KeyCastr Alternative: Keystrokes On Screen, Actively Maintained
KeyCastr is free but goes long stretches without updates. Notchy's Keystroke HUD shows every shortcut as a notch island for demos and screencasts, for the same $0 — plus 50+ other tools.
Why use Notchy instead of KeyCastr?
- Actively maintained
KeyCastr is a community project with gaps between releases. Notchy's Keystroke HUD ships as part of an app updated regularly via Sparkle.
- Secure-input safe
Notchy honors macOS secure input, so password fields are never captured — only your intentional demo keystrokes surface as islands.
- One app instead of two
KeyCastr only displays keystrokes. Notchy displays them too, and adds AI usage tracking, window snapping, a clipboard manager, and 50+ other tools — all free.

KeyCastr alternative — FAQ
Is Notchy a good KeyCastr alternative?
Yes. KeyCastr is a free, open-source keystroke visualizer that's gone through long stretches without updates. Notchy's Keystroke HUD does the same job — showing every shortcut you press as an island — actively maintained, inside an app you're already running.
How does Notchy's Keystroke HUD work?
Turn it on and every keypress surfaces as a brief island in the notch — ideal for demos, screencasts, and pair-programming sessions where your audience needs to see your shortcuts. It listens with a listen-only tap so typing is never delayed, and macOS secure input means passwords can never appear.
Is Notchy's keystroke display safe to use while typing passwords?
Yes. macOS secure input is honored, so password fields are never captured or displayed — only regular keystrokes surface as islands.
What does Notchy add beyond keystroke display?
KeyCastr only shows keystrokes. Notchy shows them too, and adds AI usage tracking, window snapping, a clipboard manager, a Pomodoro timer, and 50+ other tools — all in one free, actively updated app.
