// overview

Fly.io is a platform for deploying apps using Fly Machines (hardware-virtualized containers that launch instantly and run on demand) and Sprites (isolated sandboxes). It supports private networking, global deployment across 18 regions, managed Postgres, Fly Volumes for storage, and usage-based billing. Security features include hardware isolation, WireGuard encryption, TLS, SOC 2 Type 2 certification, and ISO 27001 datacenters.

Best for: Builders and devs who want to ship fast with instant VMs, sandboxes for AI/untrusted code, or distributed systems without complexity
