I am new to Fly.io.I want to know about your free plan and its limitations. As far as I understand, the shared-cpu-1x 256mb VMs you provide are sufficient for my small apps development work. Is it possible to spend money from my card without my knowledge? If so, how do I manage it?
Maybe this conversation will be helpful
And if bandwidth ever goes up by a million because of a mistake do let us know, we don’t want to bill you for a mistake.

I have a Legacy Hobby plan, which says it has 3GB free. Can I allocate the 3GB to the Postgres instance? My database is 1.3GB? or it is 1GB / vm instance ?
This is implemented as a $0.50/month credit, earmarked for volumes in general, which automatically offsets whatever charges your actual provisioning pattern chalked up.
You can see it getting consumed “live”†in the dashboard, under Billing > Active Credits > Show breakdown.
For a production-quality Fly Postgres cluster holding 1.3GB of data, you would need ≥6GB of volume space provisioned in total (2GB per node × 3 nodes). That would be $0.90/month, of which $0.50 would be paid with the credit—leaving $0.40 due on the monthly invoice.
Hope this helps!
