Geist font family for Svelte and SvelteKit including Sans, Mono, and Pixel variants

I love the Geist fonts so much that I use them in most of my projects. But as a Svelte dev, I didn’t want to miss the convenience of the npm package for Next.js. So I built a simple and easy-to-use version for Svelte. It also contains the new Pixel variants

Jacob Paris Pretty much any database would be a good fit for your project. The harder part will be a user login feature, so if you don't have any opinions of your own about it I'd recommend picking either Neon or Supabase since they have auth login systems built in, and they can also store your other data.
