Frequently asked
Fly.io alternatives FAQ
- Is Fly.io free?
- Fly.io lets you start for free and bills by the second for compute, so small deployments can cost very little. The cheapest shared-cpu-1x machine with 256MB of RAM is USD 0.0027 per hour or about USD 1.94 per month, and storage is billed on provisioned capacity at USD 0.15 per GB per month. There is no traditional free tier with a fixed monthly allowance.
- How much does Fly.io cost?
- Machines are billed by the second while running. Shared CPU presets start at USD 1.94 per month for 256MB and go up to USD 15.55 for 2GB, while performance presets run from USD 31 per month for 2GB up to USD 496.01 for 32GB. Volumes are USD 0.15 per GB per month, egress ranges from USD 0.02 to USD 0.12 per GB by region, and Managed Postgres starts at USD 38 per month for a 1GB shared cluster.
- What is the best Fly.io alternative?
