What is agentgateway?

agentgateway review covering its open-source LLM, MCP, A2A, HTTP and gRPC gateway, security controls, deployment tradeoffs, pricing, pros, cons, and use cases.

agentgateway is an open-source data plane for conventional service traffic and AI-native protocols. Its official homepage describes routing and governance for HTTP, gRPC, TCP, major LLM providers, self-hosted inference, Model Context Protocol traffic, and agent-to-agent communication. The appeal is consolidation: a platform team can apply routing, policy, observability, and cost controls without operating a separate gateway for each traffic type. It remains infrastructure software, so production value depends on deployment design, identity integration, policies, monitoring, and safe operations.
