Add flexible server-side rendering to Vite-based projects without committing to a full framework like Next or Nuxt.

Convert Svelte apps into SEO-friendly static sites during the build process using the '@sveltejs/adapter-static' package.

A zero-config pre-rendering tool for React apps that crawls your site and saves each route as a static HTML file.

Use Gatsby's GraphQL data layer to generate highly optimized static pages with pre-integrated SEO plugins for React.

Manage the document head in React apps; use the async version to prevent memory leaks and ensure thread safety during SSR.

Standardize metadata management for Vue 3 apps, allowing dynamic updates to titles and meta tags based on component state.
