Free, open source.
A toolbox of things I have built and given away over the years. Five projects, one page. Pick what you need.
Sitefinity MCP Server.
Give Claude, Cursor, and other AI assistants direct access to your Sitefinity instance. Read logs, inspect modules, explore content types, and switch environments without leaving your editor.
The GetRelatedItems() call is failing because the taxonomy field "Category" returns null when no categories are assigned. You need a null check before the .Select() call.

Sitefinity Assembly Scanner.
Makes every Sitefinity build about 5 seconds faster. Feather's built-in widget scan loads every DLL in bin into a CLR just to read two attributes. This native executable reads the same metadata directly, with byte-identical output.
// ~125x faster, byte-identical output
That is the whole install. The package ships an MSBuild targets file that points Sitefinity's build step at the executable. No PowerShell, no .NET runtime on build agents, nothing to add to your .csproj.

Using React? Same calendar.
big-calendar-react is the React port with the same 5 views, event CRUD, user filtering, and dark mode. Built with shadcn/ui and Tailwind CSS, with zustand in place of Pinia.
Sitefinity widgets.
Production-ready, drag-and-drop widgets for the Sitefinity page editor. RandomSiteControls is the de-facto open source extension pack for the platform.
Tabstrip
Drag-and-drop widgets into a native Bootstrap or Kendo tabstrip. The only tabstrip component for Sitefinity that allows hosting any content.
Html Content Block
Enter content in a full-screen instance of VSCode in the browser, with intellisense and syntax highlighting. No content parsing, this thing is fast.
Markdown Editor
Enter content as markdown with a live preview. Cleaner than wysiwyg editors that bloat markup.
Page Title
Drop on the top of a page to pull in the title automatically, or edit to change. Template is global so you can restyle site-wide without editing 1000 content blocks.
Google Maps
Drag-and-drop Google Maps widget, with just about every option configurable in the designer.
Widget Finder
Find which pages contain which widgets, including layouts. Search across the entire site.
Plus a pile of extension methods.
Helpers like .GetTags(), .GetImage(), .Live(), .Master() and many more, to keep your Sitefinity code short and readable.
// content extensions
var tags = content.GetTags();
var image = content.GetImage();
var live = content.Live();// query extensions
var master = query.Master();
var published = query.Published();
var visible = query.Visible();ServiceStack templates.
The fastest way to create custom Sitefinity services. Skip MVC JsonResults and Webforms svc calls. ServiceStack is fully licensed by Sitefinity.
Plain C# template: a basic structure for creating ServiceStack API endpoints in Sitefinity, with dependency injection and service registration ready to go.
CodeRush template: quickly generate ServiceStack endpoints with proper error handling and documentation.
