The point that foxbee was trying stress is that Budibase is not for building SaaS products.

There is absolutely no reason why you could not give login's out to your customer - i.e. a customer portal.

It's just difficult to draw this distinction with simple terms, so sometimes we say "Internal" to try and separate from "SaaS Product". Naming is hard - we've been using the term "Business App" more often now.
