Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Kong Gateway

  • The free open-source gateway lacks the analytics, portals, and support of the paid Konnect tiers.
  • Plus tier caps API requests at 1M/month before incurring per-million overage charges.
  • Enterprise pricing is custom and not published, making budgeting harder without sales contact.
  • Configuration and plugin management can require significant operational expertise to run at scale.

Rancher

  • Another platform to run and keep available, and an outage in it affects access to everything it manages
  • Meaningful overhead if you only operate one or two clusters
  • Version compatibility between Rancher and managed Kubernetes versions needs watching during upgrades
  • Support requires a SUSE subscription; the project itself is community-supported
