Mapbox Premium plans now include maps behind a paywall for up to 1,000 seats. It’s just included with every Premium account. Until recently, applications with maps behind a paywall required custom Enterprise pricing. Now it is much easier to get up and running with applications behind paywalls: just select the Premium plan, swipe a credit card, and go.
We don’t consider paid mobile applications on iOS or Android to be behind a paywall. I just updated our help docs on all the details. It’s pretty straightforward: a seat is equivalent to a user account on your web platform, or a single-user license in your desktop software application. If you have any questions, hit me up personally by asking for Ali when you e-mail help@mapbox.com.
