ESRI has their own ArcGIS Code Sharing on their online
Here is the link : https://codesharing.arcgis.com//
I wonder if this site will be maintanince as we move on from the old ArcMap and past version. I wonder if this will be closed and move to a new website for the ArcGIS Pro ?
With so many old ones that no longer working , obsolete , deprecated and some tools, addin, or python may work ...
I would like to know curious will there be a update or migrate some to the new website ?
Thanks !
you can limit your search to just Pro tools.
This will limp along, but many people have github sites, for example
