Stealth Chromium Build

Pre-built Chromium with 58 source-level fingerprint patches.

See the full CHANGELOG for details.

What's New (Binary)

• Rendering consistency improvements across Linux and Windows — corrected GPU, display, and graphics parameters to match stock Chrome 146 profiles
• Windows: native GPU/rendering values now pass through directly instead of being spoofed, matching real hardware behavior
• Storage normalization fix for Windows
• HTTP proxy inline credential support at the network layer

What's New (Wrapper v0.3.27–v0.3.30)

• extension_paths — load Chrome extensions in all launch functions
• Humanize actionability — auto-wait for visible, enabled, stable elements before humanized actions
• Per-call human_config — override humanize settings on individual method calls
• Composable JS helpers — buildLaunchOptions() and humanizeBrowser() for custom Playwright integrations
• Puppeteer launchPersistentContext() — persistent profiles in Puppeteer
• GeoIP timeout guard — bounded with 10s timeout so launch() cannot stall
• cloakserve security — WebSocket origin guard, fingerprint seed sanitization
• Nix flake for NixOS users
