## What it is
Hummingbird is a lightweight, flexible web application framework and HTTP server written in Swift, built on top of SwiftNIO. It provides routing, middleware, TLS, HTTP2 support, and a minimal core extended through official packages for auth, Redis, Fluent ORM, WebSockets, and AWS Lambda.

## Use cases
- build a REST API backend in Swift
- serve HTTP endpoints with a lightweight Swift server
- create a web server with routing and middleware on Linux or macOS
- deploy a Swift backend to AWS Lambda
- add WebSocket support to a Swift server
- build low-memory high-throughput backend services

## When to choose
- you want a minimal, low-memory Swift server framework with few dependencies
- you need structured concurrency and predictable performance in Swift
- you want an SSWG-incubated alternative to Vapor with a modular extension ecosystem

## When to avoid
- your team does not use Swift or requires Swift 6.1+
- you need a batteries-included full-stack framework with built-in ORM and templating out of the box
- you need a non-HTTP protocol server
