We experimented with putting some user limits on our subscription plans. But it looks like this interferes with the business model of some of our upstream customers and also interferes with how we count users across apps and Cloudron itself. To avoid all the confusion, we have simply removed user limits from all plans. Same goes for app limits - there is no limit anymore (but there is still a restriction of more than 5 instances of the same app).
In the end, we still need a way to distinguish between personal and business use. For this reason, we have now tried put some of the apps are premium apps. Premium apps is simply based on our understanding that those apps are usually run by small teams/companies. Besides, those apps also require quite some work for us to manage compared to the rest.
Current users will be grandfathered to a plan which is the equivalent of the current business plan with no change in pricing.
