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.; Rclone sync deletes files at the destination to make it match the source, so one transposed argument between source and destination can wipe a backup and there is no undo.
  • They diverge on capability: Karabiner-Elements covers Low-level key remapping, Rclone covers Unified backend model.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Karabiner-Elements

  • Someone switching from a Windows or Linux keyboard layout who wants familiar modifier positions on a Macnot Rclone
  • A user with an accessibility need around key repeat rate or modifier key behaviour that macOS settings cannot covernot Rclone

  • Nightly one-way sync from an on-premises NAS to cloud storage as a second copynot Karabiner-Elements

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.

Rclone

  • Sync deletes files at the destination to make it match the source, so one transposed argument between source and destination can wipe a backup and there is no undo.
  • Google Drive throttles the shared default OAuth client, so large jobs stall until you register a private API client ID, a step that is documented but easy to miss until a migration is already days behind.
  • Millions of small files hit per-provider request ceilings rather than bandwidth limits, which makes transfer time nearly impossible to estimate from data volume alone.
  • The FUSE mount is not a real filesystem; applications that expect POSIX locking, partial writes or fast directory listings will behave badly or corrupt state on network interruption.
  • Support is a community forum and a single principal maintainer, so an organisation that needs contractual response times on a data movement tool has no vendor to buy that from.

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.

Rclone: Does rclone cost anything at scale?

The software does not. Your storage provider bills egress and API requests, and a failed transfer that retries pays those charges twice.

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

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

Rclone: Can I use it as a backup tool?

It copies and syncs but does not do versioned incremental backup by default. Use it under a backup tool, or use its own crypt and backup-dir options deliberately.

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.

Rclone: Why is my Google Drive transfer so slow when my link is fast?

You are almost certainly rate limited on the shared OAuth client. Create your own client ID in Google Cloud Console and configure the remote to use it.
