Looks like it offers a much higher level of abstraction than that.

Seems closer to Heroku/Vercel but running in your own AWS account.

So AWS Beanstalk? :)

You forgot the trigger warning :)

But jokes aside, I use Beanstalk quite a bit and it's mighty leaky, don't find it all that comparable to stuff like fly.io, although in spirit it's the same thing I suppose.
