Agent Router (EAIG) versus LiteLLM comparison
Open Source

Agent Router (EAIG)

A Kubernetes-native AI gateway built on Envoy Proxy, extending the Gateway API with AI-specific routing, security, and observability.

✔High-performance Envoy data plane
✔Native Gateway API alignment
✔Extensible via enterprise plugins
Open Source

LiteLLM

An LLM proxy and gateway library focused on unifying access to multiple model providers behind an OpenAI-compatible API.

✗No native Kubernetes Gateway API integration
✗Not built on the Envoy Proxy data plane
✗No built-in enterprise plugin ecosystem for security or governance
✗Limited distributed tracing compared to a full data-plane deployment
