Launch computers for agents, code sandboxes, and your next app.
computers for agents
The platform for devs and agents who just want to ship.
Modern Compute Without the Complexity
Fly Machines are hardware-virtualized containers that launch instantly and run only when you need them. When your app is ready, deploy it to production in minutes.
Sandboxes That Feel Like a Superpower
Spin up hardware-isolated sandboxes for running untrusted or AI-generated code in complete safety. Every Sprite is a self-contained environment, ready for action in under a second. Checkpoint your entire environment, run anything, and restore if you break something. Pay only for actual CPU and memory consumption, down to the second.
Check Em Out!Storage That Keeps Up
Fast local NVMe for low-latency work, plus global, durable object storage for data that needs to stick around. Snapshot environments, persist state, and scale storage right alongside your sandboxes.
Use the Tech You Love
Host apps built with your favorite framework. Deploy 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.
Keep Your Data Close
Pick a managed database, or run your own datastore on a Machine.
Built for Agents
Our CLIs and MCP servers are built for agents to drive. Your agent can deploy, scale and debug on its own.
- Official plugins for Claude Code, Codex, Cursor, OpenCode and more
- The Sprites MCP server, for any agent that speaks MCP
Grow Without Drama
Scale from dev to production without rewriting your infrastructure. Keep the same primitives at every scale: no rearchitecting when you grow, and no platform migration when you get big. The API you start with is the API you keep.

Support that knows the stack
Our support team writes code.
When you hit a wall, you talk to someone who's been there.

“Well, I have to say this is the best support I have ever received from any company. When I sent my initial request I expected to be brushed off as is the norm for non-standard, doesn’t fit the script tech problems. To have what is essentially a step-by-step guide in my inbox first thing in the morning is amazing, I can see why the devs like fly.io.”

“It was useful to be able to speak to fly.io directly. I found [the team] to be very knowledgeable and he helped me get clarity around areas I was stuck with, plus he offered me insight in areas I didn’t even know about. Fly.io has been a great experience from the moment I signed up. Keep it up!”
