Fly.io Hosting: Plans, Prices & Review

Fly.io is a cloud platform for deploying and running applications close to users worldwide. It uses hardware-virtualized containers called Fly Machines that launch in under a second across 18 global regions. Supports any language or framework via Docker.

Fly.io uses pure pay-as-you-go pricing with per-second billing. You pay for compute (CPU and RAM), persistent storage (volumes), and network egress. There are no fixed plans or minimum commitments. All organizations require a credit card on file.

The smallest named preset is shared-cpu-1x with 256 MB of RAM, at $1.94/month if it runs continuously (billed per second). Additional RAM is about $5 per GB per month.

Fly.io no longer offers a free tier for new customers (discontinued October 2024). New signups get a free trial with limited compute hours. Legacy customers on old Hobby/Launch/Scale plans retain their free allowances (3 shared VMs, 3 GB storage).

Fly Machines are hardware-virtualized containers that combine the security of VMs with the speed of containers. They launch in under a second and can be stopped when not in use — stopped Machines are charged only for rootfs storage at $0.15/GB/month.
