## About Fly.io

### At a glance

- **Vendor:** Fly.io Inc.

- **Website:** fly.io ↗

- **License:** Proprietary

- **First release:** 2020-01-01

A platform built to run applications close to users everywhere turns out to have a customer base concentrated in one country, and the distance between those two facts is the interesting part.

Fly.io takes a container, converts it into a lightweight virtual machine on bare metal and runs copies of it in several regions, routing each request to the nearest one. Launched in 2020 by Fly.io Inc. and sold as a Proprietary service, the platform targets developers who want an application deployed in minutes with the latency profile of something deployed deliberately. Full stack applications, APIs and databases all sit on it, and the deployment experience resembles a command line rather than a hosting control panel.

As of October 2026 we detect 54,248 sites running on the platform, 51,010 of them on domains registered in United States, with the suffix mix weighted to .com. Registration country and serving geography are different measurements. A company incorporated in one place can serve traffic from a dozen regions, which is precisely what the product exists to do, so the concentration describes where these companies were founded and where they buy, not where their users sit.

Age is the second thing the data carries. A platform that appeared in 2020 has a customer base with no legacy in it. Sites arriving here were built recently, by teams comfortable with containers, and they tend to be products rather than brochures. For anyone selling developer tooling, observability, managed databases or security scanning, that profile is the whole reason to want the list, because a technology signal of this kind identifies a company stage as reliably as it identifies a stack.

A lookup on one domain confirms where a single site runs. The list answers what a stage focused buyer actually asks. How large the population of young product companies on this class of platform is. What they run alongside it. Which markets they register in beyond United States. How the set shifts as teams grow into their own infrastructure or move to a competitor.

Detection depends on the platform announcing itself through response headers, hostnames and routing behaviour. A custom domain placed behind a separate content delivery network can conceal all three, so the figure is a floor rather than a total. Release columns do not apply to a deployment platform, which is why none appears beside Fly.io, and the count reflects public web endpoints rather than internal services, so applications with no browser facing surface are absent by construction.
