See also Sprites (https://news.ycombinator.com/item?id=46557825) which I've been using and really enjoying. There are some key architecture differences between the two, but very similar surface area. It'll be interesting to see if ephemeral + snapshots can be as convenient as stateful with cloning/forking (which hasn't actually dropped yet, although the fly team say it's coming).

Will give these a try. These are exciting times, it's never been a better time to build side projects :)

Yes, sprites looks great too – would certainly be interested in a comparison.

what are the key architectural differences?

Sprites aren't ephemeral. They're like deli cups: "semi-disposable". You keep them around as long as you feel like, and you don't feel bad about throwing them away.
