| deployment.options | `{"cloud":true,"hybrid":true,"on_prem":true,"self_hosted":true}` | `{"cloud":true}` |
| description.long | An open-source gateway built on Envoy that centralizes AI traffic management by forwarding OpenAI-compatible requests to various LLM providers with automatic failover, token-based rate limiting, and Kubernetes-native deployment. | A model routing service for coding agents that uses machine learning to predict and recommend the most cost-effective and accurate AI model for each request. Engineering teams typically achieve 20-40% cost savings without quality degradation through continuous learning from real usage patterns. |
