The agent-browser is a command-line interface (CLI) tool designed for headless browser automation, aimed at AI agents. Built primarily in Rust, it offers a Node.js fallback for broader compatibility. Installation is straightforward: you can install it globally via npm or Homebrew, and it provides commands to download Chromium and set up the environment. For Linux users, there’s an option to install system dependencies alongside the browser. The tool allows various interactions with web pages, such as opening URLs, clicking elements, filling out forms, and taking screenshots. You can interact with elements using CSS selectors or ARIA roles, making it flexible for different web applications. It supports actions like scrolling, dragging and dropping, and uploading files. For automation tasks, commands can wait for elements or specific conditions, ensuring that scripts run smoothly. Agent-browser also enables users to manage sessions, allowing multiple isolated browser instances with their own cookies and storage. By using the `--profile` option, users can persist the browser state across sessions, which is useful for maintaining login states or other user-specific data. The CLI includes features for tracing, console logging, and network request interception, providing a comprehensive toolkit for web automation and testing.
