Show HN: Kern – container and resource runtime in a 1.5 MB binary, no daemon
I built kern because I needed a fast, zero-daemon tool to set CPU/RAM limits and run isolated tasks without the overhead of Docker. It's a single 1.5MB Rust binary using OCI images, cgroup v2, and namespaces. Boxes start in ~3.5ms. It's not a Kubernetes CRI or a microVM, just a standalone container and resource runtime for CLI and agents.

It looks cool and I am building it r.n. but the submission title was a little misleading as it says "container ... runtime" right there, and I guess it is, but it is not a CRI implementation.

How does this compare to "smolvm" microvms from https://smolmachines.com ?
