Agent Browser

A fast Rust-based headless browser automation CLI with Node.js fallback that enables AI agents to navigate, click, type, and snapshot pages via structured commands.

When to use

• Automating web interactions (login, form fill, scraping)
• Extracting structured data from pages
• Testing web UIs or workflows
• Filling forms programmatically

Prerequisites

• Node.js ≥ 18
• npm install -g agent-browser (run once to install CLI)

How it works

1. agent-browser open <url> → launch browser & navigate
2. agent-browser snapshot -i → get interactive elements with stable refs (e.g., @e1)
3. Use refs to interact: click @e1, fill @e2 "text", wait @e3
4. agent-browser close → clean up

Key capabilities

• Snapshot with accessibility tree or interactive-only mode
• Precise element interaction (click/fill/hover/drag/upload)
• Wait conditions (element visible, URL change, network idle)
• Screenshot, PDF export, video recording
• Cookie/storage/network control
• Tab/window/frame management
• JSON output for programmatic parsing

Example

agent-browser open https://example.com/login
agent-browser snapshot -i
agent-browser fill @e1 "user@example.com"
agent-browser fill @e2 "password123"
agent-browser click @e3
agent-browser wait --url "/dashboard"
