## What it is
Vapor is a server-side HTTP web framework written in Swift, built on SwiftNIO with a non-blocking, event-driven architecture. It includes an ecosystem of packages such as Fluent (ORM), JWT (authentication), Leaf (templating), and WebSocketKit, enabling full backend, API, and web app development in Swift.

## Use cases
- build a REST API in Swift
- create an HTTP server backend for an iOS app team
- serve JSON endpoints with routing and middleware
- build a website with server-side templating
- add JWT authentication to a Swift backend
- query a database with an ORM without writing SQL
- handle websocket connections server-side

## When to choose
- your team already knows Swift and wants to reuse it for the backend
- you want a type-safe, performant, async/await-based web framework
- you need a full-stack Swift ecosystem including ORM, JWT, and templating

## When to avoid
- your team primarily works in another language and has no Swift expertise
- you need a framework with a much larger middleware/job-market ecosystem like Node or Rails
- you rely on libraries or hosting tooling that only support mainstream server languages
