KumikoUI - A Free, Open-Source DataGrid for .NET MAUI

The paid DataGrid options for MAUI are expensive, and the free ones stop short of the features that business applications actually need. KumikoUI is Michael Stonis’s answer: a fully canvas-drawn DataGrid using SkiaSharp, delivering identical, pixel-perfect output across iOS, Android, macOS Catalyst, and Windows.

What you will learn

• Why a canvas-drawn approach was chosen over native controls, and the tradeoffs involved
• The feature set: filtering, grouping, summaries, inline editing, frozen columns/rows, drag-and-drop reorder
• How the rendering is abstracted behind an IDrawingContext interface, with KumikoUI.Core having zero dependency on MAUI or SkiaSharp — making future ports to UNO or Blazor possible
• How to get started via the NuGet package
• How to explore the sample app including a 100K-row stress test
