Kamibase is mostly other people’s work, arranged.
Origami Simulator
Amanda Ghassaei, Erik Demaine and Neil Gershenfeld · MIT
Every 3D fold on this site is Origami Simulator, running in a frame and served from our own origin so it does not depend on anyone else’s uptime. Its JavaScript is unmodified. Kamibase hides the simulator’s own controls and drives it through the same message interface it already published, which is the only reason embedding it was a day of work rather than a year of it.
The FOLD format
Erik Demaine, Jason Ku and Robert Lang · MIT
FOLD is the interchange format for folded structures, and it is what made a database of crease patterns a tractable idea rather than a standards argument. Kamibase’s own .kami files are a strict profile of it: every one is a valid FOLD document, and every pattern here exports as plain FOLD.
The 13 seeded patterns
Kōryō Miura, and traditional · Public domain
The library starts with traditional bases, which belong to everybody, and with published mathematical and engineering patterns, of which the Miura fold is the best known. Nothing here is a living designer’s competition model. Patterns are added by their designers or with permission, not scraped.

The site runs on Next.js and React, is styled with Tailwind CSS, keeps accounts and folds in Supabase, and draws its icons from Lucide. The geometry, the validation and the photo pipeline are Kamibase’s own, written in TypeScript with no native dependencies, which is why reading a photograph of a creased sheet happens in your browser and nothing is uploaded to do it.
