How much is Bubble per month?

I'm curious, could you please elaborate on the monthly cost of Bubble? I've heard varying figures, and I'm trying to get a clear understanding of the financial commitment involved. Is there a standard price for Bubble subscriptions, or does it vary depending on usage or additional features? It would be helpful to know if there are any hidden costs or extra fees that might not be immediately apparent. Could you please provide a breakdown of the costs associated with Bubble, so I can make an informed decision?
