Ok, so cards on the table. The goal of PrograMaker is to be useful to as many people as possible. To do this, it will remain free (as in free-of-charge) for normal users as long as it can be possible done.
But, to support further development, we will require funds. Right now there are no user tiers, but in the future some benefits will be given to paying users, such as higher resource limits. (Note that those resource limits don't exist now.)
Our goal is to make the pricing fair, and thus, will be tied to the amount of resources used (operations executed, information flowing through the platform, pages served, ...) and, as long as it's feasible, will be usage-based. This way you don't pay for what you don't use.
Meanwhile, you can support us on Patreon. Any support will help us go futher!
Lock-in (lack of)/portability
Right now, because of the unstable pricing, you might be concerned about getting locked-in a platform. To mitigate this, we maintain a tool [prmkrctl] which can help moving programs between deployment of PrograMaker, so you can copy your programs to your own deployment at any moment.
