QMK and VIA Firmware

Flashing microcontrollers and programming layers.

Core Analysis

Why is QMK considered the standard over proprietary software?

QMK runs entirely on the keyboard's MCU. No bloatware is installed on the host PC. It allows for advanced behaviors like tap-dance, macros, and infinite layering that closed ecosystems physically cannot support.

Can I use VIA on a non-QMK board?
No, VIA is essentially a real-time GUI frontend that relies on QMK running in the background.
