Top 10 API Gateway

API gateway tools manage, secure, and observe APIs by providing routing, authentication, rate limiting, transformation, and developer portal capabilities at the edge of services.

Why this category matters

Exposing APIs without a gateway layer creates security, observability, and management gaps. API gateways centralize cross-cutting concerns like authentication, throttling, and logging, reducing duplication across services.

When to use these tools

Deploy an API gateway when exposing services externally or across teams, when you need centralized authentication and rate limiting, or when a developer portal is needed for API consumers.

API Gateway — FAQ

What is the difference between an API gateway and a service mesh?

An API gateway handles north-south traffic (external clients to services) and focuses on API management. A service mesh handles east-west traffic (service to service) and focuses on network reliability and security.

What is Kong and how does it compare to Apigee?

Kong is an open-source, plugin-based gateway that runs anywhere from bare metal to Kubernetes. Apigee is a Google Cloud-managed platform with stronger API lifecycle management, analytics, and monetization features.

Can API gateways handle GraphQL as well as REST?

Yes, modern API gateways like Kong, Tyk, and AWS API Gateway support GraphQL proxying and introspection alongside REST and gRPC endpoints.
