Why people consider alternatives to Fly.io
Fly.io distributes applications globally at the edge. Deploy once, run everywhere-your code on servers close to users with none of the multi-region infrastructure management. Deploys are fast. The network spans the globe.
Here are the real cost and limitation gotchas that push teams to look elsewhere:
- •Bandwidth is not free and varies wildly by region: $0.02/GB in North America/Europe but $0.12/GB in Africa and India. An app serving 100GB/month to African users costs $12/month in bandwidth alone, 6x the North American rate
- •Persistent storage (Fly Volumes) at $0.15/GB-month is pricier than cloud block storage (AWS EBS: $0.08/GB). A 50GB database volume costs $7.50/month
- •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. A 100GB database with hourly snapshots: ~$7.20/month for snapshot storage
