Twisted Extrude is a Blender add-on from Mark Kingsnorth that extrudes faces with a twist, creating curled geometry such as pipes, tendrils, or more abstract effects through an interactive interface.

Zip Merge is a Blender addon that merges geometry together like a zip, joining vertices between mesh islands while preserving UVs. It targets cases where merge by distance or bridging faces cause problems.

Sculpt To Curve is a Blender add-on for sculptors and modelers that places ready-made, retopologized meshes onto editable splines. It ships with horns, tentacles, scales and chains you can shape in a few clicks.

Boolean Bevel Addon brings bevel-friendly boolean operations into Blender's SubD modeling. Built entirely with Geometry Nodes, it keeps every operation non-destructive and procedural, storing them as modifiers you can change or delete at any time.

LoopTools is a mesh modelling toolkit for Blender that gathers several tools to aid modelling. It was previously part of Blender 4.1's bundled add-ons and is now offered as an extension, provided as it is with limited support.

Extra Mesh Objects is a Blender add-on that expands the Add > Mesh menu with additional mesh object types. Previously bundled with Blender 4.1, it now ships as a standalone extension for Blender 4.2 LTS and newer.

MESHmachine is a mesh modeling addon for Blender focused on hard surface work without subdivision surfaces. It fuses and unfuses surfaces, creates variable fillets and washouts, edits bevels, and details meshes with plugs.

A.N.T.Landscape is a Blender add mesh add-on for generating landscapes and displacement. Originally a bundled add-on in Blender 4.1, it's now offered as-is with limited support, accessed from the View3D sidebar's Create tab.
