Install and update third-party addons to FreeCAD, including Workbenches, Macros, Preference Packs, and more. FreeCAD ships with a point-in-time snapshot of this Addon: by the time you install FreeCAD it is possible that version of the Addon Manager is no longer the most recent version. Install this addon to update the internal Addon Manager to the latest version (and to allow future self-updating).
Note that there are multiple available branches of this addon. Most users should use Main, but Development is also available and may contain work-in-progress features (but may also be less stable). For users on older versions of FreeCAD built using Qt5 and/or Python 3.8, a dedicated branch is available.
The main source of addons is the git repository at https://github.com/FreeCAD/Addons. Custom addon sources can be configured in the Addon Manager preferences when running FreeCAD. These addons are primarily written by third parties and provided by repositories not under the FreeCAD authors' or maintainers' control: you use these addons at your own risk.
To submit an addon you have created see the documentation here.
For information about developing an addon in the first place, see the FreeCAD wiki.
The Addon Manager supports five different types of addons: "Workbench", "Macro", "Preference Pack", "Bundle", and "Other". This
information is provided to the Addon Manager via a file called package.xml whose format is documented on the wiki.
The Addon Manager relies on a remote cache of all addons maintained at https://addons.freecad.org, generated by a script that runs every six hours. This cache contains the complete code for all addons listed in the addon catalog. Another process runs to cache all macros from both the GitHub repository and the Wiki. All official catalog-based addons and macros are downloaded from that server.
