Keyviz is an open-source tool written in Dart/C++ that visualizes your keystrokes and mouse actions in real-time, overlaying them on screen.

Shows key-down and key-up events with configurable highlighting
Filter specific keys or hide unwanted inputs via hotkey filters
Works across multi-monitor setups
Customizable UI styling and size options
GPL‑3.0 open‑source and actively maintained
