What it is
Vapor is an HTTP web framework for Swift, the language Apple created. It gives developers a foundation for building websites, APIs, and cloud services that run on the server rather than on a user's device. The README describes it as aiming to be expressive and easy to use.
- Build a JSON API backend for a mobile app written in Swift
- Serve a website or web application over HTTP
- Create cloud services that handle HTTP requests and responses
Great for
- Swift developers who want to build backend services in the same language as their iOS or macOS apps
- Teams building JSON APIs or web backends who already work in Swift
- Developers interested in server-side Swift who want a widely used, community-backed framework
Not ideal for
- People with no Swift experience, since the framework assumes Swift knowledge
- Teams that need the latest stable release, because the newest listed release is a beta (5.0.0-beta.4)
- Projects that depend on a mature ecosystem of libraries in another language, such as Python or JavaScript
How to get it
- 1
Clone and build from source
You'll need: Swift 6.0+
Clone the repository
git clone https://github.com/vapor/vapor.git - 2
Run it
- Install Swift 6.0 or newer
- Clone the repository and open it in a Swift-capable environment
- Read the documentation at docs.vapor.codes to set up a first project
- Ask questions in the Vapor Discord if you get stuck
- 3
Get the most out of it
- Read the official documentation at docs.vapor.codes for guided setup and examples
- Browse the awesome-vapor community list to see projects built with the framework
- Join the Discord community to get help from other developers
- Check the GitHub issues page before reporting a bug or proposing a feature
Downloads
Strengths
- Open source under the MIT license, free to use and modify
- Actively maintained, with a recent push and a large star count on GitHub
- Has an official Discord community and documentation site linked from the README
Trade-offs
- The README lists Swift 6.0+ as a requirement, so older Swift setups will not work
- The latest release is a beta, so the API may still change before a stable version
- The README is truncated and does not show detailed setup steps, so the entry relies on limited install information
