Most of the major programming languages have lots of open source extensions. Many of the development frameworks also have packages. Even some of the editors and IDEs have such extensions.

These extensions are sometimes referred to as modules or libraries or packages.

Sometime they get a different name.

Module counts show the list of all the module/package/library systems and the number of items in them.

Here I tried to replicate and extend that list.
