I really like exe.dev's pricing model where I pay a fixed monthly fee for compute and then can split it up into as many VMs as I want. I use exe.dev to run little vibe-coded apps and it's nice to just leave them running without a spend meter ticking up.

We're thinking about switching to this pricing model for our own startup[1] (we run sandboxed coding agents for dev teams). We run on Daytona right now for sandboxes. Sometimes I spin up a sandboxed agent to make changes to an app, and then I leave it running so my teammate can poke around and test the running app in the VM, but each second it's running we (and our users) incur costs.

We can either build a bunch of complicated tech to hibernate running sandboxes (there's a lot of tricky edge cases for detecting when a sandbox is active vs. should be hibernated) or we can just provision fixed blocks of compute. I think I prefer the latter.
