About Fly.io
Summary
Fly.io builds a cloud platform that runs application servers and databases close to end users across global regions. Developers deploy Docker-based apps via a CLI and get hardware-isolated VMs that boot in under a second and scale automatically. The platform also provides persistent Linux environments for AI agents, replacing generic sandboxes with stateful computers that checkpoint and resume across agent sessions.
Business model
Pay for compute consumed, with costs dropping to zero when instances are idle
Go-to-market
Developers and AI agent teams sign up and deploy self-serve, starting with a free tier and scaling through usage-based pricing
From the Y Combinator listing
Run full stack apps close to your users.
We run app servers and databases close to end users. Developers deploy their apps to Fly.io (it's about the simplest place to deploy a Docker Image) and use our CLI to launch instances in regions that are most important for their application.
