OpenCLI: Turn Any Website Into a Command-Line Tool for Claude Code

The Claude Code ecosystem is shifting toward CLI tools, and OpenCLI is the latest example. Released just days before this video, it had already hit 2,000 GitHub stars. The tool turns any website, Electron app, or local tool into a CLI that Claude Code can operate through.

What OpenCLI Does

OpenCLI works like browser automation packaged as a command-line interface. Point it at a website like Reddit, and you can control that site from Claude Code even without access to the Reddit API. The tool handles the browser session under the hood, letting your agent interact with the site through simple CLI commands.

This is different from the earlier CLI Anything tool in scope. OpenCLI ships with 53 pre-built adapters for services including Reddit, Hacker News, Twitter/X, Bilibili, YouTube, Codex, and Cursor. Each adapter defines the available commands for that platform.

How It Integrates With Claude Code

You configure an instruction in your global AGENT.md file. From there, the AI executes opencli list via Bash to discover available tools and adapters. The agent learns what commands are available and uses them directly.

The practical use case is accessing services where a traditional API does not exist or where API access is restricted. Instead of writing browser automation scripts manually, OpenCLI provides a clean command-line abstraction that Claude Code can work with natively.
