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

opera-browser-cli is an open-source command-line tool from Opera Neon, built on top of opera-devtools, that supports local AI agents (such as Claude Code) to directly control the browser via the terminal.

What is opera-browser-cli?

opera-browser-cli is an open-source command-line tool from Opera Neon, built on top of opera-devtools. It supports local AI agents (such as Claude Code) to directly control the browser via the terminal. Opera-browser-cli requires no cloud intermediaries or complex authentication; installation can be completed with just two lines of commands. It allows AI to evolve from a "question-answering tool" into a digital assistant capable of running web page tests, scraping data, and generating web applications, marking the browser's official entry into the AI Agent era.

Main functions of opera-browser-cli

  • Terminal-driven browser: Open web pages, capture page snapshots, and perform automated operations via command line.
  • AI Agent CommandsSupports Opera Neon's proprietary AI features such as Do, Make, and Research, and can directly generate web applications.
  • Web testing and data scrapingThe local AI agent can automatically run tests, scrape web page data, and process online forms.
  • Automation IntegrationAutomatically configures skills for Claude Code, ready to use out of the box.
  • Full browser controlIt provides 38 commands, covering scenarios such as navigation, screenshotting, element manipulation, and AI generation.

How to use opera-browser-cli

  • Environmental preparationEnsure your system has Node.js version ≥ 20 and npm installed. Windows users need to confirm PowerShell version 7.0 or higher.
  • Installation and Configuration: Execute in the terminal npm install -g opera-browser-cli && opera-browser-cli setup Complete global installation and initialization.
  • Launch browser:implement opera-browser-cli open https://operaneon.com This will drive Opera Neon to open the target webpage.
  • Execute operation:
    • use opera-browser-cli snapshot Capture a snapshot of the current page for AI to analyze the page content.
    • pass opera-browser-cli make "create a web app..." Use AI to directly generate web applications.

The core advantages of opera-browser-cli

  • Local direct connection, zero cloud relayIt runs directly on the local port 9224, without requiring cloud authentication or complex MCP configuration, significantly reducing latency and token consumption.
  • No OAuth authentication requiredUnlike other solutions, it can be used directly by logging into Opera Neon, saving you from the cumbersome authorization process.
  • Tool-independent, platform-independentIt can be invoked by any AI agent or tool that supports CLI, and is not bound to specific platforms such as Claude Code.
  • More comprehensive functionsIt fully covers the chrome-devtools-mcp interface and exclusively supports Opera Neon's three major AI proxy commands: Do, Make, and Research.
  • Open source and lightweight, easy to use with one clickCompletely open source on GitHub, installation can be completed in two lines of commands in a Node.js environment, and the script automatically configures SKILLs.

Application scenarios of opera-browser-cli

  • AI Automated TestingAllow local AI agents to automatically run webpage function tests without requiring manual page-by-page operation.
  • Intelligent data captureAI directly controls the browser to capture dynamic web page data and generate structured reports.
  • Rapid prototyping:pass make The command allows AI to directly generate working web applications based on natural language descriptions.
  • Online form processingAutomatically fills out and submits complex forms, completing repetitive tasks such as booking tickets and registering.
  • Browser automation workflowCombined with tools such as Claude Code, it enables the construction of end-to-end automated development processes.
