I worked on Aquameta for a few years and I'll say that having a build running locally is a joy I've never encountered elsewhere in my career.

Every time I need a little app or something, instead of reaching for some SAAS product, I would just build a quick prototype for myself. I could make a prototype in a couple hours and over the course of a week or two I would polish it up when I had a few extra minutes. Rather than using something built for the masses, I could tweak the interface to my own taste and I owned all the data.

No. :) It is still in early stages. I use it for my projects but I end up dropping to the PostgreSQL prompt occasionally and doing things nobody but me would know how to do. Every time I do though I try to fix the source of the problem. Really need to start putting up some example projects though. I'd say it's ready for very early adopters.
