Show HN: Mantle – Remap your Mac keyboard without editing Kanata config files I built Mantle because I wanted homerow mods and layers on my laptop without hand writing Lisp syntax. The best keyboard remapping engine on macOS (Kanata) requires editing .kbd files which is a pain. Karabiner-Elements is easy for simple single key remapping (e.g. caps -> esc), but anything more wasn’t workin out for me. What you can do with Mantle: - Layers: hold a key to switch to a different layout (navigation, numpad, media) - Homerow mods: map Shift, Control, Option, Command to your home row keys when held - Tap-hold: one key does two things: tap for a letter, hold for a modifier - Import/export: bring existing Kanata .kbd configs or start fresh visually Runs entirely on your Mac. No internet, no accounts. Free and MIT licensed Would love feedback, especially from people who tried Kanata or Karabiner and gave up https://getmantle.app/ March 6, 2026 at 11:26PM
