Computers for agents,
from sandboxes to production

Give your agent its own hardware-isolated Linux computer. Deploy what it builds without changing platforms.

Start free

Work with the agents and tools you already use

Your agent gets a Fly computer and all the plugins, SDKs and templates it loves.

See all integrations

Built for what you're shipping

Web Apps

Host the web apps you and your agents build, with Postgres and storage.

APIs

Run the APIs behind your product on VMs in 18 regions, close to your users.

Coding Agent Workspaces

Give your engineering team access to Claude Code and Codex in the cloud.

Agent Fleets

Run untrusted code, evals, and RL rollouts in parallel. Checkpoint what works, throw away the rest.

Agent Products

Get a computer for every customer’s agent. It sleeps (at zero compute cost) until you wake it on request.

Use the tech you love

Deploy apps and agents built with your favorite framework. Ship from GitHub or our CLI with fly launch. No Dockerfile? No problem: we'll generate one for most popular frameworks, including Rails, Phoenix, Django, Node, Laravel, Go, Rust, .NET and more.

“Fly.io just worked so well for our dev and build processes. We needed something robust for stateful, persistent sessions, and Fly.io was perfect.”

“Without Fly.io, we’d probably still be stuck tweaking node groups and worrying about start-up times.”

Secure by design

The answers your security review will ask for (but way more than they want to know. We can't help it, we nerd out about this stuff.)

Read the security overview
  • Hardware isolation, always

    Every computer is its own Firecracker microVM. No shared kernel, and no faster mode that skips it.

  • Credentials stay out

    Connectors broker logins and API keys at the gateway. The agent uses them without ever holding them.

  • Egress you control

    Lock any computer to an allowlist of hosts. Private networking between everything else by default.

  • Compliance, built in

    SOC 2 Type II. HIPAA with a pre-signed BAA. SSO and support SLAs for enterprise teams.

Comparing your options?

There are four things an agent's computer needs to do. Here's how every platform measures up.
