Sylve (by Alchemilla and sponsored by the FreeBSD Foundation) is an open-source project that tries to make virtualization on FreeBSD simple and user friendly. It uses Bhyve for virtual machines, Jails for containers and takes advantage of ZFS for storage. The backend is written in Go and the frontend in SvelteKit, which gives it a clean and modern look. The idea behind it is to provide something similar to Proxmox but made for FreeBSD - including clustering support which lacks in most UI stuff (yes, cbsd can it on the cli).
> At the moment there are no ready-to-use packages for Sylve. The only way to get it running is by compiling it from source. This might sound complicated at first, but it is actually straightforward once the required tools are in place.
