Man, I just wish they'd work on stability. Fly.io is an amazing offering. But it's so buggy, it's almost more headache than it's worth trying to build PaaS-flavored software on it. Even the Fly docs are "buggy" since they mostly transitioned to v2 Machines but the docs are still a mix of Nomad and Machines.
There's so much power on the platform with Flycast, LiteFS and other clever ways to work with containers. If it was 90% stable I'd consider it a huge win.
