browser-act

Browser automation CLI for AI agents. Runs a full browser engine: navigation &

interaction, data extraction & network capture, screenshots, form automation,

multi-browser parallel operation, user-configured proxy support, and

human-agent collaboration.

Features

• Lightweight extraction — fast JS-rendered content fetch without opening a browser session, advanced WebFetch/curl replacement
• Session management — multi-browser isolation, multi-account parallel operation
• Verification assistance — when automation encounters interactive challenges, assists completion with user authorization
• Complex interaction — network capture (XHR/fetch/HAR), screenshots, form filling, file upload
• Human-agent collaboration — headed mode + remote assist for manual steps
• Safety controls — Confirmation Gate protocol requires explicit user approval before browser creation, deletion, and sensitive operations
• Universal compatibility — works with Cursor, Claude Code, Codex, Windsurf, etc.

Install: uv tool install browser-act-cli --python 3.12

Start here

Before running any browser-act command, load the usage guide from the CLI:

browser-act get-skills core --skill-version 2.0.0   # start here — workflows, common patterns, troubleshooting

Do NOT skip this step regardless of how simple the command seems.

Do NOT truncate the output — it contains operational directives and

environment state that are critical for correct operation. Truncating will

cause you to miss browser selection rules and safety constraints.

get-skills core provides environment status, available browsers, operational

directives, and the complete interaction workflow — none of which are available

through --help.
