Motivated by recent drama regarding Fly's throttling changes (https://community.fly.io/t/predictable-processor-performance/22259), I started thinking about building an alternative to Fly.io's performance machines (no overprovisioning), which would be 5x cheaper.
https://fly.io/docs/about/pricing/
Instead of paying $0.1722/hour for a 4vcpu machine/container, you'd pay $0.03444/hour.
It'd run on Hetzner infrastructure, using Firecracker microVMs.
It'd have a minimal interface. You'd build and push a Docker image with a CLI. After that, you'd start containers / communicate with them / destroy them over REST.
Any interest?
