agent-browser CLI

A headless browser automation CLI designed for AI agents, with fast Rust-based execution and element refs optimized for LLM reasoning.

Overview

agent-browser provides programmatic browser control through a CLI that's purpose-built for AI agent workflows. It uses deterministic element references (@e1, @e2, etc.) from accessibility trees, making it ideal for LLM-based automation where consistent element targeting is critical.

Key Features:

• Fast Rust-based CLI with Node.js fallback
• Element refs (@e1, @e2) for stable LLM reasoning
• Session isolation for parallel browser instances
• JSON output for programmatic parsing
• Accessibility tree snapshots for element discovery
• CDP connection support for existing browser instances
