God Mode Umbraco 8 Package Blog post

Diplo God Mode makes Umbraco developers invincible!

This custom tree for the Settings section of Umbraco 8 allows you to browse, query and search your document types and compositions; your templates and partials; your datatypes and property editors; your media library; your custom controllers and models. It provides diagnostics about your site and the server it is hosted on.

Note: This is the Umbraco 8 release. For the new Umbraco 9 version please read this blog post instead. And for the old Umbraco 7 version please read this blog post instead.

As a developer working with Umbraco you often need to be able to work out things like:

  • Which document types use this property editor? Or which use a specific instance (data type)?
  • What templates does this partial appear in?
  • Which document types use a specific property?
  • What are the largest items in my Media Library?
  • Which controllers does this site use and what type are they?
  • Which document types inherit from a given composition?
  • Which of my partials are cached and in what template?
  • How is Umbraco configured? How is my server configured?
  • What Controllers and Models are being used in the site?

God Mode is a developer tool for Umbraco that answers these questions. It is a complete rebuild of my Umbraco 7 version and has been rebuilt from scratch to work with Umbraco 8. It features a new UI and uses some fancy Umbraco 8 features such as D.I. etc. Under the hood a lot has changed in Umbraco 8, so this required changing almost every element that interacted with Umbraco services and the various datalayers.


  • Easily see which document types inherit from any of your compositions
  • See which document types use which property editor or data type instance
  • See which partials are used by all your templates and which of those are cached
  • Find out which data types are being used (or not!)
  • Browse all media in the Media Library and sort it by file type, size or media type
  • See which controllers (Surface, API and RenderMvc) are being used and in what namespaces and DLLs
  • View all generated models (that inherit from PublishedContentModel)
  • Browse all Umbraco Settings, plus all Server settings and MVC settings
  • Look at any assembly in your site and see which types implement a particular interface
  • Plus lots more!

Is it possible to run the "Warm Up" feature automatically on startup?

Hi Liam,

It's not possible out-of-the-box with my package. However, there is an API controller endpoint you can call that will return you a list of distinct page URLs (as JSON) you could warm-up yourself. The endpoint would be:


It would only work for people logged into the backend with access to the Developer section.

Alternatively, you can call this in C# via the:



So you could hook into Application startup, get a list of these items and

then use an HTTPClient to "ping" each URL:
