Reintroducing Capsul

I know it’s an aside but I’m so impressed with the quality of this (linked) page:

The UX is exceptionally strong. It’s like you’re on a ‘real website’ — it’s quite enveloping in terms of its vibe, palette, ease of comprehension and the colour palette is so cool.

Definitely a tilt in favour of boldness with colour on web.

Just wondered if the vm provising frontend is opensourced in all or part? Not looking to clone your business, just for a provisioning framework that allows for fiddling (as opposed to say something like proxmox, which allows for provisioning via a friendly UI but can't practically be tweaked behind the scenes).
