A single <8MB binary with a modern Web UI, CLI, and API for KVM.
No XML. No bloat. Just VMs.

Flint is a modern, self-contained KVM management tool built for developers, sysadmins, and home labs who want zero bloat and maximum efficiency. It was built in a few hours out of a sudden urge for something better.

Prerequisites: A Linux host with libvirt and qemu-kvm installed.

curl -fsSL https://raw.githubusercontent.com/ccheshirecat/flint/main/install.sh | sh

Auto-detects OS/arch, installs to /usr/local/bin, and you're ready in seconds.

• 🖥️ Modern UI — A beautiful, responsive Next.js + Tailwind interface, fully embedded.
• ⚡ Single Binary — No containers, no XML hell. A sub-8MB binary is all you need.
• 🛠️ Powerful CLI & API — Automate everything. If you can do it in the UI, you can do it from the command line or API.
• 📦 Frictionless Provisioning — Native Cloud-Init support and a simple, snapshot-based template system.
• 💪 Non-Intrusive — Flint is a tool that serves you. It's not a platform that locks you in.
