Kong or Kong API Gateway is a cloud-native, platform-agnostic, scalable API Gateway distinguished for its high performance and extensibility via plugins. It also provides advanced AI capabilities with multi-LLM support.

By providing functionality for proxying, routing, load balancing, health checking, authentication (and more), Kong serves as the central layer for orchestrating microservices or conventional API traffic with ease.

Kong runs natively on Kubernetes thanks to its official Kubernetes Ingress Controller.

Getting Started

If you prefer to use a cloud-hosted Kong, you can sign up for a free trial of Kong Konnect and get started in minutes. If not, you can follow the instructions below to get started with Kong on your own infrastructure.

Let’s test drive Kong by adding authentication to an API in under 5 minutes.

We suggest using the docker-compose distribution via the instructions below, but there is also a docker installation procedure if you’d prefer to run the Kong API Gateway in DB-less mode.

Whether you’re running in the cloud, on bare metal, or using containers, you can find every supported distribution on our official installation page.

1. To start, clone the Docker repository and navigate to the compose folder.

  $ git clone https://github.com/Kong/docker-kong
  $ cd docker-kong/compose/

2. Start the Gateway stack using:

  $ KONG_DATABASE=postgres docker-compose --profile database up

The Gateway is now available on the following ports on localhost:

• :8000 - send traffic to your service via Kong
• :8001 - configure Kong using Admin API or via decK
• :8002 - access Kong's management Web UI (Kong Manager) on localhost:8002

Next, follow the quick start guide to tour the Gateway features.

Features

By centralizing common API functionality across all your organization's services, the Kong API Gateway creates more freedom for engineering teams to focus on the challenges that matter most.

The top Kong features include:

• Advanced routing, load balancing, health checking - all configurable via a RESTful admin API or declarative configuration.
• Authentication and authorization for APIs using methods like JWT, basic auth, OAuth, ACLs and more.
• Proxy, SSL/TLS termination, and connectivity support for L4 or L7 traffic.
• Plugins for enforcing traffic controls, rate limiting, req/res transformations, logging, monitoring and including a plugin developer hub.
• Plugins for AI traffic to support multi-LLM implementations and no-code AI use cases, with advanced AI prompt engineering, AI observability, AI security and more.
• Sophisticated deployment models like Declarative Databaseless Deployment and Hybrid Deployment (control plane/data plane separation) without any vendor lock-in.
• Native ingress controller support for serving Kubernetes.

Plugin Hub

Plugins provide advanced functionality that extends the use of the Gateway. Many of the Kong Inc. and community-developed plugins like AWS Lambda, Correlation ID, and Response Transformer are showcased at the Plugin Hub.
