Read 2026-11-05. Source: https://agentreadyhtml.com/vendors/react-router/ Site: Agent Ready HTML Last reviewed: 2026-11-05 # React Router: vendor profile In short A default React Router 8.5.1 app returned a 404 with an H1 of 404 for a made-up path, but its welcome page has no H1 element and the build serves no robots.txt, llms.txt or sitemap.xml. The create-react-router template can add a React Router Agent Skill. React Router 8.0.0 shipped on 2026-06-17, and the reactrouter.com footer names Shopify. ## At a glance **standards.txt** react-router ```text llms-txt = no statement markdown-negotiation = no statement markdown-twin = no statement initial-html = supports real-404 = supports vary-accept = no statement ``` 2 supports, 0 partial or announced, 4 no statement. **React Router** Framework React Router v7 and later is the merged successor of Remix. In framework mode it server-renders documents by default (ssr: true), can prerender listed paths to static HTML, and sets 404 status codes from loaders.
