Finding keycaps for split and ergonomic keyboards is hard. Non-standard key sizes, thumb clusters, and unique row assignments make most off-the-shelf sets incompatible, and sculpted keycap sets designed for specific layouts are genuinely rare. Options are limited, and building a matching set usually means mixing and matching through trial and error.
The Custom Keycap Set Builder simplifies and clarifies this whole process. Design a fully custom keycap set for your exact layout.
