Why This Project?

Why not use a local proxy, like Claude Code Router?

Local proxies only work on a single machine. This project serves multiple machines simultaneously.

Why not use LiteLLM?

LiteLLM requires a dedicated VPS, consumes more resources, and costs more to deploy.

Why no advanced features like routing or GUI management?

Built for personal use. Simplicity over features.

Not Suitable For

• Single-machine localhost proxy → Highly recommend Claude Code Router
• Enterprise/Team usage with GUI management → Use LiteLLM
• Advanced routing, load balancing, rate limiting → Use LiteLLM or similar
