The models' case: CNCF project built directly on Envoy with Gateway API as its native, first-class config surface (not a bolt-on), making it the reference implementation platform teams. The models' main caveat: Younger control plane with a thinner out-of-box extension/plugin catalog than Kong. The strongest alternative is Kong Gateway — Deepest plugin ecosystem (auth, rate limiting, transformations, observability) and the most mature enterprise story — Konnect control plane, RBAC.
