Fly.io ranks #8 in Deployment & Hosting Platforms AI search.

Fly.io is a developer-focused global public cloud platform that enables teams to deploy full-stack applications and databases close to end users across 35+ regions. Its core primitive is Fly Machines—hardware-virtualized KVM/Firecracker microVMs that launch in milliseconds and run on Fly-owned bare-metal hardware, offering VM-grade isolation with serverless-like startup speeds. A Rust-based Anycast proxy routes traffic to the nearest healthy instance while WireGuard provides encrypted private networking. Fly supports Docker images and auto-generates containers for major frameworks including Rails, Phoenix, Django, Laravel, and Next.js. The platform offers Managed Postgres, Tigris object storage, Upstash Redis, and GPU compute. Founded in 2017 and headquartered in Chicago, Fly.io has raised ~$115M and is backed by Andreessen Horowitz, EQT Ventures, and Intel Capital.
