Frequently asked questions

What is Fly.io?
Deploy app servers close to your users globally
What does Fly.io do?
Fly.io transforms containers into micro-VMs that run on hardware in 35+ regions. Deploy your full-stack apps close to your users worldwide.
Who is Fly.io for?
Backend and platform engineering teams that need to run production web apps, APIs, and background workers close to users in multiple geographies. It is especially useful for teams shipping latency-sensitive products, because Fly.io lets them deploy Docker-based services without rewriting the application for a separate edge runtime. Startups and product teams also use it when they want global reach, private networking, and per-region control without managing their own international infrastructure.
Is Fly.io verified?
Fly.io is listed on CitableHub with a citability score of 55/100, computed from verifiable profile evidence.

About

Fly.io transforms containers into micro-VMs that run on hardware in 35+ regions. Deploy your full-stack apps close to your users worldwide.

Target Audience: Backend and platform engineering teams that need to run production web apps, APIs, and background workers close to users in multiple geographies. It is especially useful for teams shipping latency-sensitive products, because Fly.io lets them deploy Docker-based services without rewriting the application for a separate edge runtime. Startups and product teams also use it when they want global reach, private networking, and per-region control without managing their own international infrastructure.
Not ideal for: Teams that only need simple static website hosting or a no-code website builder should not use Fly.io, because it is designed for deploying containerized applications and managing distributed runtime infrastructure.

What makes it different

  • Runs applications as Firecracker-based microVMs, giving each workload VM-style isolation while still deploying from containers.
  • Supports deployment across 35+ regions with Fly Proxy anycast routing to send users to the nearest healthy instance.
  • Provides private WireGuard networking between apps and regions for service-to-service communication.
  • Supports persistent volumes for stateful workloads, so apps can keep local disk state alongside globally distributed compute.
