I don't understand why it's only for internal applications.

If the form looks good and works, I would put it as a solution for my customers.

Maybe I would not create the whole application with Budibase, but for some screens for entering data + showing tables, yes.

What reasons do you think this is not feasible?

And as a business idea, I think that the first "no code"/"low code" that removes the "only for internal apps" will get the most developers interested. (like me)
