ClaudeCode-Next

An unofficial CLI coding agent that runs on the Claude.ai web interface.

This tool lets you use Claude as a coding assistant from your terminal – reading files, running commands, refactoring code – without needing an API key or paying per-token. It extracts your Claude.ai session from your browser once, then works entirely from the CLI and it's completely free.

What it does

• Read/write files in your project
• Run shell commands (git, npm, tests, builds)
• Search code and refactor across multiple files
• Interactive REPL with agent mode
• Workspace-restricted operations with confirmation

How it's different

Claude Code (official) : Uses API keys, per-token billing, guaranteed reliability
This tool : Uses your browser session, free with Claude.ai subscription, may break if the web UI changes

Who it's for

• Developers without Claude API access
• Hobbyists who want to experiment with CLI coding agents
• Anyone who prefers the terminal over the chat interface
