flint — Modern KVM Management UI A sleek, self-contained, drop-in web UI, CLI and API for KVM virtualization. flint is a single binary, fully self-contained KVM management solution designed for developers, sysadmins, and advanced home labs. Manage virtual machines efficiently without the overhead of complex platforms. Core Philosophy Single Drop-In Binary — No installers or dependencies(other than libvirt). Self contained 8.4mb binary including web UI. Run it and you’re operational. — No installers or dependencies(other than libvirt). Self contained 8.4mb binary including web UI. Run it and you’re operational. Focused, Modern UI — Built with Next.js + Tailwind CSS for a clean, responsive interface. — Built with Next.js + Tailwind CSS for a clean, responsive interface.

Non-Intrusive — flint lives on your host as a tool, never as a platform you’re locked into. Quickstart Prerequisites: Linux host with libvirt and qemu-kvm installed. For building from source: Go 1.25.0 and bun/node.js. Download Precompiled Binary (Recommended) Download the precompiled binary from releases, then run ./flint serve . Build from Source If you prefer to build from source: Install Go (if not already installed) Clone the repository git clone https://github.com/ccheshirecat/flint.git cd flint Build the web UI cd web bun install bun run build cd .. web/out/ Build the binary go build -o flint . Running Flint After installation or building: ./flint serve The web UI will be available at http://localhost:5550 . The binary includes the web interface and serves it directly. Running in background: # Using nohup nohup ./flint serve & # Or set up systemd service sudo systemctl enable flint sudo systemctl start flint Dependencies: For precompiled binary: only libvirt and qemu-kvm . For building from source: Go 1.25.0, libvirt , qemu-kvm , and bun/node.js. Precompiled Binaries Precompiled binaries (8.4mb) are available for download from the releases page. Automated CI/CD Releases GitHub Actions automates building and publishing cross-compiled binaries on tag pushes (e.g., git tag v1.0.0 && git push origin v1.0.0 ). The workflow builds the Next.js web UI with Bun, embeds it into the Go binary using go:embed, and releases ZIP archives for Linux (AMD64/ARM64), macOS (AMD64), and Windows (AMD64). Supported Platforms: Linux AMD64, ARM64 Darwin (macOS) AMD64 Windows AMD64 Binaries are dynamically linked with libvirt as the only runtime dependency and stripped (-ldflags="-s -w").
