Service Stack is a high-performance .NET web services platform that simplifies the development of high-performance REST (JSON, XML, JSV, HTML, MsgPack, ProtoBuf, CSV) and WCF SOAP Web Services.

Simple REST service example

This example is also available as a stand-alone integration test:

//Web Service Host Configuration
public class AppHost : AppHostHttpListenerBase
    public AppHost() : base("TODOs Tests", typeof(Todo).Assembly) {}

    public override void Configure(Container container)
        container.Register(new TodoRepository());

//REST Resource DTO
public class Todos : IReturn<List<Todo>>
    public long[] Ids { get; set; }
    public Todos(params long[] ids)
        this.Ids = ids;

[Route("/todos", "POST")]
[Route("/todos/{Id}", "PUT")]
public class Todo : IReturn<Todo>
    public long Id { get; set; }
    public string Content { get; set; }
    public int Order { get; set; }
    public bool Done { get; set; }

public class TodosService : Service
    public TodoRepository Repository { get; set; }  //Injected by IOC

    public object Get(Todos request)
        return request.Ids.IsEmpty()
            ? Repository.GetAll()
            : Repository.GetByIds(request.Ids);

    public object Post(Todo todo)
        return Repository.Store(todo);

    public object Put(Todo todo)
        return Repository.Store(todo);

    public void Delete(Todos request)

Calling the above TODO REST service from any C#/.NET Client

//no code-gen required, can re-use above DTO's

var restClient = new JsonServiceClient(BaseUri);
List<Todo> all = restClient.Get(new Todos());     		// Count = 0

var todo = restClient.Post(
    new Todo { Content = "New TODO", Order = 1 }); 	    // todo.Id = 1
all = restClient.Get(new Todos());						// Count = 1

todo.Content = "Updated TODO";
todo = restClient.Put(todo);							// todo.Content = Updated TODO

restClient.Delete(new Todos(todo.Id));
all = restClient.Get(new Todos());						// Count = 0

Calling the TODO REST service from jQuery

$.getJSON(baseUri, function(todos) {
	alert(todos.length == 1);

Calling the TODO REST service from Dart JsonClient

var client = new JsonClient(baseUri);
	.then((todos) => alert(todos.length == 1) ); 

That's all the application code required to create a simple REST web service.

Getting Started


If you have NuGet installed, the easiest way to get started is to install ServiceStack via NuGet:

ServiceStack with Razor Support: Create an empty ASP.NET Web or Console Application and (.NET 4.0+) Install-Pacakage ServiceStack.Razor2

ServiceStack binaries only: Minimal installation of ServiceStack containing only the core-binaries (.NET 3.5+) Install-Pacakage ServiceStack

Starter templates with pre-configured AppHost and basic Hello World REST services

If you just want ServiceStack hosted at / - Create an empty ASP.NET Web Application and Install-Pacakage ServiceStack.Host.Mvc

Otherwise if you want to host ServiceStack Side-by-Side with MVC: Hosted at /api - Create an empty MVC Web Application and Install-Pacakage ServiceStack.Host.Mvc

To help get started you should also clone the ServiceStack.Examples projects (includes dlls, demos and starter templates):

git clone git://

Alternatively if you want keep up with the latest version and not use NuGet, simply clone this repo:

git clone git://

Download published NuGet binaries without NuGet

GitHub has disabled its download feature so currently NuGet is the best way to get ServiceStack published releases. For environments that don't have NuGet installed (e.g. OSX/Linux) you can still download the published binaries by extracting them from the published NuGet packages. The url to download a nuget package is:{PackageName}/{Version}

So to get the core ServiceStack and ServiceStack.Text libs in OSX/Linux (or using gnu tools for Windows) you can just do:

wget -O ServiceStack
unzip ServiceStack 'lib/*'

wget -O ServiceStack.Text
unzip ServiceStack.Text 'lib/*'

which will download and extract the dlls into your local local lib/ folder.
