Node and graph editor controls for .NET desktop applications
Nodify.Avalonia is an open-source Avalonia control library for building node editors, graph editors, workflow designers, and visual programming tools in .NET desktop applications. It runs wherever Avalonia runs, including Windows, macOS, and Linux.
The library handles the editor surface, nodes, connectors, connections, selection, navigation, and input while your view models hold the graph data.
This library is an Avalonia port of Nodify, created by Miroiu Emanuel. These guides describe the Avalonia implementation maintained in the Nodify.Avalonia repository.
