>Lightsail, it'll cost you a lot more than almost anything out there,

Lightsail is pretty competitive (price wise) with other providers. Been running s B2B app on it for a few years now - nothing much, just your basic crud app running on lightsail instance + lightsail db. Nice to have a "monthly" rate on each instead of the EC2 opaque (and "surprise!") pricing.

I have only use lightsail for one project with two VPSs, but it just works like a VPS (two, because we have another for staging). Price is competitive.

Its not my favourite, but its not terrible.
