Blender Addon Database
Introduction​
Addons extend Blender. They run inside the application you already use, and they work directly on your scene: new panels, new importers, and new analysis tools for your 3D data.
This database covers the addons that matter for visual investigation. The pages do not go deep into every feature. They focus on the workflow: how to get the information you need out of your data quickly and accurately, and how to document the process.
Use the search bar to filter by name, category, or tags. For separate software that runs outside Blender, see the Tools Database.

Essential Built-in Addons
These addons are built into Blender but disabled by default. We recommend enabling them for a smoother workflow. They are general-purpose tools that improve the overall Blender experience.
Node Wrangler​
Category: Workflow | Installation: Edit > Preferences > Add-ons > Search "Node Wrangler"
Essential for node-based workflows. Provides shortcuts for connecting, previewing (Ctrl+Shift+Click), and managing nodes in the Shader and Geometry Node editors. It also allows for instant texture setup (Ctrl+Shift+T).
Modifier Tools​
Category: Interface | Installation: Edit > Preferences > Add-ons > Search "Modifier Tools"
Adds "Apply All", "Delete All", and "Viewport Vis" buttons to the top of the modifier stack. This allows you to manage all modifiers on an object at once, which is very useful for finalizing geometry or debugging.
Add Mesh: Extra Objects​
Category: Modeling | Installation: Edit > Preferences > Add-ons > Search "Extra Objects"
Adds many new primitives to the Shift+A > Mesh menu, including gears, diamonds, pipes, and math functions. Most importantly, it adds the Single Vert object, which is useful for point-to-point modeling and retopology.
Add Curve: Extra Objects​
Category: Modeling | Installation: Edit > Preferences > Add-ons > Search "Extra Objects"
Adds parametric curve shapes like spirals, helixes, torus knots, and curve profiles to the Shift+A > Curve menu.
Images as Planes​
Category: Import-Export | Installation: Edit > Preferences > Add-ons > Search "Images as Planes"
Simplifies importing images by automatically creating a plane with the correct aspect ratio and material setup. Accessible via File > Import > Images as Planes.
How to Install Addons​
Drag & Drop
Drag the .zip or .py file directly into the Blender window.
Extensions Platform Edit > Preferences > Get Extensions. Search for the addon and click Install.
Install from Disk Edit > Preferences > Get Extensions. Click the top-right arrow, select Install from Disk, and choose the file.
Most Blender addons are developed by the community. This means development can sometimes stall, and addons may not be updated to work with the latest version of Blender.
If an essential addon is not working in your current version, we recommend using Blender Launcher. This tool allows you to easily install and manage multiple versions of Blender side-by-side, so you can use the specific version required for a particular tool.
