Custom keyboards let you pick the exact layout, switches, and firmware. QMK and ZMK firmware support layers, macros, and per-key remapping. You get a tool shaped to how you actually work, not a compromise for mass production.

A small keypad (3 to 12 keys, sometimes with a rotary encoder) that runs custom shortcuts. Developers use them for IDE commands, git workflows, media controls, or stream deck functions. Most run QMK or ZMK firmware.

Hot-swap sockets let you change mechanical switches without soldering. Pull out one switch, push in another. This lets you test different switch types (linear, tactile, clicky) until you find your preference.
