Fly.io
Fly.io is a platform for deploying applications and databases as lightweight virtual machines (Machines) across a global network of regions, billing compute by the second it actually runs. Pricing starts around $1.94 a month for a small shared-CPU machine, with storage, bandwidth and managed Postgres priced separately.

A good fit for
- Applications needing low-latency access for a globally distributed audience
- Teams wanting granular, per-second compute billing rather than flat monthly instance pricing
- Developers comfortable with Docker-based deployment and CLI-driven workflows
- Projects needing a managed Postgres option alongside compute in the same platform
Not a good fit for
- Teams wanting a simple flat monthly price without tracking several separately billed components (compute, storage, bandwidth)
- Non-technical users wanting a fully managed, no-configuration platform
- Very predictable, low-traffic workloads where a simpler flat-rate host might be easier to budget for
Fly.io pricing
A small shared-cpu-1x (256MB) machine costs about $0.0027 an hour ($1.94 a month running continuously), while a performance-1x (2GB) machine costs about $0.0431 an hour ($31 a month). Additional RAM costs $5 per GB monthly, up to 128GB. Volumes cost $0.15 per GB a month, and Snapshots cost $0.08 per GB a month with 10GB free monthly. Managed Postgres costs $0.28 per GB a month. Bandwidth ranges from $0.02/GB (North America and Europe) to $0.12/GB (Africa and India). A dedicated IPv4 costs $2 a month; shared IPv4 and Anycast IPv6 are included.

About Fly.io
Fly.io runs applications as lightweight virtual machines called Machines, deployed close to users across a global network of regions, aimed at developers who want low-latency access for a geographically distributed audience.
Billing is granular: compute is charged by the second while a Machine actually runs, storage (Volumes and Snapshots) is billed by provisioned or stored capacity, and bandwidth (egress) is priced differently depending on the destination region.
Fly.io also offers a managed Postgres option, priced per GB, and both dedicated and shared IPv4 addresses alongside unlimited Anycast IPv6, giving developers granular control over networking costs.
