How we count
Koyeb is cheaper on 4 of the 4 shapes both sell, Fly.io on 0. Fly.io gives you a machine of your own, started and stopped in a second; Koyeb takes your code or an image and runs a container of it for you. The two catalogues overlap without matching.
A shape is a runtime with the same stated memory at both, smallest first, or a subscription at the same step of both ladders. A seat and a gigabyte are never put in the same row.
Where one side of a row costs nothing, neither is marked as the cheaper: free is a limit rather than a price. What each platform meters on top is listed beside the prices and never folded into them, and a rate that is not published is not a rate of zero.
Frequently asked

- On the 4 shapes both sell, Fly.io is cheaper on 0, Koyeb on 4. Prices exclude tax and were read on 1 Nov 2026.
- What is the difference between Fly.io and Koyeb?
- Fly.io: You get a machine rather than a container: it boots in about a second, it stops when you stop it, and it costs nothing while it is stopped. That makes the monthly figure a ceiling rather than a bill, and it is the number this index carries, because a machine you leave running is what a month of hosting costs. Koyeb: You push a repository or an image and the platform builds it, runs it and keeps it running. There is no operating system to look after and no root, which is the point: the container is replaced rather than repaired. What you size is memory and a share of a processor.
