    Architecture

UniClaudeProxy is a lightweight, high-performance FastAPI proxy that lets Claude Code talk to any LLM backend — OpenAI-compatible APIs, Google Gemini, DeepSeek, GLM, Ollama, or Anthropic passthrough. Drop it in as your API endpoint and use whatever model you want with Claude Code's full tool-calling capabilities.
I wanted a quick way to use all the models in Claude Code without being locked to a single provider. So I built one of the best proxies out there — fast, modular, and packed with features that just work.

If this project is useful to you, consider giving it a star. It helps others find it.

Why UniClaudeProxy?

- Use any model with Claude Code — DeepSeek, GLM, Ollama, Gemini, or any OpenAI-compatible API
- Zero changes to Claude Code — just point the API URL to localhost:9223
- Full tool calling support — native function calling + ReAct XML fallback for models without it
- Streaming first — real-time SSE streaming with proper Anthropic event format
- Production ready — hot-reload config, image support, thinking/reasoning blocks, custom headers
- Secure by default — local-only mode blocks all non-localhost connections out of the box
