Akko Cloud Driver vs Piper

Akko Cloud Driver is free software for configuring selected Akko keyboards and the AG ONE 8K mouse. It supports custom RGB settings, macro programming, online firmware upgrades, polling rate control, and sensitivity controls. Akko offers version 4 downloads for Windows and Mac, plus browser-based keyboard and mouse drivers for selected models. Which devices work depends on the driver version, so users need to check the model-specific software list. The driver is not compatible with all VIA/QMK models, and Akko says VIA/QMK keyboards do not support Akko Cloud Drivers. Connection limits vary: the web driver uses HID and does not support wireless connections, while the Mac app driver does not support Bluetooth. On Mac, customization over Bluetooth is unavailable and some functions, including Audio Visualizer, are not offered. The Mac browser driver requires Chrome; Safari and Firefox are unsupported. Akko provides compatibility guidance in its FAQ and directs users to the download page for model-specific software. Akko says it was founded in Shenzhen, China, in 2016.
