Where each one falls short

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

AutoHotkey

  • Version 2 is a different language rather than a new release, so v1 scripts must be rewritten and the conversion script handles only routine cases, leaving years of accumulated internal automation stranded.
  • Version 1.1 receives no active development, so teams that decline the rewrite are running an interpreter that will not get fixes for future Windows changes.
  • Antivirus and EDR products frequently quarantine the interpreter and compiled scripts because the same capabilities are used by keyloggers, which turns deployment into a security exception request.
  • Automation depends on window titles, control classes and screen positions, so a vendor application update can break every script overnight with no compile-time warning.
  • It is Windows only with no path to macOS or Linux, so any process automated with it cannot follow the organisation if it moves platforms.

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.

Answered from the vendors’ own pages

AutoHotkey: Should a new project start on v1 or v2?

Version 2. Version 1.1 is not actively developed and every new script written against it adds to a future rewrite.

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.

AutoHotkey: Will compiled scripts trigger antivirus?

Often yes. Compiled AutoHotkey executables are a known malware pattern and usually need to be allowlisted by hash or signed with your own certificate.

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

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

AutoHotkey: Can it automate a web application?

It can drive a browser as a user would, but it has no page object model, so a CSS change breaks it. Use a browser automation framework where one is available.

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.
