Anti Detect Browser
Drive Chromium from standard Playwright APIs with a real-device fingerprint applied inside the browser kernel, one persistent isolated profile per identity, and a per-profile proxy whose exit IP sets timezone and WebRTC - JavaScript/TypeScript (npm 'anti-detect-browser') or Python (PyPI 'antibrow'). Use when sessions must stay logged in across runs and stay separate from each other, when a scraper or agent keeps getting blocked because a headless build's fingerprint is incoherent, when checking ads or pricing from another region, when operating several of your own accounts from one machine, or when testing how your own bot detection scores a real device. Also for 'antibrow', 'anti-detect browser', 'fingerprint browser', 'multi-account browser', 'account association', '防关联', '多账号', 'CreepJS', 'whoer', 'pixelscan', 'residential proxy', 'browser-use', 'crawl4ai', 'Scrapling', 'Playwright stealth'. MCP control is browser-mcp-agent; isolation checklist is multi-account-isolation.

From the source SKILL.md
Launch Chromium instances with real-device fingerprints via standard Playwright APIs. Every profile carries one coherent, real-device identity that is frozen at creation and replayed byte-for-byte on every later launch.

When should I use the Anti Detect Browser skill?
Use Anti Detect Browser when your Claude Code task falls under the Engineering category — specifically in the testing area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Anti Detect Browser" or describe the task and let Claude pick). Browse related skills at
/category/engineering/.
What is a Claude Code skill and how does the Anti Detect Browser skill fit in?
