You can count the base targets in the Workspaces tab
You will see the total number of base targets per each workspace. Base targets are the ones we count towards your plan limitations. 10 for Pro Basic, 100 for Pro Advanced, and 1000 for Enterprise.
From the /targets tab
At the bottom of the page, you will see a message that tells you how many targets you have in the current workspace, for example: “Showing 1 to 10 of 54 entries”. However, you can scan as many targets belonging to a base target and they will still count as one from your total plan limit.
