I previously mentioned my best experience with QMK was via ErgoDox EZ's online tool, Oryx. Oryx may be the best online tool, but it is no longer my favorite.
Hello Via Configurator.
Via is a desktop tool for configuring your keyboards' firmware (QMK). I had never used it until a couple of days ago, but I have now tried it with three different keyboards (NK65, Rama M10-B, and Rama M60-A). In all three cases, it has been nothing short of amazing. I am blown away by how well it works.
Via's most impressive feature: no compiling and flashing. You make a change, and it is working on your keyboard. No need to run a
make command and then flash your board. No need to compile and watch the baking potato on the screen. 😀 It just works!
Support for Via is limited to about 40 different boards. No clue what it takes to go from "regular" QMK to Via compatible, but I hope others can make the journey soon.
