JetKVM is much like nanoKVM but a slightly polised version.
What is JetKVM?
JetKVM is a high-performance, open-source KVM over IP (Keyboard, Video, Mouse) solution designed for efficient remote management of computers, servers, and workstations. Whether you’re dealing with boot failures, installing a new operating system, adjusting BIOS settings, or simply taking control of a machine from afar, JetKVM provides the tools to get it done effectively.
As far as I know, these Jets are not available for retail yet, but can be bought via their kickstarter.

Unless what doesn't boot, the KVM? Isn't the point that this should work even if the host is not working?
As long as the host posts it should work. If it's a hardware issue then it won't help though.
No, the OS that would be running Tailscale or Wireguard. If the OS doesn't boot, those remote access options don't work, which is where a KVM comes in handy, rather than having to hook up a monitor and keyboard.
Tailscale/Wireguard are installed on the KVM itself, not the server you are trying to access. It's just a Linux machine after all.
But can it run it though? Does it have enough power?
