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.

No mention of what their actual target hardware platform is, so must be custom. Wonder what solutions their newly opened code can run on. Doesn't look like ESP code.
What is an "actual target hardware platform"?
I don't exactly know what you mean but here is the OS and CPU they use.
Are you looking for the reference manual?
If you're open sourcing something built to be deployed on an embedded device as pictured, there is a target platform (ARM, Arduino...etc) or reference board. They don't mention specifically what that is, so it's a custom board based on a RockChip. You wouldn't be able to just take this and flash it to a board that doesn't expect their customizations, is the point.
Yes, it's the OS for their custom KVM board. Released open source so it can be inspected or altered by the users of their board
