This is why we built chrome-stats.com - to give users and developers more insights into what is going on in Chrome Web Store. All data are updated daily (there might be one day delay between when the data shows up in Chrome Web Store vs. here). Here are some interesting facts that we have found:

1. Extensions, themes, and apps

There are 186,449 items in Chrome Web Store. Out of those, 139,748 (74.95%) are extensions , 28,934 (15.52%) are theme , 17,767 (9.53%) are applications. What are Chrome applications? They are like a regular websites with extra capabilities. Chrome applications are deprecated, though many existing ones can still be found and installed from the Web Store.

Similar stats can be seen at the author level (looking at the sum of all active users across all extensions owned by a publisher). 83.03% of all authors have less than 1000 active users. Only 263 authors have 1M+ cumulative active users.
