Fly.io charges per-second for running machines plus storage. Key levers: auto-stop idle machines, suspend instead of stop, right-size VMs, and clean up unused volumes.
| Resource | Free Tier | Cost |
|---|---|---|
| shared-cpu-1x (256mb) | 3 VMs free | ~$1.94/month each |
| shared-cpu-1x (512mb) | included | ~$3.88/month |
| shared-cpu-2x (1gb) | - | ~$11.62/month |
| Volumes | 3GB free | $0.15/GB/month |
| Bandwidth | 100GB free | $0.02/GB after |
| IPv4 | 1 free per org | $2/month each |
# fly.toml — stop machines when no traffic

auto_stop_machines = "stop" # Full stop (cheapest, ~5s cold start)
auto_start_machines = true
min_machines_running = 0 # Allow all machines to stop
# Use min_machines_running = 1 only for production apps
# Suspend keeps memory state — resumes in ~100ms but costs ~$0.50/month

auto_stop_machines = "suspend"
# List all apps and their machine counts

# Destroy unused apps

# List and delete orphaned volumes
fly volumes list -a my-app
fly volumes destroy vol_xxx
# Check memory usage to see if oversized
fly ssh console -a my-app -C "cat /proc/meminfo | head -3"
# Downgrade if using <50% of allocated memory
fly scale vm shared-cpu-1x --memory 256 -a my-app
# Check current month's usage
fly billing # Shows org-level billing
# Estimate per-app cost
fly scale show -a my-app # See VM count and size
