What is this?
Bead Grid Studio is a local-first tool that turns an image into an editable, printable fuse-bead (pindou) pattern, with auto color matching, grid coordinates, and material usage stats.

Only developers who want to build from source need Node.js 22.12 or higher.

Only developers who want to build from source need Node.js 22.12 or higher.Will small grid sizes reproduce my image perfectly?No — a 16x16 grid only has 256 cells, so details smaller than one bead (fine lines, small text, reflections) can't all be represented; the tool protects what structure it can and reports what it can't fit instead of faking perfection.
