Swift, but on a server

Vapor provides a safe, performant and easy to use foundation to build HTTP servers, backends and APIs in Swift

import Vapor

let app = try await Application.make(.detect())

app.get("hello") { req in
    "Hello, world!"
}

try await app.execute()

Build server side with the tooling you already understand

No need to learn a language from scratch (or assemble a different team) just for your backend. Vapor is built on Apple’s SwiftNIO so you’ll get to use the language you already know and love.

High-performant APIs and servers

Built with a non-blocking, event-driven architecture, Vapor allows you to build high-performant, scalable APIs and HTTP servers. Using Swift's Concurrency model, you can write clear, maintainable code that's efficient and easy to read.

app.get("todos", ":id") { req async throws -> Todo in
  let id: UUID = try req.parameters.require("id")

  guard
    let todo = try await Todo.find(id, on: req.db)
  else {
    throw Abort(.notFound)
  }

  return todo
}

Ship with confidence, even on Fridays

With Vapor's expressive, protocol oriented design, you'll have peace of mind when shipping your code. With our strong type-safety focus, many errors and problems are caught early on by the compiler.

func search(req: Request) async throws -> [Todo] {
  let name: String = try req.query.get(at: "name")

  let results = try await Todo.query(on: req.db)
    .filter(\.$number == name)
    .all()

  return results
}

Binary operator '==' cannot be applied to operands of type 'KeyPath<Todo, FieldProperty<Todo, Int>>' and 'String'
