I have the $16 plan. Does anyone know how many people can Bubble handle on 1 site before crashing or do I need to upgrade?
It really depends on the complexity of your app. Some Bubblers with simple apps do fine on the $16 plan, others require a Professional or higher.
I really wish i had the answer to that as well. The honest answer is that nobody knows. Of course, it depends on the page size, the amount of workflows and other stuff as well.
There was a thread from a few months ago, and we came to an estimation of about 10-20 concurrent users for a simple CRUD app with some workflows on the back-end and some on the client side.
