Agent Browser
This project is an agentic framework designed to enable autonomous web navigation and browser automation. It functions as a controller that translates natural language instructions into deterministic browser actions, allowing agents to interact with websites, perform data extraction, and manage complex authentication flows. By leveraging accessibility trees and semantic element resolution, the framework mimics human-like navigation, moving beyond brittle DOM selectors to interact reliably with modern web interfaces.
The framework distinguishes itself through its focus on secure, scalable execution and deep observability. It provides a unified abstraction layer for managing browser instances, whether they are running locally, in containerized environments, or via remote cloud infrastructure. To ensure security and consistency, it utilizes microVM-based isolation and policy-driven gating, which allows developers to enforce human-in-the-loop verification for sensitive operations and maintain strict resource constraints during automated sessions.
Beyond core navigation, the project offers a comprehensive suite of tools for managing long-running workflows and debugging agent behavior. It supports persistent session management to maintain authentication states across tasks, alongside advanced observability features like real-time viewport streaming, performance profiling, and network traffic inspection. These capabilities allow for the monitoring of agent activity and the diagnosis of complex interactions within dynamic web applications.
The framework is designed for programmatic integration, providing a flexible interface to connect with external AI assistants and automated systems. It includes extensive support for configuring browser environments, injecting custom scripts, and handling complex page states, making it suitable for both exploratory testing and production-grade automation tasks.
