Open source · Config-driven · Fork and ship
Buttercut is an open-source Next.js theme for personal sites, portfolios, and product pages — distilled from kaichen.dev.
This site documents the theme itself: design tokens, interactive components, a live widget sandbox, and a fork-and-deploy guide. It is not a demo personal profile — fork the repo to build your own.
Edit site.config.ts for structure and integrations; edit content/demo/ for copy. Home pages compose from magazine cards and registered blocks.

Design tokens, UI primitives, live widgets you can try in Sandbox, and a fork guide — everything on this site is about the theme, not a sample profile.
