Fly.io is a global application platform that lets developers deploy full‑stack apps and databases close to their users for low‑latency performance. It runs applications inside fast‑launching Firecracker microVMs that offer the speed of containers with the isolation of virtual machines, enabling long‑running processes, WebSockets, background jobs, and even GPU‑accelerated workloads without typical serverless limitations. The platform uses Anycast networking to route traffic to the nearest region automatically, with encrypted backhaul via WireGuard for secure, efficient communication. Developers can scale apps to thousands of instances or down to zero, use persistent NVMe storage through Fly Volumes, or opt for the fully managed Fly.io PostgreSQL service with high availability and automated failover. Fly.io supports most major languages and frameworks, offers a strong CLI‑based developer experience, integrates with GitHub Actions, and provides a distributed systems–friendly environment for globally deployed applications.
