Overview

What Kong Gateway does

Kong Gateway is an API gateway used to route, secure, and observe traffic between clients and backend microservices. It is available as a free open-source gateway and as part of Kong Konnect, a managed cloud platform that adds developer portals, an AI gateway, analytics, and enterprise support. Kong supports plugins for authentication, rate limiting, transformation, and logging across hybrid, dedicated cloud, and self-managed deployments.

What people use it for

  • Routing and securing traffic across microservices
  • Publishing internal or external developer portals
  • Managing rate limits and authentication at the API edge
  • Gateway-level routing to multiple LLM providers

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about 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.
