    ServiceStack

    ServiceStack

    Simple, fast, versatile and full-featured services framework

    One framework to power them all. Write your HTTP APIs once and take advantage of end-to-end typed integrations for all popular web, mobile and desktop platforms. 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. 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.
