FeralUI
React interactions with ropes, paper, maps, and light
FeralUI collects React interactions, animation experiments, and visual tools by Sarthak Navalekar. Its live catalog includes a pull-cord switch, claw captcha, stamped date picker, crumpled notes, animated maps, and a gradient studio. The terms name five MIT packages: pullcord, playcaptcha, feral-blob, feral-fur, and animaps-react. Unpublished demos have no reuse license. Gradient Builder also documents a free MCP endpoint for gradient images and editable studio links.
Open each demo to find its package and usage guide. For example, PullCord uses npm install pullcord and its own stylesheet. Check each package LICENSE. Treat unpublished demos as references only. The documented https://feralui.dev/mcp endpoint serves Gradient Builder tools, not component installation.
Why it is here. It makes physical motion easy to study, with reusable packages for some interactions and a separate gradient tool for agents.
