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.
- Add linux-arm64 to PLATFORM_CHROMIUM_VERSIONS (Python + JS)
- Multi-arch Docker build (linux/amd64 + linux/arm64) via QEMU in CI
- Add ko-fi donate link to welcome banner (Python + JS)
- Version bump to 0.3.16
Binary:
- Upgrade Linux x64 build to Chromium 145.0.7632.159.7 (33 C++ patches)
- StorageBuckets API quota normalization — closes last storage-based incognito detection vector
Wrapper:
- Fix non-ASCII character support in humanized typing (Cyrillic, CJK, emoji)
- Document storage quota tradeoff for persistent contexts
- Add Ko-fi funding link
