Sylve aims to be a lightweight, open-source virtualization platform for FreeBSD, leveraging Bhyve for VMs and Jails for containerization, with deep ZFS integration. It seeks to provide a streamlined, Proxmox-like experience tailored for FreeBSD environments. Its backend is written in Go and the frontend is written in Svelte (with Kit).

We’re proud to be supported by:

• FreeBSD Foundation
• Alchemilla

You can also support the project by sponsoring us on GitHub.

These only apply to the development version of Sylve, the production version will be a single binary.

• Go >= 1.24
• Node.js >= v20.18.2
• NPM >= v10.9.2

Sylve is designed to run on FreeBSD 14.3 or later, and it is recommended to use the latest version of FreeBSD for the best experience.

Running Sylve is pretty easy, but sylve depends on some packages that you can install using pkg or the corresponding port to that package. Here's a list of what you'd need:

We also need to enable some services in order to run Sylve, you can drop these into /etc/rc.conf if you don't have it already:

sysrc ntpd_enable="YES" # Optional
sysrc ntpd_sync_on_start="YES" # Optional
sysrc zfs_enable="YES"
sysrc linux_enable="YES" # Optional
sysrc libvirtd_enable="YES"
sysrc dnsmasq_enable="YES"
sysrc rpcbind_enable="YES"
sysrc nfs_server_enable="YES"
sysrc mountd_enable="YES"
sysrc samba_server_enable="YES"

Enabling rctl is required. Do this by adding the following line to /boot/loader.conf:

kern.racct.enable=1

Install required packages.

pkg install git node20 npm-node20 go tmux libvirt bhyve-firmware smartmontools tmux samba419 jansson swtpm 

Clone the repo and build Sylve.

git clone https://github.com/AlchemillaHQ/Sylve.git
cd Sylve
make

cd bin/
cp -rf ../config.example.json config.json # Edit the config.json file to your liking
./sylve
