Does Inertia support server side rendering (SSR)?

Yes. Inertia supports SSR through a Node.js process that pre renders pages on the server. SSR improves Core Web Vitals scores (LCP and CLS) and is important for SEO on public facing pages. We configure Inertia SSR through Laravel Forge or Vapor, with the SSR Node process running alongside the Laravel application. SSR adds operational complexity (one more process to monitor) so we recommend it for public facing applications where SEO matters, not for admin panels or authenticated dashboards.
