TweakCN is a focused shadcn theme editor. If you want the same visual ease but framework-neutral and across a whole design system, UIcockpit is the wider tool.
TweakCN nails visual shadcn theming. People look for an alternative when they need more than colour and radius, or a stack other than shadcn — both of which are UIcockpit’s home turf.
You still get a drop-in shadcn export; you just also get type, density, motion, recipes, six formats and a returnable hosted kit.
A full system — type scale, density, motion, elevation, chart palette and component recipes.
The output is plain CSS custom properties (--k-*). They drop into React, Vue, Svelte, plain HTML — anything. You are never tied to one framework to wear your own brand.
Tokens (CSS + JSON), a Tailwind @theme block, a shadcn globals.css, an AI prompt and a machine-readable contract — all derive from one config, so they can never disagree. Plus a hosted live <link> you return to, and a CLI + MCP so your agent reads the system and checks its own work against it.
100% free, framework-neutral tokens — no account, no lock-in, your design language, your file.
