A small open-source macOS app from Trade Republic that spins up a fresh, ephemeral VM from a template, runs whatever script you point at it, and tears the whole thing down on completion. It was built as a self-hosted CI runner for iOS apps, but it's quietly useful any time you want a clean Mac for ten minutes without polluting your real one — testing an installer, opening a sketchy DMG, profiling a build from scratch.
