Five design languages. One engine.
Sveltier is a UI framework for Svelte 5: one shared system for theme, defaults, density and layout, a wide set of components built on it, and five design languages you switch with one line. Made to be written quickly and correctly, by developers and by AI coding agents.
Principles
- Fast Zero runtime dependencies, a size budget on every entry, flash-free server rendering.
- Predictable One prop vocabulary, strict types, a typed theme contract and errors that say how to fix them.
- Accessible Keyboard behaviour from the WAI-ARIA Authoring Practices; every theme passes WCAG contrast checks.
- Luxurious Monolith, Heritage, Aurora, Maison and Milano: complete design languages, not colour swaps.
Five design languages
Each tile is a nested ThemeProvider. Apply one to the whole site.
Monolith
Quiet luxury with Swiss precision. Monochrome, ink-black actions; colour only carries meaning. The pack to start with.
$248,190.35
Heritage
Private banking, editorial. Ivory paper, Oxford navy and brass, ruled lines.
$248,190.35
Aurora
Modern depth, dark first. Frosted panels over a soft iris and mint glow.
$248,190.35
Maison
Parisian couture house. Noir and off-white, a single Bordeaux accent, nothing superfluous.
$248,190.35
Milano
Milanese design. Cashmere cream, espresso brown and Siena terracotta; warm and tactile.
