Node Align is a Blender add-on from W_Cloud that gathers node alignment into a single pie menu, opened with Shift+Q or Ctrl+Q. It offers a broad set of alignment methods rather than a single command.
You can align nodes to the left, right, top, or bottom, match their height or width, and distribute them vertically, horizontally, or evenly by height and width. Grid options include relative and absolute grid distribution, along with changing the number of rows or columns and setting custom spacing. A straighten-links option cleans up the connections between nodes. Node Align can align nodes together with a frame, though it can't align a frame on its own.
The add-on works with Blender 4.2 LTS and newer, is released under the GNU General Public License v3.0 or later, and requires no special permissions. Version 3.2.6 fixes a socket-location error seen in Blender 5.2 on macOS.
