Node Arranger

This extension was previously bundled with Blender 4.1. It has now been completely rebuilt, with major improvements.

Node Editor -> Sidebar -> Arrange

Organise your nodes with this auto-layout add-on. No matter the node tree complexity, nodes will be pleasingly arranged, organised, and aligned. You choose what to arrange – select specific nodes or the whole node tree. Adjust settings like spacing to suit your taste.
