Any particular reason why you want this with microVMs? Security (kernel separation) or snapshot support perhaps?

A friend already made something similar for personal use, but using docker containers hardened with gVisor.

+1 for this. Looking for something like exe.dev. self hosted . I tried using ionos cloud VPS , 4gig one could not handle even 3 basic web servers.

I am working on https://github.com/isola-run/isola which uses gVisor (not firecracker) on k8s (or something like kind, locally). Includes snapshotting, network controls and everything. Hope you could find this useful

I'm using https://coder.com for all my development containers. I've got mine hooked up to a k8s cluster, but anything that you can provision with Terraform can be used (e.g. docker containers).

firecraker is optimized for lambda. ie: fire and forget. not so much live systems that maintain long running state. also, I dont' think you can run it on top of a hypervisor.
