I was looking for a way to automatically arrange my nodes similar to how Houdini does it and found out about this add-on already in blender called Node Arrange. It works pretty well for now since I currently use very few nodes but it still has some issues and looking at its Github, it hasn’t been updated in 4 yrs. Do you know any other free alternatives to this add-on?
You can try this one ( FREE)…I haven’t tried it in 3.++ as yet, but works well with 2.92-2.93 There are no 1-click solutions or auto-arrange as far as I know.
Here are some pics (Had to do it in individual post since I am a new user and can only post 1 embedded media in a post):
This is what it looks like arranging them manually
