The decision, in plain words
For a solo builder at 50GB bandwidth/month and a $50.00/mo budget for the hosting platform slot, Fly.io leads at 80% fit and $9.08/mo. The two rules doing the work: budget fit (~$9.08/mo is 18% of your $50/mo budget); ecosystem maturity (established — our estimate from ecosystem age, docs and hiring pool).
Railway runs close (76% fit, $12.50/mo). It takes the lead if ~$12.5/mo is 25% of your $50/mo budget matters more to you than the current weights assume.
Honest weak spot of the pick: no free tier — paying from day one.
