Fly.io
A platform for running containers close to users, with easy global and GPU deployment.
Fly.io runs containers on hardware near your users, making low-latency global deployment straightforward. It also offers GPU machines, so model inference and the app around it can sit on one platform.
It is more infrastructure-aware than a pure push-to-deploy host, which suits teams that want control over where and how things run.
Where it fits
A fit when an AI app needs low latency across regions, or wants app hosting and GPU inference on one platform.
Where it does not fit
More configuration than the simplest deploy-and-forget platforms: a little more to learn for a basic app.
