Ranked by how well each one replaces Caramba on macOS — automatic correction, language coverage, price and privacy.
1.
Rekey
Top pick for Mac
macOS 13+ · Apple Silicon & Intel · Free · 34 languages
A native Swift app that auto-corrects text typed in the wrong layout as you go. The same core idea as Caramba, but free, on-device, and built for many languages rather than one pair. See how Rekey works →
Pros
- Free — no subscription, no account
- 34 languages vs Caramba's EN/RU focus
- 100% on-device, no telemetry, respects password fields
- Native, lightweight; excludes terminals & code editors
Cons
- macOS only (no Windows)
- Launching soon — currently waitlist
2.
Boomkey
macOS · native · manual double-Shift fix
A clean macOS utility that fixes the layout of the last word on a double-Shift press. More manual than Caramba's automatic switching, but native and focused.
Pros
- Native macOS, simple and focused
- Predictable, you trigger the fix
Cons
- Mostly manual, not automatic detection
- Limited language coverage
3.
MLSwitcher
macOS · Mac App Store · shortcut-based
A long-standing Mac App Store tool that switches the layout of selected text via a shortcut. Good for deliberate, on-demand fixes rather than automatic correction.
Pros
- Established Mac App Store presence
- Good for manual switching
Cons
- Shortcut-based, not auto-fix
- No real-time detection as you type
4.
Bzz
macOS · open source (GitHub) · free
A free, open-source layout switcher for macOS. A good pick if you value open source and do not mind installing from GitHub.
Pros
- Free and open source
- Inspectable, community-friendly
Cons
- No polished website or support
- Setup via GitHub; fewer languages
