Haptyk vs Klack vs Mechvibes: which keyboard sound app for Mac?
Three apps make a MacBook sound like a mechanical keyboard, and they are built on three different ideas. Klack is a polished $4.99 native app from the Mac App Store. Mechvibes is free, open source and runs everywhere. Haptyk is the only one that reads how hard you press and plays a matching sound, because it uses the accelerometer hidden inside Apple Silicon MacBooks.
Prices and features below come from each app's own site or App Store listing, checked in October 2026. If something changed, tell us and we will fix it.

Who should pick what
An honest recommendation
Pick Klack if you want the cheapest polished option
Klack is $4.99 once, lives in the menu bar, ships recorded switch sets with spatial audio and randomized pitch, and works on any Mac, Intel included. There is no trial, but the App Store handles refunds. The one thing it cannot do is react to your typing force: every press plays at the same level.
Pick Mechvibes if you want free, or you are not on a Mac
Mechvibes costs nothing, is open source under the MIT licence, and runs on Windows, macOS and Linux with hundreds of community sound packs. The 2.x app is built on Electron (the macOS download is about 97 MB) and some people report silence on recent macOS versions until Input Monitoring is set up. A Rust rewrite, MechvibesDX, is in progress.
Pick Haptyk if you type on an Apple Silicon MacBook and want the sound to follow your hands
Haptyk reads the motion sensor inside the MacBook about 1,000 times a second, measures the impact of each keystroke and picks one of four sound levels, from a brushed key to a slam. Soft typing sounds soft, hard typing sounds loud, the way a real board behaves. It costs $3 more than Klack ($8 once), comes with 16 recorded packs and a 3-day trial so you can hear the difference on your own Mac before paying. It only works on MacBooks that have the sensor: MacBook Pro 14″ and 16″ (M1 Pro and later), MacBook Air M2 and later, and the 13″ MacBook Pro M2.

FAQ
Questions people ask before choosing
Is Haptyk free?
No. Haptyk has a 3-day trial with every sound pack unlocked and no credit card, then Pro costs $8 one time. There is no subscription and every update is included. If you want a free app, Mechvibes is free and open source.
Klack or Haptyk?
Klack if you want the cheapest native option ($4.99 once) or you are on an Intel Mac. Haptyk if you type on an Apple Silicon MacBook and want the sound to react to how hard you press, which no other app does. Haptyk costs $3 more and lets you try it for 3 days first.
Is Mechvibes safe?
The official Mechvibes is open source on GitHub under the MIT licence, and its developer has stated that it only contacts GitHub to check for updates. Download it from mechvibes.com or the GitHub releases page only. Unofficial builds such as "Mechvibes++" are not from the same project and have triggered antivirus warnings for some people.
Does any of these work on Windows?
Mechvibes does (Windows, macOS and Linux). Klack and Haptyk are Mac only. Haptyk cannot come to Windows as is, because it depends on the accelerometer inside Apple Silicon MacBooks.
Which Macs does Haptyk run on?
MacBook Pro 14″ and 16″ with M1 Pro, M1 Max or any later chip, MacBook Air M2 and later, and the 13″ MacBook Pro M2. The M1 MacBook Air, the 13″ M1 MacBook Pro, Intel Macs and desktop Macs do not have the sensor, and the app tells you at launch, before any email or payment.
Do these apps record what I type?
Haptyk only needs to know that a key went down and how hard; it never records which keys or sends keystrokes anywhere. Klack and Mechvibes also state that they do not log typing. All three need a macOS permission (Accessibility or Input Monitoring) to hear key events system-wide; that is how any keyboard sound app works.
