🎯 Why Antomix?

Hey there! I'm Unclecode, author of Crawl4AI ( ⭐).

After trying alternatives like Gemini CLI and Qwen Code, I realized something: The magic of Claude Code isn't just the model - it's the assistant itself. The way it's engineered as an agentic coding assistant is what makes it so efficient. I wanted this incredible experience with ALL models, not just Claude. So I built Antomix!

The result: A universal proxy that converts any app connecting to Anthropic to work with:
- 🔥 Groq (lightning fast!)
- 🌟 OpenRouter (100+ models)
- 🏠 Local models (Ollama, LM Studio)
- 🤖 Gemini, OpenAI, Qwen and more

As a result, you can run this as a proxy and convert any app connecting to Anthropic to all other models. Anyway, have fun, star it ⭐, follow me, and share your experience!
