The short version

  • Each has a real cost: Karabiner-Elements it requires granting significant system-level permissions, including input monitoring, which some security-conscious users are reluctant to allow.; Ventoy the repository ships prebuilt binaries that are difficult to reproduce from source, so several Linux distributions refuse to package it and security teams in regulated organisations will usually reject it.
  • They diverge on capability: Karabiner-Elements covers Low-level key remapping, Ventoy covers In-place ISO boot.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Karabiner-Elements

  • It requires granting significant system-level permissions, including input monitoring, which some security-conscious users are reluctant to allow.
  • Writing custom complex modification rules by hand means editing JSON, which is a real barrier for a non-technical user without the community rule library.
  • It only remaps keyboard input, so a user who also wants gesture or window management customisation needs a second tool such as BetterTouchTool or Rectangle.
  • Being an unpaid open source project, support depends on GitHub issues and community forums rather than a vendor support desk with guaranteed response times.
  • It is Mac only, so it does nothing for remapping needs on a Windows or Linux machine in the same household.

Ventoy

  • The repository ships prebuilt binaries that are difficult to reproduce from source, so several Linux distributions refuse to package it and security teams in regulated organisations will usually reject it.
  • Development depends on one maintainer, so a period of inactivity leaves compatibility fixes for new distribution releases unaddressed with no second party able to cut a release.
  • Secure Boot works only after enrolling the Ventoy certificate through MokManager at the machine, which is a manual step at every device and is blocked outright on locked-down corporate firmware.
  • A small number of images still fail to boot in place and need workarounds, so a technician can discover mid-job that the one ISO they need is the one that does not work.
  • The data partition is exFAT by default, which means no file permissions and no journal, so a stick pulled during a copy can corrupt the whole image set rather than one file.

Answered from the vendors’ own pages

Karabiner-Elements: Is Karabiner-Elements really free?

Yes, entirely. It is open source under the MIT licence with no paid tier, though the project accepts voluntary donations.

Ventoy: Can I still use the USB stick for ordinary file storage?

Yes. The data partition mounts as normal removable storage and files that are not bootable images are simply ignored by the menu.

Karabiner-Elements: Does it work on Apple Silicon Macs?

Yes, versions from 14 onward run natively on M1 through M4 chips.

Ventoy: Do I need to reinstall Ventoy when a new distribution version comes out?

No. Delete the old ISO and copy the new one. You only rerun the installer to upgrade Ventoy itself.

Karabiner-Elements: Do I need to write JSON to use it?

Not necessarily. Simple key swaps use a GUI, and complex modifications can be imported from a public community rule library instead of writing rules by hand.

Ventoy: Is it safe to use in a company that audits open source?

Often not. The unreproducible prebuilt binaries in the repository are a genuine audit finding and have blocked approval at organisations with supply chain review.
