Is Bubble classified as Serverless

I read this article
Does Bubble fall into this category?
Thanks, Mark.

Bubble is a “Platform as a Service” but IMHO does not entirely fall under “serverless” because it does not scale independently based upon activity. You still need to add units and/or upgrade your plan based on volume.

But that is pretty picky, and I don’t think many would argue that it isn’t really serverless.

Hi Nigel
I appreciate your feedback and your point is well made because serverless = no cost for no use, which is not the case with Bubble.
Thanks, Mark.
