Read 2026-11-05. Source: https://agentreadyhtml.com/vendors/nextra/ Site: Agent Ready HTML Last reviewed: 2026-11-05 # 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. ## At a glance **standards.txt** nextra ```text llms-txt = no statement markdown-negotiation = no statement markdown-twin = no statement initial-html = supports real-404 = partial vary-accept = no statement ``` 1 supports, 1 partial or announced, 4 no statement. **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.
