Continue to About ↓- What it does
- Fly.io is a developer-focused public cloud where you deploy containerized apps and AI agent code onto fast-booting, hardware-isolated Linux microVMs called Fly Machines, with optional agent sandboxes (Sprites) and a managed Postgres service.
More detail
- Billing is pay-as-you-go by the second or hour for compute, plus provisioned storage and egress.
- Best for
- Developers and teams shipping containerized web apps, APIs, or AI agents who want Dockerfile-to-deploy workflows, global regions, and isolated sandboxes for untrusted or agent-generated code.
- Pricing
- Pay-as-you-go with no platform fee
More detail
- compute bills per second while a Machine runs (e.g. shared-cpu-1x 256MB at $0.0030/hr or $2.19/mo
- performance-1x 2GB at $0.0458/hr or $33.00/mo), with extra RAM at $6.00/GB/month.
- A stopped Machine bills $0.15/GB/month of rootfs.
- Sprites bill $0.0385/CPU-hour and
- Main limitation
- Buyers who want fully managed everything with no infrastructure configuration, or who need the lowest possible cost for mostly idle workloads, since stopped Machines still bill for rootfs and Volumes bill on provisioned capacity.

About
- Fly.io is a developer-focused public cloud where you deploy containerized apps and AI agent code onto fast-booting, hardware-isolated Linux microVMs called Fly Machines, with optional agent sandboxes (Sprites) and a managed Postgres service.
- Billing is pay-as-you-go by the second or hour for compute, plus provisioned storage and egress.
What it helps with
- Giving AI agents their own isolated Linux computer and then deploying what they build without switching platforms
- Running untrusted code, evals and parallel agent fleets safely
- Deploying containerized web apps and APIs with zero-downtime, blue-green rollouts
- Avoiding shared-kernel risk through per-tenant Firecracker microVMs
- Keeping credentials out of agent environments via brokered Connectors
- Distributing requests to the closest healthy instance across regions
Capabilities
A practical view of what is available and where limitations apply.
| Offering | Available | Detail |
|---|---|---|
| Fly Machines | Yes | Fast-booting, hardware-virtualized microVMs for production apps and APIs in 18 regions. |
| Agent sandboxes (Sprites) | Yes | Hardware-isolated sandboxes that stay on and scale to zero when idle, metered per hour of active use. |
| Managed Postgres | Yes | Plans from $38/mo with high availability, automated backups, failover and connection pooling. |
| Container/Docker deployment | Yes | Builds your Dockerfile into an image and boots it as a Fly Machine; supports blue-green deploys. |
| Private networking by default | Yes | Every workload sits on a private network; WireGuard encryption covers traffic on the network. |
| Egress allowlists | Yes | Computers can be locked to an allowlist of hosts. |
| Credentials brokering (Connectors) | Yes | Connectors broker logins and API keys at the gateway so the agent never holds them. |
| Autostop/autostart for idle containers | Yes | Idle Machines stop and restart on the next request; stopped Machines are not billed for CPU or RAM. |
| SOC 2 Type II and HIPAA BAA | Yes | SOC 2 Type II certified; HIPAA available with a pre-signed BAA. |
| Free tier | Limited | Starts with $1 free and no credit card required; this is a trial credit, not a standing free tier. |
