Show HN: Katakate – Dozens of VMs per node for safe code exec

I've built this to make it easy to host your own infra for lightweight VMs at large scale.

Intended for exec of AI-generated code, for CICD runners, or for off-chain AI DApps. Mainly to avoid Docker-in-Docker dangers and mess.

Super easy to use with CLI / Python SDK, friendly to AI engs who usually don't like to mess with VM orchestration and networking too much.

Defense-in-depth philosophy.

Would love to get feedback (and contributors: clear & exciting roadmap!), thx

I would really like to see a good local sandboxing solution in this space, something that is truly local-first. This is especially important since many coding models / agentic builders will eventually become lightweight enough to run them on-device instead of having to buy tokens and share user data with big LLM cloud providers.

What about this: https://github.com/apple/container

Very cool one. That's dedicated to Apple ARM which I don't currently support so the two are complimentary. Apple containers shares some primitives with Kata. I'll investigate if it's possible to use Apple containers as a VMM inside Kata, or creating an Apple Containers runtime class in Kubernetes. If either is possible, we could then potentially use Apple containers as a backend in Katakate. I need more time to study that.
