Learn about agentgateway, its purpose, and core concepts.

Agentgateway is an AI-first, open-source, cloud-native gateway control plane and proxy data plane, that was originally donated to the Linux Foundation in 2025 and was accepted as an Agentic AI Foundation (AAIF) project in 2026.

It is a general-purpose HTTP and gRPC data plane with load balancing, timeouts, retries, TLS, rate limits, authorization, and traffic policies. You can also front ordinary APIs and microservices with the same proxy that you use for LLM inference, MCP tool servers, and A2A agent traffic. This way, you do not need to operate separate “regular” and “AI” gateways. On that foundation, it focuses on implementing the missing pieces not found in traditional API gateways to support MCP and agentic workloads at scale. The project emphasizes enterprise-grade security, observability, resiliency, reliability, and multi-tenancy features. Agentgateway is built to be the most performant, reliable, and mature LLM/MCP agentic gateway on the market.
