What is an API gateway?
An API gateway sits in front of your APIs and handles the cross-cutting concerns — routing, authentication, rate limiting, and observability — so each service doesn't reimplement them. Larger products add full API management: developer portals, quotas, and monetization.
As APIs and microservices multiply, a gateway centralizes security and traffic control in one place. The choice is often architecture-led (cloud-native vs self-hosted vs enterprise management), and it becomes the front door every request passes through — hard to swap later.
How to choose
What separates the API Gateway options.
Managed gateways remove ops; open-source self-hosted ones give control and avoid lock-in.
A lightweight gateway routes and secures; full API management adds portals, quotas, and analytics.
Latency added per request matters at scale; some gateways are far lighter than others.
REST, gRPC, GraphQL, and WebSocket support decide what you can put behind it.
Best API gateway for your use case
| If you need… | Reach for | Why |
|---|---|---|
| AWS / serverless | AWS API Gateway | Native gateway for Lambda and AWS services. |
| Open-source, self-host | Kong / Apache APISIX | Fast, extensible gateways you run yourself. |
| Enterprise API management | Apigee | Full lifecycle management — portals, quotas, monetization. |
| Lightweight, cloud-native | Tyk | Open-source-friendly gateway and management. |
API Gateway: incumbents vs new entrants
The space ranges from enterprise API-management suites to cloud-native managed gateways and fast open-source projects you self-host.
Why AI agents decide this category
An API-gateway pick is usually architecture-led, which makes the agent's recommendation a real fork: does it default to the cloud-native managed option that matches the rest of the stack, or surface an open-source gateway? The front door it names tends to stay the front door.
Frequently asked questions
What is an API gateway?
A layer in front of your APIs that handles routing, authentication, rate limiting, and observability so each service doesn't reimplement them. Larger products add developer portals, quotas, and monetization.
What is the best API gateway?
AWS API Gateway for serverless/AWS, Kong or Apache APISIX for open-source self-hosting, Apigee for enterprise API management, Tyk for a lightweight option. The ranking above shows which AI agents pick.
Kong vs Apigee vs AWS API Gateway?
Kong is an open-source/commercial gateway you can self-host; Apigee is full enterprise API management; AWS API Gateway is the managed, AWS-native option. The Pick Rate shows how agents weigh them.
Is there an open-source API gateway?
Yes — Kong and Apache APISIX are open-source and self-hostable, and Tyk has an open-source core.
