Where each one falls short

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

Jellyfin

  • No commercial support or SLA available; project is volunteer-maintained
  • Self-hosted deployment required; no cloud hosting provided by project

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.
