The decision, in plain words

For a solo builder at 500GB bandwidth/month and a $50.00/mo budget for the hosting platform slot, Fly.io leads at 76% fit and $34.24/mo. The two rules doing the work: budget fit (~$34.24/mo is 68% of your $50/mo budget); ecosystem maturity (established — our estimate from ecosystem age, docs and hiring pool).

Honest weak spot of the pick: no free tier — paying from day one.

Generated from the calculation above — every number traces to the sourced data; nothing here is written by an AI making things up.
