Ah, this is a nice idea, and it seems well executed, so nice work!
My first reaction was "well, of course stuff like 'configuring servers' and 'CI/CD' (from the philosophy page [0]) isn't just overhead, it's beneficial and indeed necessary complexity once you need certain guarantees from your software's behavior and the way you deploy it"
But, I'm sure you're already well aware! That probably isn't the point of what you've built, it seems like it has a lot more value in lowering the barrier to entry for writing backend code (perhaps for people who otherwise wouldn't have bothered), which can still be a lot of friction even using something like Heroku, for instance.
