Can you enlighten me on the subject of Bubble? I've been hearing a lot about it lately and am curious if it's a service that requires payment to access its features. Is it possible to utilize Bubble without any financial commitment? If so, what kind of limitations or restrictions might I encounter? On the other hand, if payment is necessary, could you elaborate on the pricing models and the benefits one might gain from paying for the service? I'm eager to learn more about this intriguing platform and how it might fit into my workflow.
