Where each one falls short

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

IINA

  • There is no Apple TV or iOS app, so it cannot be used for a living room streaming setup the way Infuse can.
  • It has no polished network share or cloud storage library browser, so streaming from a NAS or cloud drive is more manual than with Infuse.
  • As a volunteer open source project, new feature development and bug fixes depend on contributor availability rather than a funded team.
  • It is Mac only, so there is no equivalent app for Windows users in a mixed household.
  • Advanced mpv configuration is still exposed for power users, which can be confusing for someone who just wants simple playback with no options.

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.
