VERDICT

Should I use agentgateway?

The open-source gateway for AI traffic — LLM, MCP, A2A, and HTTP in one data plane. - agentgateway.dev

Depends. Buy it if you are a platform team governing multi-agent MCP/A2A traffic and LLM spend on Kubernetes. Skip it if you just proxy one provider's API — LiteLLM or direct SDK calls are far simpler.

Confidence

Medium. Based on ~20 public sources; no third-party user ratings or verbatim review quotes beyond practitioner posts.

Best for

  • Platform teams running many AI agents
  • Kubernetes-native engineering orgs
  • MCP/A2A tool governance at scale
  • Multi-provider LLM cost control

Not for

  • Solo devs calling a single LLM API — massive overkill
  • Teams without Kubernetes or platform engineering capacity
  • Buyers wanting managed SaaS with vendor SLAs on day one
  • Projects needing only API-key rotation or basic rate limits
