Nuxt 4

The whole site is one Nuxt module. Not an app with a CMS behind it — a module you install into your own Nuxt app, which then has a website in it.

Both halves of it earn their keep

The client half gives you auto-imported composables and one renderer per page type. The Nitro half is what makes this thing indexable: a doc-cache runner holds a bounded pool of provider sockets, renders every document to HTML server-side, and serves that to crawlers and to your first paint. The live renderers are client-only by design, so without the server half a search engine would see an empty shell.
