We build the open infrastructure stack we always wanted:
real VMs with a real API, Kubernetes-native virtualization, eBPF networking, GPU scheduling and an offline-first edge.
Written in Rust and Go. Apache-2.0 at the core.

FluxVM Rust |
One control plane for Firecracker, Cloud Hypervisor, QEMU/KVM, Apple Virtualization.framework and our own hypervisor. No libvirtd, no XML: one REST API and CLI on every backend. Docs → |
Kairon Go |
Real VMs, real Kubernetes, no virt-launcher. Kubernetes declares, Kairon orchestrates, FluxVM executes. Live migration and eBPF flow logs built in. Docs → |
GuestKit Rust |
Look inside any VM disk without booting it. Zero agents, instant insight, and AI diagnostics that tell you what's broken before first boot. Docs → |
Fabric Rust |
A private cloud for Linux in one daemon: VMs, networking, storage and security. Docs → |
Velora Swift |
VMs, models and clusters on your Mac. Debian, Ubuntu and macOS guests on Apple's Virtualization.framework, a Console & Command channel over vsock, local MLX models behind an OpenAI-compatible gateway, k3s and a fleet of Macs. Site → |
Gryvia for Apple Swift · Python |
Your Macs, scheduled. A multi-tenant control plane for Apple Silicon fleets: admission against each Mac's unified-memory budget, quotas, live GPU cores, a model workbench and signed provenance. Docs → |
 Velora: VMs, models and clusters on your Mac. Download → |
 Gryvia for Apple: your Macs, scheduled. Screenshot of the simulated demo fleet. Live demo → |
Also on the Mac: Macora explains your network · Nivora shows every connection per app · FluxVM drives Virtualization.framework underneath.
sudo fluxctl create --spec examples/qemu.json # a real VM, any backend, no libvirtd
fluxctl exec <id> -- hostname # run commands over vsock, no SSH
kaironctl create demo --image ubuntu.qcow2 --cpu 2 --memory 2Gi
kaironctl migrate demo --strategy live --target-node worker-2On a Mac (Apple silicon; the Homebrew tools need macOS 14+):
brew tap zyvorai/tap
brew install zyvorai/tap/fluxvm # FluxVM on Virtualization.framework
brew services start fluxvm # the daemon, API on 127.0.0.1:7788
fluxctl run # a throwaway Debian VM and a shell
brew install --cask zyvorai/tap/macora # explain why your network is slow: app + CLIVelora is not in the tap and needs macOS 26+: grab the .pkg or .dmg from the latest release. It is ad-hoc signed, so the first time, right-click it and choose Open.

Everything here is real, working source, not a crippled trial.
|
Same codebase, plus SLAs, air-gapped rollouts and hypervisor exit programs. |
