Browser-use safety playbook: isolate execution, restrict hosts, treat pages as untrusted
cfregly · x · 2026-11-01
- Practical guidance for API-based browser use: isolate execution, restrict allowed hosts, treat page content as untrusted, and confirm consequential actions in the executor.
- Contrast with Claude Code for Chrome: actions run in a visible window and reuse your logged-in session; you manage site permissions and handle logins/CAPTCHAs. Self-hosting means owning executor, isolation, and approval work.
- Choose by session owner and human-in-the-loop needs; Playwright MCP is an alternative depending on tooling and deployment fit.
- Links official docs: Claude Code opens tab groups in Chrome/Edge for testing, debugging, form filling, and data extraction.
