of silently downloading the
free binary. No-key (keyless) and valid-key (Pro) paths unchanged. Python, JS,
and .NET, with mirror tests in each.
Removing the Playwright fallback closed a main-world read leak but left every
get_by_* locator raising UnsupportedHumanizeSelectorError. Reimplement the four
cheap engines in the isolated-world resolver so those locators work again.
Selector engines (shared resolver, byte-identical in all three wrappers):
- internal:testid and internal:attr (placeholder/alt/title). The i flag is a
case-insensitive substring on the raw attribute value; test ids stay strict.
- internal:text. Exact compares the full normalized subtree text, unlike the
public text= engine which compares immediate fragments.
- internal:label, resolving aria-labelledby, then aria-label, then .labels.
- internal:role and >> chaining stay unsupported; the error now names what is
supported and the workaround.
Text parity fixes in __elementText, checked against playwright-core:
- drop a <br> to newline branch Playwright does not have
- concatenate shadow-root text into the host, which Playwright does
- give the public text= engine Playwright's self/selfAndChildren rule, since
contains() cannot see into a shadow root and kept the host as a match
Target identity: payloads carry a per-world generation (protocol v2). The world
is rebuilt on navigation and its id counter restarts, so an id alone could name
a different element. Generation is bounded to Int32, which the .NET wrapper
requires.
force=True now skips the pointer check entirely, matching Playwright, instead of
suppressing only the coverage rejection.
Also: drop dead _BOX_OP, _ACTIONABLE_OP and readSnapshot, and add a test
asserting the three hand-copied resolver literals stay identical and free of
characters that would terminate their host string literals.
Verified against Playwright's own locator resolution in a real browser:
20/20 engine parity, 7/7 text parity.
Derive actionable geometry from rendered text and visible descendants when an element has no box of its own. Preserve existing geometry behavior for normal elements and exclude hidden descendant content. Add Python, JavaScript, and .NET unit and browser regressions covering text, nested content, visibility, and humanized clicks.
Collect light-DOM matches before recursively merging open Shadow Root
matches, preserving Playwright order for broad selectors using first or nth.
Add resolver and real-browser coverage for mixed and nested Shadow Roots.
Resolve#512 by ignoring non-rendered document content during text
matching and selecting the same visible target as Playwright.
Improve text, structural, selector-list, and open shadow-root handling.
Align element state checks and forced-click behavior, and prevent pointer
dispatch when the original target is detached or replaced during mouse
movement.
Add sync, async, and real-browser regression coverage.
`cloakbrowser info` printed a bare seat count with no denominator, so a
customer could not tell whether they were at capacity (#513). It also
collapsed six distinct outcomes into one "unavailable": unreachable,
timeout, invalid key, inactive licence, rate limited, and the server
reporting the count as unknown while degraded.
Adds SessionSeats (active, limit, state, reason) and getSessionSeats to
all three wrappers; get_active_session_count keeps its signature and
delegates. The limit is read from the server, never derived from the plan
name, and falls back to the old bare count when absent.
Python, JS and .NET renderers verified byte-identical.
Humanized actions could fail with an element-not-attached error after a
navigation driven by a click or form submit, since the checks only refreshed
on goto. Now refresh on any main-frame navigation. Python, JS
Playwright/Puppeteer, and .NET. Regression from 0.5.6.
Forward caller-provided press delays through humanized page, frame, locator, element handle, and keyboard paths across Python, JavaScript, and .NET.
Use each automation library's native press operation for shortcut chords while retaining the existing humanized pre-press timing and focus behavior.
Python + JS wrappers. Add a stealth_dom / stealthDom module: reimplements the
common Playwright selector grammar (css, :has-text, text=, xpath=, trailing
>> nth=N) for direct DOM resolution in the isolated execution context, with a
fallback to the regular Playwright read for grammar it can't resolve. World
reads are wrapped so a world/CDP failure falls back rather than propagating out
of the humanized action.
ensure_actionable, ensure_stable, scroll geometry (_get_element_box + the
no_viewport window-size read), and check_pointer_events now read through it,
sync and async. Selector-based main-page actions (click/dblclick/hover/type/
fill/focus/press) are covered; ElementHandle and sub-frame paths unchanged.
JS routes Locator actions through frame methods, so main-frame locator clicks
now delegate to the humanized page methods (which use the shared helpers)
instead of the frame-scoped Playwright reads; sub-frames unchanged.
Tests: builders + parse, the rewired helpers' branching via a mock isolated
world, a Node-driven check of the shipped resolver JS selector semantics, and a
guard that main-frame locator clicks delegate to the humanized page path.
- humanize frames created after page load across Python and JavaScript\n- keep sync, async, Playwright, and Puppeteer paths idempotent\n- wrap .NET frame lifecycle event payloads without raw frame leaks\n- add cross-wrapper unit and browser regression coverage
Wire the existing launch()-time geoip resolver into the info/doctor command
across Python, JS, and .NET. With --proxy, info resolves the exit IP and the
timezone/locale a launch would apply (caching the GeoIP DB if absent) and prints
them in text and --json. Plain info is unchanged (no network) and now hints at
the flag. Adds diagnostics tests in all three suites.
A concurrent-session denial resolves after the CDP handshake, so the browser
exits with a live connection already established. The launch-failure path never
sees it and the user gets a bare TargetClosedError on their first call (#477).
The binary records the license exit code (76-79) to a per-launch file whose path
the wrapper passes via CLOAKBROWSER_LICENSE_STATUS_FILE. The wrapper reads it
when a guarded call throws and re-raises the correct CloakBrowserLicenseError.
Discrimination is on the file, not the error type, so a genuine crash is never
mislabelled. Fail-safe (no key or unwritable dir -> feature off) and
backward-compatible (old binaries never write the file).
Guarded surfaces: new_page/new_context, a persistent context's already-open
pages (goto + the wait family), and Puppeteer user-created contexts. Orphaned
denial files are swept at mint time; an observed code is cached in-process so a
concurrent second call can't miss it; the .NET reader parses as tolerantly as
Python/JS.
Implemented across Python, JavaScript (Playwright + Puppeteer), and .NET, with
unit tests. Reproduced end-to-end with a real over-cap denial.
cmd.exe defaults to cp850/cp1252, which carry no check mark or arrow.
Printing one raised UnicodeEncodeError and aborted the report at the
Launch line, so everything after it was lost — including on the success
path, once the launch probe stopped failing.
Marks now degrade to plain text per glyph when the console cannot
encode them. UTF-8 consoles (Linux, macOS, Windows Terminal) keep the
original output byte for byte.
.NET substitutes rather than throwing here (verified on the reference
box), so only the Python wrapper needed the change.
Chromium only handles --version on POSIX, so on Windows the switch is
ignored and a browser starts instead of printing. The 10s probe then
timed out and a healthy install was reported as broken, flashing a
window on screen each run.
Probe with --no-startup-window there: it exits immediately, opens no
window, and a broken binary still exits non-zero. No version is
reported on Windows, as nothing is printed. Linux and macOS unchanged.
Test uses a stub that hangs unless the flag is passed, mirroring the
real binary rather than a print-and-exit stub.
A license.key or cached Pro marker in the developer's cache dir resolved the
box as Pro, flipping version-gated defaults (headless no_viewport, inline proxy
auth) and failing 9 Python + 4 JS tests locally. Both suites now run against a
temp cache dir.
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
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
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.
