Better Auth UI for Svelte 5

better-auth-ui-svelte provides pre-built, customizable authentication UI components designed specifically for integration with the Better Auth backend in Svelte 5 applications. Currently at version 0.12.4, this library is in active early stage development, cautioning users that it is not yet battle-tested in production environments and issues may arise before a v1.0 stable release. The package aims for a rapid iteration cycle, with minor and patch releases occurring frequently as seen in its recent history (multiple patch and minor releases within months). A key differentiator is its full feature parity with the original Better Auth UI React library, leveraging Svelte 5 runes and modern practices, while also introducing Svelte-specific utilities like path helpers. It is styled with Tailwind CSS v4 and built upon shadcn-svelte components, offering extensive customization options out-of-the-box. The library supports Zod 4 for form validation and is localization-ready, but users should be aware that this Svelte port may diverge from the React version's API and features over time.
