Overview

What Fly.io does

Fly.io is a platform that allows you to run full-stack applications globally. It enables you to run application code near your users, in multiple regions, without managing infrastructure.

What people use it for

Deploying containerised applications close to users across regions
Running full stack apps and databases on managed machines

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Fly.io.

Egress is priced by destination region, from $0.02 per GB in North America and Europe to $0.12 per GB for Africa and India, so the same traffic costs six times more depending on where users are
Stopped machines still bill at $0.15 per GB of root filesystem a month, so a paused service is not a free one
Volumes are billed on provisioned capacity rather than usage, at $0.15 per GB a month
Reservation discounts of 40% require paying a year up front, from $36 to $1,440
Fly Kubernetes is a separate $75 a month per cluster
Dedicated IPv4 addresses are $2 a month each

Softwr does not host reviews and shows no star rating for Fly.io, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
