The hosting choice is the easy half — your bill at scale is the hard one

The hard half is your bandwidth bill at 1M page views, your egress cost when you migrate, and the platform-lock that comes with every bundled service. The 30-min call is where you describe your traffic shape and your stack; I tell you whether Railway or Fly.io (or something else) is your fit.
