The modern framework for fast websites

What you get

• File-based routing

  src/about.ht.js → /about

• JSX & TSX

  Write pages as .jsx / .tsx with the same routing and build

• Dynamic routes

  [slug], [...path], optional catch-alls

• Data loading

  data() at build time, with fetch caching

• Asset pipeline

  Referenced JS/TS/CSS is bundled; the rest stays server-only

• Zero JavaScript, by default

  Only the scripts you link are bundled — everything else stays off the page for a faster site

• Dev server + toolbar

  Live renders on request, plus route, file, params, and island count while you develop

• Pagefind search

  Opt-in static search — sitelo build indexes your site into dist/pagefind/

• Server islands

  Static pages with regions rendered on the server at request time

• AI-ready

  llms.txt, project rules, and tips so agents write sitelo — not React

• One-click deploy

  Netlify, Vercel, Cloudflare Pages, and AWS Amplify configs included

• Extras

  404.html, sitemap.xml, and RSS when you ask
