(this keyboard does not appear to be QMK-based, but for the record) any keyboard that runs QMK (an open-source firmware for keyboards) will offer the same experience. web-based configurator and full linux support.

Nuphy's other keyboards, such as the Air v2 (which I own and use), are QMK based. It's just the hall effect keyboards that aren't.

I think mean to say QMK?

Configuration stored _on the device_ and not needing the software to autorun every time you reboot to get your settings back, should really be a no-brainer. There's unfortunately enough gaming keyboards and mice out there who haven't got this yet.

I'd love to see some standard HID feedback channel for interactive keyboard LED control. My previous Logitech keyboard had some fun interactions with Factorio that I miss. Things like flashing a specific letter or using the backlighting to show a progress bar.

Many mechanical keyboards use firmware works with Web Apps that use WebUSB/WebHID APIs to allow easy cross-platform configuration. It's a welcome change over dedicated desktop software for your keyboard. All the configuration is stored and behavior is managed on the keyboard itself. This doesn't get you cool things like keyboard LED interactivity, but I can live without that.

This is why WebUSB/WebBT is a good thing, you can build configuration tools that run anywhere and are easily ported offline or replicated.

"Handy" and "a good thing" are not the same thing.

USB and BT are security nightmares, and the browser is a fantastic sandbox. I'm pretty sure a lot of 0-days will come from there.

As always you have a choice between things existing at all on Linux or fretting about the security issues that so far have not materialized.

RAZR is the worst offender here
