Claude Code Proxy

Claude Code Proxy is a proxy server that enables Anthropic clients to interact with Gemini, OpenAI, or Anthropic backends by translating API requests via LiteLLM.

The Claude Code Proxy functions as a bridge that allows users to connect Anthropic-compatible clients to non-Anthropic backends. It receives requests in the standard Anthropic API format and uses LiteLLM to translate these calls into compatible formats for OpenAI or Gemini models. Users configure the server via environment variables to map Anthropic's Sonnet and Haiku models to specific OpenAI or Gemini alternatives. It handles both streaming and non-streaming responses to ensure compatibility with Claude clients. The software is available for deployment from source or as a Docker container, offering flexibility in how the proxy infrastructure is integrated into developer workflows.
