Yeah, I've recommended https://docassemble.org/ to a lot of friends in the lawyer space. They use it a lot to generate some automate template software.
By any chance, have any of your friends shared any notable shortfalls of - or annoyances with - Docassemble?
I have had one small thing with it, if you're using the realtime preview for fancy things (one friend used it for a self-managed invitation card thing for weddings), the preview does not use the fancy fonts that are loaded into your template.
It's weird because the rest of the ecosystem is very good for almost every usecase.
