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.
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.
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)
- 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
