Agentgateway

Agentgateway is worth evaluating first if you already operate multi-model, MCP, or agent traffic; it is usually not the first pick if you only want to ship a single simple agent app quickly. The strongest evidence here is the official GitHub repo and release posts, which support its positioning as an AI traffic gateway. X reposts and “tool of the week” mentions show attention, not broad proof of production quality by themselves.

It is not a generic API management suite, and not a no-code agent builder. A better comparison is “an API gateway extended for LLM, MCP, and A2A workloads.” The available evidence points to unified ingress, routing, security, observability, and governance. Official posts mention virtual model routing, token and dollar cost tracking, reusable providers and guardrails, plus federating multiple MCP servers into one endpoint with scoped tools. That suggests platform-control capabilities rather than a product that directly builds business agents for you.

The adoption bar is closer to infra engineering than app scripting: you likely need to understand proxy layers, auth, model routing, policy rules, and existing service topology.
