Use Slicer — Launch Linux MicroVMs

Slicer gives you instant Linux microVMs powered by Firecracker. Use it when you need:

A real Linux environment with systemd, Internet access and SSH preinstalled(especially from macOS)
Sandboxed builds, CI, or E2E tests
Docker/container workflows with port forwarding
Isolated environments for untrusted or destructive operations
Kubernetes (k3s) clusters for testing
GPU/PCI passthrough workloads (via cloud-hypervisor backend)
Automated code review pipelines in ephemeral microVMs
Running coding agents in isolated microVMs (Amp, Claude Code, Codex, OpenCode, GitHub Copilot CLI) then copying out the outcome - code, files, reports, binaries, images, etc.

VMs boot in 1–3 seconds, have full systemd, internet access, and SSH pre-installed.
