opera-browser-cli - Opera Neon's open-source command-line tool

What is opera-browser-cli

opera-browser-cli is Opera Neon an open-source command-line tool launched by, built on a wrapper around opera-devtools, supporting local AI agents (such as Claude Code) to directly control the browser through the terminal. opera-browser-cli requires no cloud relay or complex authentication, and installation can be completed with two commands, allowing AI to evolve from a "question-and-answer tool" into a digital assistant capable of running web tests, scraping data, and generating web applications, marking the browser's formal entry into the AI Agent era.

Main features of opera-browser-cli

• Terminal-driven browser: Open web pages, capture page snapshots, and execute automated operations via the command line.
• AI agent commands: Supports Opera Neon-exclusive AI features such as Do, Make, and Research, and can directly generate web applications.
• Web testing and data scraping: Local AI agents can automatically run tests, scrape web data, and handle online forms.
• Automated integration: Automatically configures SKILLs for Claude Code, ready to use out of the box.
• Comprehensive browser control: Provides 38 commands, covering scenarios such as navigation, screenshots, element operations, and AI generation.

How to use opera-browser-cli

• Environment preparation: Ensure the system has Node.js ≥ 20 and npm installed; Windows users need to confirm PowerShell version 7.0 or above.
• Installation and configuration: Run in the terminal npm install -g opera-browser-cli && opera-browser-cli setup to complete global installation and initialization.
• Launch the browser: Run opera-browser-cli open https://operaneon.com to drive Opera Neon to open the target web page.
• Execute operations：
  • Use opera-browser-cli snapshot to capture a snapshot of the current page for AI to analyze the page content.
  • Via opera-browser-cli make "create a web app..." to call AI to directly generate a web application.

Core advantages of opera-browser-cli

• Local direct connection, zero cloud relay: Directly binds to local port 9224 to run, requiring no cloud authentication or complex MCP configuration, greatly reducing latency and token consumption.
• No OAuth authentication required: Unlike other solutions, you can use it directly after logging in to Opera Neon, eliminating the cumbersome authorization process.
• Tool-agnostic, platform-unrestricted: Any AI agent or tool that supports CLI can call it, and it is not tied to specific platforms such as Claude Code.
• More comprehensive features: Fully covers the chrome-devtools-mcp interface, while also exclusively supporting Opera Neon's three major AI agent commands: Do, Make, and Research.
• Open-source, lightweight, one-click start: Fully open-source on GitHub; installation is completed with two commands in a Node.js environment, and the script automatically configures SKILLs.
