Fly.io is a cloud compute platform targeting developers who want to ship quickly without infrastructure complexity. It offers hardware-virtualized containers (Fly Machines) that launch instantly and scale on demand, plus isolated sandboxes (Sprites) for safely running AI-generated or untrusted code. Key features include fast NVMe local storage, global durable object storage, built-in private networking with end-to-end encryption, 18 global deployment regions for sub-100ms response times, and support for popular frameworks like Rails, Phoenix, Django, Laravel, and .NET without requiring a Dockerfile. The platform is SOC2 Type 2 attested, built on a memory-safe Rust and Go stack, and positions itself as suitable for running AI agents at scale.
