Fingerprint kernel credit: the fingerprint isolation is provided by CloakBrowser © CloakHQ — a stealth Chromium with source-level fingerprint patches. Abencat Browser is an open-source controller / launcher around that kernel. The kernel is not redistributed in this repo; download it with the script below. All credit for the browser engine goes to CloakHQ. See NOTICE.
- Fingerprint isolation — Canvas / WebGL / Audio / Fonts / WebRTC, per-profile seed; passes bot detection (via CloakBrowser kernel).
- Automation API — every launch auto-allocates a debug port and returns a CDP WebSocket; connect Puppeteer / Playwright / Selenium instantly.
- MCP server — AI agents (Claude, Cursor, …) create / start / control environments directly. See AGENT_AUTOMATION.md.
- Proxy pool + GeoIP — bulk import, health checks, auto-sync language / timezone / exit IP from the proxy.
- Local encryption — proxy passwords & cookies encrypted at rest (AES-256-GCM), optional Argon2id master password.
- Cross-platform & headless — Windows desktop + Linux server; switch headed/headless per launch.
- i18n — UI in 8 languages (zh/en full + ja/ko/ru/es/fr/de).
