Sylve is a lightweight, open-source virtualization platform for FreeBSD. It combines Bhyve virtual machines, FreeBSD Jails, and ZFS storage into a modern web interface designed to deliver a streamlined, Proxmox-like experience tailored for FreeBSD environments.

The backend is written in Go, while the frontend is built with SvelteKit.
