> Sylve supports both Bhyve virtual machines and Jail-based workloads from a single UI. It also includes Samba share management and ZFS snapshot automation with periodic schedules and retention policies, so teams can run workloads and protect data from one control plane.

This is awesome! I only started toying around with Proxmox after VMware became actively hostile towards users last year or maybe a bit earlier. This is a welcome alternative in the space. It's impressive. But the reputation of FreeBSD and the inclusion of ZFS and jails from the people I trust most to build a lightweight system is pretty great and I'm excited to see how this develops over time.

Surely that's "on" FreeBSD not "by" FreeBSD?

Should be "built on"

It’s funded by the FreeBSD foundation, so “by” fits.

But it's got a separate entity providing paid support?

svelte is very new, it’s supported by the foundation not by. also the foundation is not freebsd they are two separate entities. freebsd is the developers, the foundation is a bunch of canadians supporting said developers.

Looks good! Any reason why it is not in the ports?

Sylve Dev here! The port is in review and the maintainers has told me that it'll be merged into the next quarterly slush (which is next week). And the installation script on the website will automatically switch to ports when it's available.

Looks great! Love seeing Svelte being adopted in the wild.

I've been experimenting with jails on my devserver to sandbox AI agents, going to give this a whirl.

I would've given up on this project without Svelte 5! It’s so hard to justify React after using it. Proxmox always felt sluggish, but Sylve with Svelte stays smooth even on large clusters. DX is also much better. We started on Svelte 4 but moved early to 5 for things like runes.

Jails are great if your packages are in ports, and if not, Linux jails work well too: https://sylve.io/guides/deployments/rocky-linux-jail/, Haven't hit a CLI app that doesn't run in a FreeBSD Linux jail yet!
