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.
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.
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.
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.
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.
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.
The `proxy` parameter now accepts a Playwright proxy dict
({server, bypass, username, password}) in addition to URL strings.
Dict proxies are passed directly to Playwright, enabling bypass
lists and other advanced proxy options.
- Add ProxySettings TypedDict for Python type safety
- Extract server URL from dict proxies for geoip resolution
- Handle dict proxy args/auth in Puppeteer wrapper
- Strip inline credentials from dict proxy server URL in Puppeteer
- Fix JS launchContext() double-setting timezone (binary flag + context)
- Remove unnecessary non-null assertions in TS geoip helpers
- Use nullish coalescing for password fallbacks
- Add unit tests for geoip with dict proxy input
Parse user:pass from proxy URLs into separate Playwright username/password
fields. Puppeteer wrapper strips credentials from --proxy-server and
auto-calls page.authenticate(). Bump Python 0.1.6, JS 0.1.3.
Adds js/ package mirroring the Python wrapper architecture:
- Dual API: import from 'cloakbrowser' (Playwright) or 'cloakbrowser/puppeteer'
- TypeScript with full type definitions
- Same binary download/cache logic, same stealth args, same env vars
- Optional peer deps: users install only the runtime they need
- Full 6-site stealth test suite (sannysoft, incolumitas, BrowserScan, deviceandbrowserinfo, FingerprintJS, reCAPTCHA v3)
- Published to npm as cloakbrowser@0.1.2
