Every shape both sell, at each one's price

- 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.
