Karabiner-Elements is a powerful, open-source keyboard customizer and key remapper for macOS, offering both simple key swaps via a GUI and highly flexible condition-based complex modifications defined in JSON. It captures keyboard input events at a low level and rewrites them per user-defined rules, with a large library of community-maintained predefined rules.

Use cases

• remap caps lock to escape on macOS
• swap command and control keys on a Mac keyboard
• use vi or emacs key bindings system-wide
• disable the built-in keyboard when an external keyboard is connected
• change keys only in specific applications
• map mouse buttons or trigger shell commands from key presses
• fix keyboard shortcuts after switching to an external PC keyboard

When to choose

• you need deep, condition-based key remapping on macOS beyond what System Settings offers
• you want to import community rules like Emacs/Vi bindings or mouse keys
• you prefer a free, open-source tool with no telemetry of your keystrokes
• you need per-device, per-app, or input-source-specific key behavior

When to avoid

• you are on Linux or Windows - it is macOS-only
• you only need trivial remapping that macOS built-in settings already cover
• you cannot grant Accessibility/Input Monitoring permissions due to managed device policies
