The Best Barebones Mechanical Keyboard

Researched by Johnny Alto · last updated July 29, 2026

Short answer: The best barebones mechanical keyboard is the Glorious GMMK PRO Barebones (75 percent, gasket, hot-swap). The GMMK PRO is the barebones a lot of people build their first real custom around: a CNC aluminum 75 percent case, a gasket-mounted plate, factory-installed screw-in stabilizers, a rotary knob, and hot-swap sockets that take 3-pin and 5-pin MX switches. The main things to weigh are what is not included, mx hot-swap sockets, match the layout to your keycaps, and firmware caveat.

Glorious GMMK PRO Barebones (75 percent, gasket, hot-swap)

The GMMK PRO is the barebones a lot of people build their first real custom around: a CNC aluminum 75 percent case, a gasket-mounted plate, factory-installed screw-in stabilizers, a rotary knob, and hot-swap sockets that take 3-pin and 5-pin MX switches. It ships as a true barebones, so nothing is included but the board itself. Two honest cons: it runs on Glorious Core software rather than native QMK or VIA, which is fine for most but a dealbreaker for firmware purists, and the specific listing is often the ISO or a particular color variant, so confirm you are selecting ANSI if you want the US layout. It is heavier and pricier than plastic barebones, but the build quality and typing feel are why it stays a default recommendation.

A barebones kit is the case, plate, PCB, stabilizers, and firmware with deliberately no switches and no keycaps, so you supply those yourself. It is for the builder who already knows which switches and keyset they want and does not want to pay for and discard a bundled set. The tradeoff is real: the sticker price looks lower, but you must budget separately for roughly 65 to 90 switches and a full keycap set before you have a usable keyboard. This is for someone ready to hand-pick every part of the build. Here is the popular pick, budget and 60 percent kits, and the hidden spend to plan for.

How do the best options for barebones mechanical keyboard compare?

What should you look for in barebones mechanical keyboard?

A few things separate a good barebones mechanical keyboard from a frustrating one: what is not included, mx hot-swap sockets, match the layout to your keycaps, and firmware caveat. Weigh these before you buy.

• What is NOT included: switches and keycaps, and sometimes not even a cable, so plan to buy about 65 to 90 switches plus a full keyset on top of the kit price before it types.
• MX hot-swap sockets: all of the above take 3-pin and 5-pin Cherry-MX-compatible switches; they do not accept optical or low-profile switches.
• Match the layout to your keycaps: GMMK PRO and GMMK 3 are 75 percent, GK87 is TKL, GK61 is 60 percent, so a keyset must cover your specific layout.
• Firmware caveat: GMMK boards use Glorious Core, not QMK or VIA, and several listings are tied to ANSI vs ISO, so confirm before ordering.

The real cost of barebones

The single most important thing to understand about a barebones kit is that the price on the listing is not the price of a working keyboard. Barebones means the manufacturer deliberately left out the two most personal and most swappable parts, the switches and the keycaps, so that you can choose exactly what you want instead of paying for a bundled set you would rip out anyway. That is a genuinely good deal for someone who already has strong preferences, but it changes the math. A full-size or TKL board needs somewhere between 65 and 90 switches, and a decent switch set plus a decent keycap set can easily cost as much as the kit itself, so the true out-the-door cost is often close to double the sticker. It also means the board does absolutely nothing until those parts arrive, which occasionally surprises first-time buyers who expected to type on it out of the box. The upside, and the reason experienced builders love barebones, is control and feel: you get the case, plate, stabilizers, and mounting style that shape the sound and typing experience, usually a nicer gasket-mounted aluminum build than a bundled board at the same price, and then you drop in exactly the switches and caps you want. If you already know your switch and keyset, barebones is the smart path. If you do not yet know what you like, an all-in-one kit that includes switches and caps is the better starting point, and you can always go barebones for your second build.

What are the best alternatives?

Bottom line: the GMMK PRO is the aluminum gasket barebones most first builds are based on, GMMK 3 is the newest platform, and the GK87 and GK61 are the budget TKL and 60 percent options. Remember to budget for switches and keycaps on top. Compare it with our beginner custom kit guide and our switch spring guide.
