🚀 Quick Start

📥 Download & Run

🧩 Download

curl -L -o Browser4.jar https://github.com/platonai/Browser4/releases/download/v4.8.0/Browser4.jar

🚀 Run

echo $OPENROUTER_API_KEY # make sure LLM api key is set. Also supported: OPENROUTER_API_KEY/OPENAI_API_KEY/DASHSCOPE_API_KEY/VOLCENGINE_API_KEY.
java -D"OPENROUTER_API_KEY=${OPENROUTER_API_KEY}" -jar Browser4.jar

🔍 Tip: Make sure OPENROUTER_API_KEY or other LLM API key is set in your environment, or AI features will not be available.

🔍 Tip: Windows PowerShell syntax: $env:OPENROUTER_API_KEY (environment variable) vs $OPENROUTER_API_KEY (script variable).

CLI & SKILLS

Browser4 CLI is a powerful command-line interface for direct browser control and automation, designed for both human
users and AI agents. It provides a simple syntax to perform complex browser interactions without writing code.

Browser4 CLI is compatible with Playwright and supports a wide range of commands for navigation, interaction, and data extraction.
It can be used in scripts, terminal sessions, or integrated into AI agents through SKILLS.
