Best When

You are running high-throughput AI workloads across multiple providers and need enterprise-grade failover, cost controls, and minimal latency overhead.

Avoid When

You only use one LLM provider and have no need for failover or multi-key load balancing.

Use Cases

  • Centralizing LLM API access across OpenAI, Anthropic, AWS Bedrock, Google Vertex, and Azure behind one endpoint
  • Achieving high availability with automatic failover when a provider goes down
  • Reducing LLM costs via semantic caching and intelligent load balancing across multiple API keys

Not For

  • Teams needing a managed SaaS gateway with vendor support — this is self-hosted
  • Simple single-provider setups where routing complexity adds unnecessary overhead
  • Non-Go shops that cannot maintain a Go service in production

Known Gotchas

  • Performance claims (11µs overhead, 50x faster than LiteLLM) are vendor-stated and not independently verified
  • MCP integration listed as a feature but limited documentation on how agents interact with it specifically
  • Self-hosted deployment requires maintaining Go service infrastructure
