Side by side
Figures come from GL.iNet and JetKVM pages read on 30 October 2026. This publication has not tested either device. JetKVM's product page says pricing varies by region and points to resellers instead of listing a price, so confirm the total at checkout. [1][6]

Network: Wi-Fi versus PoE
This is the most practical difference. Comet Pro joins 2.4 GHz or 5 GHz Wi-Fi from its touchscreen, or uses Ethernet. That suits a desk or closet with no cable run. JetKVM, the full-size model, uses Ethernet, listed at up to 100 Mbps. The PoE variant can take its power from the same cable. The home page lists Wi-Fi only for the smaller JetKVM Mini. [2][5][7]
Ethernet speed matters for one task in particular: moving large disk images. On 100 Mbps, a 4 GB image takes at least about 5 to 6 minutes in perfect conditions, before protocol overhead. That is fine for an occasional reinstall but worth knowing if you swap images often. [6]
Video and display quirks
JetKVM's README is the only page here with a latency number: 1080p at 60 fps with 30 to 60 ms using H.264. Its video docs add an H.265 option on the full-size JetKVM, EDID presets up to 1920x1200, and custom EDID on the full-size model only. It warns that a wrong EDID can leave the computer with no picture. Its Low quality setting is aimed at slow or metered links such as a phone hotspot. [8][9]
Comet Pro's console offers quality levels from Low to Lossless, WebRTC or Direct transfer, and a Lowest Latency or Smooth Display mode. It also has an HDMI output, so a local monitor keeps working while the KVM captures the signal. Whichever you pick, the larger risk is a computer that sends its BIOS screen to a different output. Test that before you rely on either. [2][3]
Virtual media: upload paths differ
Both mount ISO images that the computer can boot. JetKVM offers CD/DVD mode for ISOs and Disk mode for IMG files, and suggests trying the other mode if the computer will not boot. It mounts one image at a time. Uploads to JetKVM storage work only on the local network. From outside, the option is a URL mount streamed from a web server that supports range requests. [10]
Comet Pro accepts ISO uploads in its Virtual Media panel and also offers a read-write shared drive named GLKVM for moving files both ways. GL.iNet's pages do not state an upload limit or speed. [3]
Remote access, accounts and open source
JetKVM Cloud is off by default. When enabled, it uses Google sign-in at app.jetkvm.com and accepts only the account that adopted the device. Browser and device connect directly over WebRTC, encrypted with DTLS and SRTP. When a firewall or carrier-grade NAT blocks a direct path, the session is relayed through Cloudflare TURN servers, which JetKVM says cannot read the traffic. The cloud code is open source and can be self-hosted if you choose a custom provider before adopting the device. The local password is optional, but JetKVM recommends one. Without it, anyone on the network who knows the IP can control the computer. [11][12]
Comet Pro sets an admin password at first access and adds 2FA and custom TLS certificates in the console. Its cloud is optional, with a free Standard plan and a paid Advanced plan. GL.iNet's pages we read do not describe the firmware licence. [2][3][14]
| Question | Comet Pro | JetKVM |
|---|---|---|
| Local password | Required at first access [2] | Optional, recommended; lockout after 5 wrong tries [12] |
| Two-factor | Yes, in console settings [3] | Not described for the local password in pages read |
| Vendor cloud sign-in | GL.iNet account plus KVM password [2] | Google account [11] |
| Self-host the cloud | Not covered in pages read | Yes, open-source cloud API [11] |
| Tailscale | App in Apps Center [2] | Built into Mini; script on JetKVM [5] |
Power control
JetKVM's ATX extension sits between the motherboard's front-panel header and the case cables, so the case buttons still work. A short press acts like tapping the button and a 3-second hold forces the PC off. Its docs say it works only on the full-size JetKVM for now. A separate DC extension switches devices powered by a barrel plug. [13][5]
Comet Pro relies on Wake-on-LAN or GL.iNet's ATX board or Fingerbot, both sold separately. Price either accessory into the total before comparing the two devices. [3][4]
Who fits each
| If you... | Lean toward | Reason |
|---|---|---|
| Have no Ethernet near the computer | Comet Pro | Documented Wi-Fi; JetKVM Wi-Fi is listed for Mini only [2][5] |
| Want a PoE switch to power the KVM | JetKVM PoE | Powered over Ethernet or USB-C [7] |
| Need to inspect or modify the firmware | JetKVM | GPL-2.0 source on GitHub [8] |
| Want 2FA on the device and a local monitor pass-through | Comet Pro | Console 2FA and HD OUT [2][3] |
| Upload big images often from outside the home | Neither by default | JetKVM needs a URL mount; both depend on link speed |
| Already solve issues with remote desktop | Skip both | A KVM adds value only for pre-OS failures |
Questions before you decide
Is JetKVM open source?
Its GitHub repository lists a GPL-2.0 license. JetKVM's home page says the firmware, web interface and cloud are on GitHub, and its cloud docs say you can point the device at your own cloud API before adopting it.
Which has lower latency?
Neither claim can be compared directly from these pages. JetKVM's README states 1080p at 60 fps with 30 to 60 ms latency using H.264. GL.iNet's Comet Pro docs list latency modes, including a Direct transfer described as lowest latency, but the docs we read give no millisecond figure.
Can I upload an ISO to JetKVM from outside my home?
Not to its storage. JetKVM's mount-drive docs say uploads to JetKVM storage only work on the local network. Remotely, you can mount from a URL instead, which depends on the server supporting range requests and on JetKVM's internet speed.
