Just wondering how many teams there are this season/how I would check the number. Thanks
Looking at Robot Events and zooming all the way out
9,983 VRC teams
139 VEXU teams
6 VAIC teams
10,107 IQ teams
Looking at the team map will get you the number of registered teams; if what you want is “active teams” (i.e., teams that have competed at least once this season) you can get that from the API.
