Crucible

Overview

Crucible is a library of animated React components designed for dark interfaces, with original shaders, physical motion and accessibility built in. The site counts 238 components across 14 categories, from fullscreen WebGL backgrounds to full landing sections and app UI. Of those, 114 are free with previews, source and CLI install, and the remaining pro components are sold as a single lifetime purchase.

Every animated component ships with reduced-motion fallbacks, offscreen pausing and an exported props contract. Components install through the shadcn CLI, by copy-paste from the code tab, or through Crucible's MCP server for coding agents. Every preview on the site is the shipped component running live.
