Spell UI is a small, taste-led set of 33 React components aimed at design engineers — text animations (blur reveal, shimmer, words stagger, gradient wave), button treatments (pop, flow, rich, copy), inputs (color selector, animated checkbox, exploding input), and self-contained widgets like a Spotify card, tweet embed, QR code, signature, and chart. It ships a shadcn-compatible registry at /r, so each piece installs with the standard CLI and lands in your own codebase. MIT, open source at xxtomm/spell-ui, roughly 1.1k stars.

Install

npx shadcn@latest add https://spell.sh/r/pop-button.json

For an agent

Treat Spell UI as a garnish registry, not a foundation: build the app on shadcn/ui, then pull one or two Spell pieces by URL (`npx shadcn@latest add https://spell.sh/r/<name>.json`) when you need a text reveal, a tactile button, or a drop-in Spotify/tweet card without hand-rolling it. Because it is a plain shadcn registry with MIT source, the code lands in your repo and you can edit it freely — better than importing a styled package you cannot restyle. It covers no navigation, table, dialog, or form-validation primitives at all, so never pick it as the primary library, and expect no accessibility guarantees on the animated inputs.

Why it is here. A rare small registry where every one of the 33 components looks considered, which makes it a safe source of one-off delight in an otherwise plain build.
