2023 was truly the year of Haute42, a company that has produced so many slim and affordable leverless controllers, and other companies performed well too.
The PXN-008 is a sibling of the PXN-X8. It is made of ABS for the purposes of durability and being waterproof & resistant to fading.
The Steelbox is a mini stickless controller that has 14 buttons and switches, with the jump button being bigger than the rest.
The Paragon is a wooden stickless controller that has its own layout (unless you choose the standard layout).
The Caster Acrylic & Resin Fightstick DIY Enclosure by Raw Super Arcade comes in Vewlix, Noir, all button, and other layouts.
The DRMFTG DRM FL packs a lot of innovation, including many layouts, if you are willing to primarily use it on a desk.
Perhaps the most interesting aspect about the Sunga G1 stickless controller is that it has five more buttons than what we are used to.
The Slab MX is a bigger version of the bestselling Slab Mini, and it comes with innovations like rubber bumpers.
When not making wooden accessories for tech, StepUpSFF makes stuff like the Retro Lever-less Arcade Controller (also in WASD format).
