Overview

Why another SSG?

This project was created from the need to manage sites with millions of pages, with making static site generation a primary use case, and SEO optimisation its first goal.

Philosophy

This framework was created to address several things that are lacking in current frameworks:

1. SEO first
2. Links and URLs first
3. Designed for websites with millions of pages

• 👍 Each page is it's own SPA. Fully autonomous.

• 💪 ESM first, no more enormous CommonJS bundles, thanks to Esbuild.
• 🕸️ Out of box SEO features: metatags, i18n, web vitals, robots, sitemap, etc.
• 🏠 Host anywhere. It's just HTML files with bunch of CSS and JS files.
• ⚡️ You can generate one URL or millions. No need to rebuild whole website each time.
• 😎 Development Experience is our priority!
• 5️⃣ Supports Svelte 5.
