What is Fly.io?
Fly.io is a developer platform that lets you run full applications close to your users by deploying containers to a global network of regions, delivering low-latency performance without the operational complexity of managing global infrastructure yourself. Unlike platforms that only run edge functions or simple sites, Fly.io runs your actual applications — including stateful services and databases — distributed around the world, so users everywhere get fast responses. It gives developers the power of a global deployment with a workflow simple enough for small teams.
The platform takes your app, packaged as a container, and runs it in regions you choose around the globe, automatically routing users to the nearest instance for low latency. It handles the networking, scaling, and TLS, and supports running databases and stateful workloads close to users, which many edge platforms can't. This makes it possible to build genuinely global applications — fast everywhere, not just near one data center — while keeping a developer-friendly deploy experience. For latency-sensitive and globally-distributed apps, Fly.io offers more capability than typical serverless platforms while remaining far simpler than assembling global infrastructure by hand.
Fly.io is used by developers and teams building applications that need to be fast for users around the world, or that need more control than simple serverless platforms allow. The value is global performance with simplicity: it lets teams run full apps close to their users for low latency, without the enormous complexity of managing worldwide infrastructure themselves. For latency-sensitive, globally-distributed, or backend-heavy applications, this combination is genuinely valuable. As users increasingly expect fast experiences regardless of location, a platform that makes global deployment accessible is a real advantage, and Fly.io has won a following among developers who want worldwide reach without operational pain.
What is Vercel?
Vercel is the platform for frontend developers. Push to git and get instant global deploys, previews and edge functions.
