On the Team plan you have 20 users included (which equates to $5 per users per month). Every additional user will cost $4 per month. Note that Glide only takes into account active users, that is a user that signs in at least once during the billing cycle.
Also note that a user is a person who signs in to the app with an email address. A visitor is someone who visits the app without signing in with an email, and visitors are uncapped on all plans.
I understand what you mean, Team feels like a upgrade from Maker because of the price points. But this is not the case. Team is for a business use case, Maker is for a consumer use case. The use cases are so different that it’s difficult to compare the two plans.
The Team plan is for businesses, and Glide is ideal for teams and companies that have 20 to 100 employees, perhaps up to 500. So indeed on the Team+ plans, there is no need to have a large number of users (not thousands or millions that is, up to a few hundred is plenty large).
For unlimited users, the Maker plan is what you need.
