I found great advice on Twitter https://twitter.com/pauld_fgc/status/1574107791651905536 by Paul P.

API & Platform Results:

Rails: @Railway wins. Render wakeup boot extremely slow (~1m). Flyio cannot run Rails for free.

Crystal: @Render wins. 5-10s wakeup boot time. Railway & Fly keep growing memory infinitely.

Node: @flydotio + Railway both win. Very slow boot on Render.

[o_m]

These are free plans though? Not a good comparison if you are a professional looking at this.

For Crystal, I wrote the IdleGC shard https://github.com/compumike/idle-gc to combat slow memory growth. Runs garbage collection when not servicing requests. Running in production on https://totalrealreturns.com/
