deepseek-router

DeepSeek Router is a production-grade proxy designed to provide high availability for Claude Code by routing requests through multiple AI providers. It acts as a drop-in replacement for the Anthropic Messages API, supporting five major Chinese providers: DeepSeek, Tencent Hunyuan, Zhipu GLM, Alibaba Bailian, and ByteDance Volcengine. The router features automatic failover with sub-1ms latency, circuit breaking to isolate failing endpoints, and zero-downtime configuration reloads. It includes a health monitoring dashboard, Prometheus metrics, and security features like rate limiting and request validation. By aggregating multiple providers, it offers a cost-effective alternative (7-34x cheaper than official APIs) with significantly improved uptime (~99.99%) compared to single-provider setups. The system handles the translation between the Anthropic format and various provider-specific OpenAI-compatible formats, ensuring seamless integration with existing tools.
