Open-source and cloud API gateway for managing microservices traffic
Overview
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.
The honest half
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.
Cross-shopped
Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Softwr does not host reviews and shows no star rating for Kong Gateway, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
