Why ServiceStack?

Simple, versatile, evolvable, resilient high-performance message-based APIs

Maximize Value and Reach of System APIs

ServiceStack's primary goal is to enhance the value of System APIs which serve as the blueprint that most features centered around. By using simple & pure dependency-free DTO models decoupled from any implementation we're free to continue layering on features which now sees ServiceStack APIs as the most versatile in the world where the same high-performance APIs can be consumed from HTTP in any combination of Route, QueryString, FormData or a myriad of data formats, via popular resilient MQ Servers whilst simultaneously supporting legacy integrations like SOAP or adopting new technologies like gRPC without sacrificing any native HTTP integrations.

Ultimate Developer Productivity

To maximize the value of APIs we're focused beyond the API boundary by making it as simple as possible for API Consumers to call your APIs, thereby making them more appealing and creating multiplicative value with the time & effort saved by each API consumer.

In addition to providing native end-to-end typed integrations to 9 of the most popular languages used in creating Web, Mobile & Desktop Apps, we also maintain IDE plugins for most major IDEs enabling your API Consumers to easily add/update typed API Service References from within Rider, VS.NET, Android Studio, PyCharm, IntelliJ IDEA, RubyMine, Php/WebStorm & Eclipse.

Remote Services Best Practices

The best approach for achieving its goals of capturing a systems functionality in a typed Service contract that yields the most reusable & evolvable API design was to adopt a message-based design that embraces the revered SOA Integration Patterns best-practices by realizing its Remote Facade, Data Transfer Object and Service Gateway patterns whose benefits positions ServiceStack in a rarefied breed of frameworks to enable optimal end-to-end typed API integrations without code-gen as the same dep-free Service Models used to define its APIs can be used as-is in .NET Apps.

Benefits of message-based design

Unlike RPC, messages can be evolved, intercepted, routed, decorated & serialized with natural decoupling of an APIs coarse-grained DTO contracts from its implementation allowing front & back-end developers to collaborate on an agreed high-level API design free of detail concerns, before using the contract-first DTOs to independently implement any required functionality.

It allows client logic to bind to impl-free service client interfaces that can be easily substituted from a test client returning mock data to utilizing any of the many available .NET generic Service Client implementations including gRPC.

Consistent & Simplified Development Model

The benefit afforded by capturing an entire API boundary into impl-free Service Contracts extends to all natively supported languages who only need be concerned with generating declarative DTOs resulting in types encapsulating richer metadata beyond what's possible with restrictive primitive types found in other code-gen solutions like Open API.

It enables teams across disciplines and languages to work the same way when integrating internal or external applications or tools. This reduces software maintenance efforts and enables developers to focus on the important part of their code rather than the plumbing between client & server.

Preserve Investments

From its outset ServiceStack has been consistently promoting the same remote service best-practices for over a decade, whose adoption of its time-tested patterns has survived beyond several abandoned .NET Web Service frameworks, iterations & programming models during its lifetime with any investments in them having failed along with them.

Instead of enduring wasted investments through constant rewrites, ServiceStack APIs have in contrast remained constant whilst gaining value over time, continuing to add support for more languages, typed clients, IDE integrations, endpoints, data formats & .NET Hosts.

Add ServiceStack Reference

Generate Native Types for your preferred language and platforms directly from within your favorite IDE or easy to use CLI tooling.

Add and update lightweight client code straight from the server you integrate with giving you an easy to use end-to-end typed interface with your ServiceStack server.


Surface the ideal API a developer would naturally write and complete their implementation for them with AutoQuery!

AutoQuery which utilizes conventions to automate the creation of intent-based self-descriptive APIs that are able to specify configurable conventions and leverage extensibility options for a great developer experience.


Use ServiceStack Studio to manage Users, Validation, Permissions and Data with our portable tool for your AutoQuery services.

ServiceStack Studio is a capability-based UI to manage multiple remote ServiceStack instances from either a Chromium Desktop App or cross-platform .NET Core Web App.

Smart Typed Clients

Ultimate simple typed client integrations utilizing resilient message-based APIs and Rich POCO DTOs


Reuse your future-proofed ServiceStack APIs to reach gRPC's efficient typed universe

AutoGen CRUD

Generate fully featured web services dynamically from your RDBMS of choice with ease allowing you to un-silo your valuable data.

AutoGen for AutoQuery generates the required DTO types at runtime, and ServiceStack tooling allows you to extract those runtime types, giving you a future proof pathway to customize and migrate to a code-first model when you need.

Mobile Clients

First class client libraries for your favorite Android and iOS development frameworks, working in your preferred language.

Smart Typed Clients simplify integration, with the ability to use generated DTO classes to created a typed end-to-end integration with any ServiceStack application.

Jupyter Notebooks

Jupyter is an exciting initiative to support an open standards, language agnostic interactive computing platform where it provides the ideal integrated exploratory programming environment for data science and scientific computing.

We've fully embraced this new paradigm with effortless UI and command-line tools for generating pre-populated Python, C# and F# Jupyter Notebooks

Post Command line HTTP API tools

Post Command is a collection of command line utils that lets you easily discover, inspect and invoke ServiceStack endpoints from a single command.

Use inspect to discover features and APIs available on a remote ServiceStack endpoint including the version of ServiceStack running, the App’s registered Content Types, Plugins and Auth Providers as well as its public APIs, their routes and Response Types.

Then use send to invoke any ServiceStack API with just its name and a JavaScript Object literal to view the response in a human-friendly markdown view or as JSON or including raw HTTP Request & Response Headers.

ServiceStack gRPC

Create gRPC services in a consistent way to all your other services or easily add gRPC support to your existing ServiceStack services.

ServiceStack’s gRPC support enables a highly productive development environment for developing high-performance gRPC HTTP/2 Services by making ServiceStack’s existing typed Services available from ASP.NET’s gRPC endpoints.
