Maker
📌
Hey everyone! I'm the maker of Claude Code Open.
I built this because I believe every developer deserves access to a powerful AI coding assistant - without paying $200/month for a subscription. Claude Code Open gives you the full Claude Code experience using just your own API key.
What makes it special:
- Web IDE with Monaco Editor - code in your browser, no terminal needed
- Blueprint multi-agent system - breaks complex tasks into parallel subtasks automatically
- 37+ built-in tools for file ops, code analysis, git, web search, and more
- Self-evolving architecture - the AI can improve its own capabilities
- Runs on Windows/macOS/Linux, MIT licensed
The project started as a reverse-engineering study of Claude Code CLI, but evolved into something much more - a full platform with Web UI, background task scheduling, MCP protocol support, and a multi-agent orchestration system.
