Flipper Zero alternative with KeePass integration and a tank-fighting demo game.

Strengths
  • •On-device KDBX 3.1 credential store keeps secrets off the host machine entirely.
  • •Web-based REST API means no driver installation on target systems.
  • •BLE and USB dual-mode support expands compatible device range significantly.
Weaknesses
  • •Author explicitly calls crypto unverified and labels project a toy.
  • •Rubber Ducky and Flipper Zero already dominate the HID automation market.

Post Description

https://github.com/akoerner/kprox/blob/master/img/combat_tit... https://github.com/akoerner/kprox/raw/master/img/combat_loss...

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.

Firmware can be installed with the M5Burner by searching "KProx"

DoScript – DSL for file automation with natural language syntax

Natural-language keywords plus implicit file metadata in loops make common file tasks unexpectedly readable, and the built-in --dry-run and explicit error reporting show a sensible safety-first design. It isn't revolutionary — PowerShell and dozens of RPA/DSL tools exist — but as a compact, distributable exe for teams that loathe terse shell one-liners it’s a practical, usable effort; the main gaps are cross-platform clarity and a larger ecosystem of libraries/examples.
