What category size and maintenance mean for choosing
The category has many plugins, but relatively few reach the higher active-install threshold; most have recent update activity.
There are 517 plugins in the category, 13 with at least 10,000 active installs, and none with 100,000 or more. That limited concentration at higher install levels means the most-installed options still fall below the 100,000 mark. Meanwhile, 77% of plugins were updated within the past 12 months, a broad sign of recent maintenance across the category.
