Working with this library

Verified 2026-10-03 from the official introduction, repository README and MIT LICENSE. The captured www.melt-ui.com site documents @melt-ui/svelte builder functions and the melt action, with an optional @melt-ui/cli initializer. Builders provide behavior/attributes rather than a fixed styled component tree; TypeScript and SvelteKit support are explicitly documented. The canonical homepage links to next.melt-ui.com, its next-generation Svelte 5/Runes track; treat this as the same library family, not a second new identity. The captured documentation warns of possible minor-version breaking changes before 1.0. Check the relevant version track before adopting and do not mix old builder examples with the Svelte 5 track. Free MIT-licensed core. Editorial: useful when you need control over markup and styling, at the cost of assembling and testing your own components. Maintainer accessibility claims are not an independent conformance guarantee.
