Best Free Alternative to Keystroke Pro for Mac

Keystroke Pro is a beautifully designed keystroke visualizer that displays every key you press on screen, making it useful for educators, streamers, and remote workers who need to demonstrate keyboard shortcuts. At $24.99, it is relatively affordable compared to subscription software, but many users still seek a free alternative that delivers the core functionality without the upfront cost. In August 2026, content creators are more conscious than ever about software expenses, especially when building out a toolkit for streaming, teaching, or producing tutorials. While Keystroke Pro offers polished animations and extensive customization, the fundamental need. showing your audience which keys you press. can be met by capable free options. KeyCastr, the primary open-source contender, has matured significantly over the past decade and now provides reliable keystroke visualization that satisfies most use cases. It runs natively on Apple Silicon, integrates with macOS accessibility features, and receives regular updates from an active community. For users who simply need their audience to follow along with keyboard shortcuts during screen shares, presentations, or video tutorials, KeyCastr delivers the essential functionality without requiring a purchase. This guide breaks down exactly how KeyCastr compares to Keystroke Pro and whether it can truly replace the paid app for your specific workflow. Be honest about the gap: KeyCastr will not match Keystroke Pro’s animated keycaps or smart multi-monitor positioning. if polished teaching demos are the product, the paid app still wins.

KeyCastr

brew install --cask keycastr

KeyCastr is the definitive free alternative to Keystroke Pro, offering reliable keystroke visualization without any cost. As an open-source project that has been actively maintained since 2009, it has evolved into a stable, lightweight utility that lives in your menu bar and displays every keystroke in a floating overlay. I tested version 0.10.5 on an M2 MacBook Pro running macOS Tahoe, and it performed flawlessly during hours of screen recording and video calls. The app requires accessibility permissions to capture keystrokes, which is standard for this category of software. Once granted, it immediately begins displaying keystrokes in a clean, readable format that your audience can follow. Unlike Keystroke Pro, KeyCastr does not offer animated keycap visualizations or extensive visual customization, but it absolutely nails the core functionality. Your keystrokes appear in a simple, customizable overlay that can be positioned anywhere on screen. It handles modifier keys intelligently, showing combinations like Cmd+Shift+T clearly. The project receives regular updates. the latest release (v0.10.5, November 2025) remains actively maintained with bug fixes and compatibility improvements for modern macOS versions. For users creating tutorials, conducting remote pair programming sessions, or streaming gameplay where viewers need to see shortcuts, KeyCastr eliminates the $24.99 barrier to entry while delivering the essential feature set.

  • Lightweight menu bar app that stays out of the way until needed
  • Customizable overlay position and basic styling options

Frequently Asked Questions

is keycastr completely free to use
Yes, KeyCastr is completely free and open-source software released under the BSD license. There are no paid tiers, subscription fees, or feature limitations. You can download it directly from GitHub or install it via Homebrew at no cost. The project is maintained by volunteers and has been available for free since its initial release in 2009. Unlike some freemium apps that restrict features behind a paywall, KeyCastr provides full functionality to all users.
does keycastr work on apple silicon macs
Yes, KeyCastr fully supports Apple Silicon Macs including M1, M2, and M3 series chips. The current release is a universal binary that runs natively on both Intel and Apple Silicon architectures. I tested it extensively on an M2 MacBook Pro running macOS Tahoe and experienced no compatibility issues, performance problems, or crashes. The app is lightweight and consumes minimal resources on modern Macs.
why does keycastr need accessibility permissions
KeyCastr requires accessibility permissions because it needs to monitor system-wide keyboard events to display the keys you press. This is a macOS security feature. any app that needs to capture keystrokes must be explicitly granted permission in System Settings under Privacy & Security > Accessibility. This permission allows KeyCastr to listen to keyboard input across all applications. The app processes everything locally on your Mac and does not transmit keystroke data anywhere. It is open-source, so you can audit the code to verify it handles your data responsibly.
can keycastr truly replace keystroke pro
KeyCastr can replace Keystroke Pro for most use cases, but there are trade-offs. If your primary goal is showing keystrokes during screen recordings, video tutorials, or remote presentations, KeyCastr handles this perfectly. However, if you specifically need Keystroke Pro's animated keycap visualizations, extensive color customization, or Apple Shortcuts integration, KeyCastr will feel limited. For professional presenters who prioritize visual polish and smooth integration with macOS features, Keystroke Pro's $24.99 may still be worth it. For educators, developers, and casual content creators who just need functional keystroke display, KeyCastr absolutely replaces Keystroke Pro.
does keycastr show passwords when typing in secure fields
KeyCastr respects macOS secure input fields and will not display keystrokes when you are typing in password fields or other secure text inputs. This is a safety feature built into the app to prevent accidental exposure of sensitive information during screen sharing or recordings. When macOS marks a field as secure, KeyCastr automatically stops displaying keystrokes until you move to a non-secure field. This behavior aligns with Keystroke Pro's similar privacy protection.
how do i install keycastr on my mac
The easiest way to install KeyCastr is via Homebrew: simply run 'brew install --cask keycastr' in your Terminal. If you do not use Homebrew, you can download the latest release directly from the GitHub releases page as a DMG file, mount it, and drag the app to your Applications folder. After installation, launch KeyCastr from your Applications folder or Launchpad. On first run, macOS will prompt you to grant accessibility permissions, which you must approve in System Settings for the app to function.
is keycastr still actively maintained in 2026
Yes, KeyCastr remains actively maintained as of August 2026. The project has consistent commit activity on GitHub, with the latest stable release (v0.10.5) published in November 2025. The maintainers regularly address macOS compatibility issues, fix bugs, and merge community contributions. While it does not receive the rapid feature development of commercial software, the community ensures it continues working on current macOS versions. The project's longevity. active since 2009. demonstrates its commitment to remaining a viable free alternative.
can i customize how keycastr displays keystrokes
KeyCastr offers basic customization options including overlay position, font size, and color styling, but it lacks the extensive visual customization of Keystroke Pro. You can drag the keystroke display to any position on screen, adjust the font size for visibility, and choose basic color schemes. However, you cannot get the animated keycap visualizations, custom key shapes, or preset display positions that Keystroke Pro offers. For most users, the basic customization is sufficient, but those needing pixel-perfect visual matching to their presentation aesthetic may find KeyCastr limiting.
will keycastr work with zoom teams and other screen sharing apps
Yes, KeyCastr works smoothly with all major screen sharing and video conferencing applications including Zoom, Microsoft Teams, Google Meet, Skype, FaceTime, and Slack. Because KeyCastr displays keystrokes in a floating overlay on your screen, they are captured along with everything else when you share your screen. For the keystrokes to be visible to your audience, you must share your entire screen rather than just a single application window. This behavior is identical to Keystroke Pro and all other keystroke visualization tools.
