This article explores how agentgateway was designed as a unified gateway to handle both AI and traditional API traffic through a single operational layer, with the author explaining that separate infrastructure stacks create unnecessary complexity. The Rust-based architecture achieves high performance while supporting emerging protocols like MCP and A2A, and the project was donated to the Agentic AI Infrastructure Foundation for vendor-neutral governance. With over 7 million downloads, agentgateway has achieved rapid adoption across enterprise environments.
