Sitecore Host is a common platform for all Sitecore services, introduced in Sitecore 9.1.


A Sitecore service is a piece of functionality or a feature that runs separately, outside of the main Sitecore CM or CD role.

Sitecore Host acts as a base for a service and it addresses a number of common concerns. It also allows dynamic extensibility of services through the use of Sitecore Host plugins.

Sitecore Host has the following features:

  • Unified service registration (DI)

  • Unified configuration

  • Unified file system access

  • Command-line actions

  • Global route registration

  • Dynamic plugin loading

  • Sitecore consumption-licensing ready

  • Cross-platform ready (Sitecore Host is based on the latest Microsoft .NET Core libraries)


    Sitecore Host requires version 2.1 of .NET Core.

The advantages of running any feature or service built on Sitecore Host are:

  • All Sitecore Host applications have a consistent experience. For example: logging works the same way across any Sitecore Host application, configuration is merged and patched in the same way, command-line options all work in the same way, and so on.

  • The installation experience is consistent.

  • You can configure applications on the command line, without need for a UI.

  • You have powerful extensibility options through host plugins, so you can extend a feature with additional functionality.

  • The host behaves the same way whether you run it in the cloud or on premise, on Windows or on Linux, on dedicated hardware or inside a container.

A Sitecore Host plugin is a extensibility unit that you can load into a Sitecore Host application dynamically, without having to change or recompile any part of the base code.

Sitecore Host always loads plugins in dependency order . It applies code loading, configuration overrides, and so on, in that same dependency order.

A plugin can contain the following elements:

  • Code - register services (dependency injection), register routes, and run your C# code.

  • Configuration - include, override, or provide new configuration.

  • Commands - add new commands, arguments, and subcommands.

  • Content - include any file system files (JavaScript, images, and so on).
