Where each one falls short

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

CCleaner

  • Registry cleaning has little measurable benefit on modern Windows and carries some risk of removing something needed
  • The free version prompts toward the paid one persistently
  • A 2017 supply chain compromise distributed malware through an official signed build, which permanently changed how some administrators view it
  • Much of what it does is achievable with the disk cleanup tools built into Windows

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

CCleaner: Is CCleaner free?

There is a free version, with a paid Professional tier adding scheduled cleaning and real-time monitoring.

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.

CCleaner: Does registry cleaning actually help?

Very little on modern Windows. The measurable gains come from clearing caches and controlling startup programs, not from the registry.

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

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

CCleaner: Is CCleaner safe?

It is a mainstream product from Gen Digital, though a 2017 supply chain attack distributed malware via an official build. That was resolved, and it remains a fair reason some administrators avoid it.

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.
