{"slug":"best-api-gateway-for-kubernetes","title":"Best API gateway for Kubernetes","question":"What are the best API gateway for Kubernetes?","verdict":"As of 2026-07-15, ChatGPT, Claude, Gemini and Grok collectively rank Envoy Gateway #1 for api gateway for kubernetes on ModelsAgree by aggregate score. The models' case: The CNCF-backed reference implementation of the Kubernetes Gateway API on the Envoy proxy — after the ingress-nginx retirement (maintenance ended March 2026) it became. The models' main caveat: Still gateway/traffic-layer focused — no developer portal, API monetization, or deep API lifecycle management. The strongest alternative is Kong — Best overall balance of mature Kubernetes/Gateway API integration, extensive authentication and traffic-policy plugins, strong declarative automation. Not unanimous: ChatGPT picks Kong; Grok picks Kong.
