I don't think it's much cheaper. Writing some code to do some CRUD has always been easy. Getting to a proof of concept is definitely quicker. But creating something that can be relied upon in production? That's as difficult and time consuming as it has ever been.
Yup. I've explained it as okay, some software is free as in beer and others are free as in speech. DIY software is free as in yacht.
It sounds nice, but now you have something that takes an enormous amount of time and effort to use and maintain, plus you need to have someone with the skills to run it.
