I really appreciate you trying it out and giving your feedback, thanks! The lack of a preview and wasted credits on mistakes is something I'd like to improve in the medium term. The way it is now, content is completely separated from presentation, and I consider that a defining feature of the product. Of course, producing each document costs essentially nothing, and the lack of a preview may be very frustrating, so perhaps meeting somewhere in the middle in terms of a preview may be the way to go. Your alternative models are excellent ideas and I will consider them as part of an overhaul of the pricing model, thanks! The rendering happens in Docker on worker instances, but a pentest is something I will look to get as well. Disallowing things like including arbitrary files from the operating system in the LaTeX code is important, I agree.
