# Envoy AI Gateway Envoy AI Gateway is an [[Open Source]] [[AI Gateway]] built on Envoy Gateway and maintained by the CNCF Envoy community, with Bloomberg and Tetrate among the main contributors. It routes traffic from your applications to GenAI services through the infrastructure layer you probably already run on [[Kubernetes]]. Version 1.0 brought a committed-stable control-plane API, support for 16 providers ([[Anthropic]], [[OpenAI]], Google Gemini, Azure OpenAI, AWS Bedrock, Mistral, Cohere, DeepSeek, Groq and more), multimodal support, provider fallback and enterprise observability. It also acts as an [[Model Context Protocol (MCP)]] gateway, which is unusual in this category and increasingly relevant as agent tooling standardizes on MCP. ## Why it is interesting The governance is the feature. This is a vendor-neutral CNCF project rather than a company's open-core funnel, so the roadmap is not a lead-generation exercise for a hosted tier. If you have been burned by an open-source tool quietly moving its useful parts behind an enterprise license, that difference is worth real money. It expresses configuration through the Kubernetes Gateway API, so AI routing becomes another set of Kubernetes resources reviewed like any other. Platform teams tend to love this and application developers tend to find it heavy. Both reactions are correct, depending on where you sit. ## Compared to the alternatives [[LiteLLM]] is faster to stand up and friendlier for a single team. [[Kong AI Gateway]] fits organizations already on Kong. Envoy AI Gateway fits organizations whose platform is already Envoy and Kubernetes, where adding a separate AI proxy would mean two things to operate instead of one. ## References - Official website: https://aigateway.envoyproxy.io/ - Documentation: https://aigateway.envoyproxy.io/docs/ - Repository: https://github.com/envoyproxy/ai-gateway - Releases and changelog: https://github.com/envoyproxy/ai-gateway/releases ## Related - [[AI Gateway]] - [[Kubernetes]] - [[Open Source]] - [[Model Context Protocol (MCP)]] - [[Kong AI Gateway]] - [[LiteLLM]] - [[Model routing]] - [[Anthropic]] - [[OpenAI]]
