Is Fly.io worth the price?
Fly.io abandoned fixed plans in favor of pure pay-as-you-go, which is transparent but makes cost prediction harder.
The cheapest useful VM (shared-cpu-1x, 256MB) costs $2.02/month, genuinely cheap for a persistent server with global deployment. But costs compound quickly: persistent storage ($0.15/GB-month), dedicated IPv4 ($2/month), bandwidth ($0.02/GB in NA/EU, up to $0.12/GB in Africa/India), and volume snapshots add layers of billing.
Hidden Costs & Gotchas
Bandwidth is not free and varies wildly by region
$0.02/GB in North America/Europe but $0.12/GB in Africa and India.
Persistent storage (Fly Volumes) at $0.15/GB-month is pricier than cloud block storage (AWS EBS: $0.08/GB).
Dedicated IPv4 addresses cost $2/month each. Shared IPv4 is free but means your app shares an IP with others, some compliance and email setups require dedicated IPs
Volume snapshots cost $0.08/GB-month after the first 10GB free.
Stopped machines still cost $0.15/GB of rootfs per 30 days. An app with 10 stopped machines (1GB rootfs each) costs $1.50/month even when doing nothing
This is a significant fixed cost for teams that need K8s compatibility
Cross-region data transfer ($0.006-$0.05/GB depending on regions) adds up for apps that replicate data across regions for latency optimization
SSL certificates for custom domains
single hostname $0.10/month (first 10 free), wildcard $1/month.
