What do people build with it?

USE CASE 1

Run a single API gateway in front of many microservices for auth and rate limiting

USE CASE 2

Build an AI gateway that load balances and rate limits requests to multiple LLM providers

USE CASE 3

Terminate TLS and route HTTP, gRPC, WebSocket, and MQTT traffic from one entry point

USE CASE 4

Hot reload routes and plugins without restarting the gateway

How do you get it running?

Difficulty · hard Time to first run · 1h+

Needs an etcd cluster plus Nginx OpenResty, so production deployment is more involved than a single binary.

Apache 2.0 lets you use, modify, and ship APISIX commercially as long as you keep the license notice and patent terms.

In plain English

Apache APISIX is a cloud-native API gateway, which means it acts as a central entry point that sits in front of your services and manages all the traffic flowing in and out. Think of it as a smart traffic director: when a request comes in from a user or another system, APISIX decides how to handle it, routes it to the right backend service, applies security rules, limits how many requests a client can make, and collects monitoring data, all without you having to build any of that logic into your own applications. It is written in Lua and designed to be high-performance and fully dynamic, meaning you can update routes, add plugins, and change certificates while the gateway is running with no downtime. Beyond traditional API management, APISIX can function as an AI gateway, handling traffic to large language models with features like load balancing across multiple AI providers, token-based rate limiting, retries, and fallback logic. It supports a wide range of protocols including HTTP, gRPC, WebSocket, MQTT for IoT devices, TCP/UDP, and HTTP/3. Security features include authentication methods like JWT, key-based auth, and basic auth, as well as IP allowlists and blocklists. APISIX can run on bare metal servers, virtual machines, or Kubernetes and is licensed under the Apache 2.0 license.
