This is a question I get often and actually don’t have the best answer to. It is similar in many ways to things like Django (define models, get stuff like admin for free) and ActiveRecord from Rails (easy to do your data operations through a resource).
In the early days of Ash, I spent almost 2 years working on a no-code platform. Ultimately that venture did not work out, and I learned that, IMO, "no code is not the answer. However, I’ve synthesized a lot of what I learned in that process into Ash. In that way, Ash bears some resemblance to no-code platforms. You could think of it as the highest-code low-code framework that exists.
