Nextra: vendor profile

In short

Nextra 4 works only with the Next.js App Router and renders pages through static rendering or a static export. nextra.site served no llms.txt or robots.txt on 2026-11-05, though its sitemap answered. Search finds nothing until a pagefind postbuild step is added, and the Ask AI box relies on a third-party Inkeep widget.

Nextra Framework

Next.js App Router framework for docs and blogs whose pages use Next.js static rendering or a full static export, a NotFoundPage component fills not-found.jsx, and search needs a Pagefind postbuild step; no llms.txt or Markdown output is documented.

Nextra 4 moved search from the JavaScript FlexSearch library to Pagefind, which is written in Rust. [primary source] source, read 5 November 2026.
Nextra search needs pagefind as a dev dependency plus a postbuild script that indexes .next/server/app, writing to public/_pagefind or out/_pagefind for static exports. [primary source] source, read 5 November 2026.
Nextra's docs describe Next.js static rendering as the default strategy, with routes rendered at build time or in the background after revalidation, so docs pages reach crawlers as HTML. [primary source] source, read 5 November 2026.
A fully static Nextra site sets output: 'export' and images.unoptimized: true in next.config.mjs and writes the export to the out directory. [primary source] source, read 5 November 2026.
nextra-theme-docs provides a NotFoundPage component for app/not-found.jsx whose default top content is an H1 reading "404: Page Not Found", plus a link that opens a broken-link issue. [primary source] source, read 5 November 2026.
Nextra 4.5.0 added a copyPageButton layout prop that shows or hides the copy page content button, the closest thing Nextra has to a Markdown export. [primary source] source, read 5 November 2026.

What it does not do

Nextra has no llms.txt generator in its docs or changelog, and nextra.site serves no /llms.txt.
Nextra's search is not indexed at build by default; a project must add the pagefind postbuild script or the search box finds nothing.
