A proxy that lets Claude Code and Agent SDK use domestic Chinese LLMs (DeepSeek, Qwen, GLM, MiniMax, Kimi) as backend

deepseek-proxy

deepseek-proxy is published on npm as @sunflower0305/deepseek-proxy. It is a lightweight Express proxy that lets Claude Code or the DeepSeek Agent SDK talk to domestic Chinese LLM providers through Anthropic-compatible /v1/messages endpoints.

It currently supports qwen, deepseek, glm, minimax, and kimi.

Install

Run without installing:

npx @sunflower0305/deepseek-proxy

Or install globally:

npm install -g @sunflower0305/deepseek-proxy
deepseek-proxy

Configure

The proxy reads configuration from environment variables. You can export them in your shell or create a .env file in the directory where you run deepseek-proxy.

Example .env:

PROVIDER=qwen
PROXY_PORT=8080
QWEN_API_KEY=your-qwen-api-key
QWEN_MODEL=qwen-plus

Available variables:

You can use the bundled example as a starting point:

cp node_modules/@sunflower0305/deepseek-proxy/.env.example .env

If you installed globally, create .env manually or export the variables in your shell before starting the proxy.

Start The Proxy
