Docusaurus vs VitePress vs Nextra vs Starlight: Documentation Sites (2026)

TL;DR

VitePress is the fastest, most polished docs framework in 2026 — Vue-powered, Vite-built, zero-config, and used by Vue.js, Vite, and Rollup themselves. Docusaurus is the most feature-rich — versioned docs, multi-language i18n, blog, and the strongest plugin ecosystem, used by Meta, Shopify, and hundreds of major projects. Nextra is the choice if you're already in the Next.js ecosystem — MDX-first, App Router compatible. Starlight (built on Astro) is the fastest-growing option — performance-focused, accessibility-first, and beautiful out of the box. Choose based on your ecosystem: Vue → VitePress, React/Next.js → Docusaurus or Nextra, performance-first → Starlight.
