About:
KeyCastr is an open-source keystroke visualizer for macOS that overlays your keyboard shortcuts and typing on screen. It is especially useful for presentations, streaming, and creating tutorials where you need to show your input clearly to an audience. The tool is highly customizable, supporting different visual themes and output formats.
Key Features:
  • On-screen overlay of keystrokes and shortcuts
  • Support for modifier key combinations (Cmd, Ctrl, Alt, etc.)
  • Customizable appearance and themes
  • Option to display mouse clicks
  • Lightweight and easy to configure
Use Cases:
  • Live software demonstrations and presentations
  • Creating screencasts and tutorial videos
  • Remote support and collaborative debugging
  • Accessibility aid for visualizing keyboard input
Alternatives:
  • CheatSheet – Focuses on displaying app-specific shortcut menus rather than live keystroke visualization.
  • KeyCastOW – Windows-focused tool; KeyCastr is the native macOS equivalent.
