Next.js is a go-to choice for React teams because it combines routing, server rendering, and full-stack capabilities in one widely adopted framework. The alternatives landscape splits into a few clear camps: Astro focuses on content-first sites with islands architecture and optional hydration, Gatsby leans into a GraphQL-driven data layer for static builds, and Eleventy keeps things minimal and flexible for HTML-forward static sites. For documentation specifically, Docusaurus offers a batteries-included docs platform, while Fumadocs takes a different angle by layering a polished docs system directly on top of Next.js.
In evaluating these options, we looked at performance and JavaScript payload defaults, content and MDX/Markdown workflows, docs-specific features (navigation, search, versioning), build speed and iteration ergonomics, integration flexibility (including multi-framework support and data sourcing), and practical deployment considerations like CDN-friendly output and potential platform coupling.
