JetKVM is much like nanoKVM but a slightly polised version. Control any computer remotely with next generation open-source KVM over IP for $69.
As far as I know, these Jets are not available for retail yet, but can be bought via their kickstarter.

I wish it was possible to connect it to VGA servers to 🙁
They’re making a KVM targeted at data centers that doesn’t support VGA?
Yeah it kind of surprised me too. HDMI and USBC is good for modern servers, but we have plenty of 15-year-old servers in production and even a lot of new servers still use VGA.
Cant you just use a dongle?
Yes, I’ll have to buy a 10/15€ cheap Chinese adapter.
Their FAQ says that they haven’t tested this with KVM switches but that it should work. PiKVM doesn’t always work well with switches, hoping this will be better. Because off-the-shelf IPKVM switches all seem rubbish, overpriced or both.
Would you need one of these per physical server, or can they connect to multiple ?
I don’t know if the JetKVM supports it, but PiKVM and BliKVM support adding a multi-port HDMI switch to it (see: docs.pikvm.org/multiport/).
It’s a bit finicky depending on the device you use (some will require custom cables).
It’s for one , but you can use a normal kvm that supports switching with the keyboard
You lost me at a touchscreen
Oh no, what a dealbreaker
Primary use case is through terminal/web interface.
Wouldn’t be surprised if the touchscreen was a similar cost to a non-touchscreen at that size and they figured “might as well”.
It’s a touchscreen for a smart watch that they reused to save money. Would have been more expensive to design a custom screen when something like this already exists
It is not just public but Foss as well. It is under the GPLv2 which is even a copyleft license.
Yup. “Public” is not a useful qualifier as it could mean decompiled or leaked.
Wow, install Tailscale or Wireguard and you’ve got a killer remote support solution.
Unless it doesn’t boot.
If the machine doesn’t boot then you can use this to access the bios and boot a recovery environment of your choice remotely using pxeboot.
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.
Backed this on Kickstarter. Seems honestly too good to be true, so I am antsy to get my hands on it.
Me and a coworker got a couple. Seems almost too good to be true. Going to try to use these on a couple of Dell machines without idracs at work.
I backed it as well. Got my shipping notice a week ago and am looking forward to playing with it.
What’s your backer number? I filled in the survey right as they sent out the link to it and still nothing despite being one of the first 500 people to back this project
Veeeery nice! I want one! (Well…maybe 2, or 3, or… 😁)
There’s the nanokvm, similar idea but cheaper. I have one and it’s okay but a bit sore, I’m hoping the jet is faster
Sorry if this question is easily answerable by reading and I’m just missing it. But I genuinely don’t really understand what this product does or what its use case is. Is it a usb stick that gives you kvm access to a computer from a remote location? Like call up someone in another building ‘hey plug the jet into tower X so I can remote in?’ In which case how is this better/worse/just different from a software solution like Barrier? Sorry if I’m being borderline deliberately obtuse but the website gives no info on the home page at all.
ELI5:
It lets you remotely control a computer.
It’s different (arguably better) than remote connection software because it is a separate device that basically just forwards your keyboard & mouse inputs. This means that you can control the remote device even if it’s powered off or not able to boot properly, and you can configure the BIOS remotely too.
You could call someone on-site to connect the KVM to a server, but KVMs, while expensive by regular person standards, are pretty cheap as enterprise hardware goes. So some organizations just keep separate. KVMs plugged into all critical hardware all the time.
Worth noting here that KVMs are potentially a quite Hugh security risk.
Their website is probably light on details because “KVM” is fairly common industry parlance. If you normally work with this stuff then just hearing those 3 letters tells you most of what you need to know.
Worth noting here that KVMs are potentially a quite Hugh security risk.
You can put them behind a VPN and they should be relatively secure. I definitely wouldn’t expose it on the web directly, however.
As for food functionality it is very comparable to software remote control of a computer. There are 3 key features that stand out:
I have a similar project called PiKVM. I can remotely turn on my computer from a full shutdown, navigate the BIOS to select an OS, and log in, after which I typically switch to a software-based Remote Desktop which is more performant. But you can’t power on a computer and navigate a BIOS with a software solution.
Like call up someone in another building ‘hey plug the jet into tower X so I can remote in?’
The whole idea is you don’t need anyone local. You leave it plugged in 24/7 so that’s it’s accessible remotely, as needed.
For me, they’re also useful because a lot of my jobs don’t allow remote software to be installed on laptops, so I use something like this to be able to remote in still.
KVM also allows access if the machine isn’t booted up, so like mounting remote recovery images, re-installing an OS, and changing BIOS settings and that kind of thing.
I love this. I have a box I’ve been wanting to move to a family members place because they have fiber and I don’t. They’re heavy users of the plex server I have on there, so they’re happy to host it, but if I ever had issues around anything boot related I’d be down until I could physically get there.
This would also be awesome for troubleshooting some RasPi stuff where I kind of want the DE every now and then but mostly let it run headless.

Remote KVM lets you access the machine as if you’re in front of it, including pre-boot / BIOS / BSoD’s / Etc (when software isn’t / can’t run) because the device (usually) connects to the computer’s USB/VGA port.
No mention of what their actual hardware platform is that I can, so must be custom. Wonder what solutions their newly opened code can run on. Doesn’t look like ESP would work.
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
What is an “actual target hardware platform”?
I don’t exactly know what you mean but here is the OS and CPU they use.
- Operating System: Linux 5.10 with Buildroot
- CPU: RockChip RV1106G3, Cortex A7 1.0GHz, H264 & H265 hardware encoder
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 mentioned 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.
What sort of open source
Gpl Fuck yeah. Thats awsome
That Kickstarter link didn’t work for me, this one does.
Looks like $69 for:
JetKVM is a fast, open-source KVM over IP solution for managing any computer, server, and workstations remotely. Handle boot failures, install new OSes, adjust BIOS settings or simply control the computer without needing to be physically present.
And tech specs:
- Operating System: Linux 5.10 with Buildroo
- CPU: RockChip RV1106G3, Cortex A7 1.0GHz, H264 & H265 hardware encoder
- RAM: 256 MB DDR3L
- Storage: 16 GB EMMC
- Screen: 1.69 Inch IPS, 240 × 280, capacitive touch screen
- Ports: Ethernet RJ45 (100Mbps), USB-C (USB 2.0 480Mbps), HDMI Mini, JetKVM RJ11 extension port
wow, really neat design for this price range
Yeah, a bit suspicious.
They sent out a lot of review samples to different serious tech youtubers like wendal at level1 and jeff geerling. They all came back big fans.
What do you mean by “suspicious”? What are your worries?
Honestly I’ve always found the cost of KVM equipment to be super suspicious.
You need to be able to capture HDMI/VGA at very low resolution and refresh, become a USB HID host and provide this data via VNC. It’s not like we need an Elgato 8k stream coming off the hardware.
Last time I went IP KVM shopping for a small server room the prices started at around 10 grand.
Aw neat! Thanks for sharing 😊
Is there a link to the code? I know I could probably search for it, but if you’re going post about the code being public you could at least include a link to it.
you could at least
Note: here “it would be nice if” is more polite, since the least one could have done is always
Ah my bad! Had originally added it but it got overwritte by the image url - whops! Added it now.

Well I know why it opened up today: H264 patents expired
