KProx is a HID (mouse + keyboard) automation firmware targeted at the M5Stack Cardputer, Cardputer Adv, and the M5Stack Atom S3. It features a DSL similar to DuckScript, an API with a web interface, and KeePass KDBX 3.1 database support for an onboard credential store via the nvme or SD card. Additionally, it includes a plethora of HID "apps," such as psCombatProx: kill processes by fighting tanks... and your computer.
