MintlifyAstro Starlight + NextraBiome
Quick read
- Free with no card: Astro Starlight + Nextra, Biome.
| Field | Mintlifymintlify.com | Astro Starlight + Nextrastarlight.astro.build | Biomebiomejs.dev |
|---|---|---|---|
| What it is | A hosted documentation platform: write MDX and get a polished docs site with search, an API playground generated from an OpenAPI spec, and analytics. The CLI is source-available under Elastic-2.0 rather than a true open-source licence. The free Starter tier includes five editor seats. | Two batteries-included docs themes. Nextra (v4) turns a Next.js app into a docs or blog site from Markdown files with almost no config. Astro Starlight builds fully static docs with near-zero client JavaScript, plus built-in i18n, search and dark mode. | A single Rust binary that replaces both ESLint and Prettier, at v2.5 with over 500 lint rules, GritQL plugins and a watch mode. It formats and lints JS, TS, JSX, JSON and CSS in one pass, typically many times faster than the tools it replaces. |

| Why builders pick it | The fastest path from zero to docs that look like Stripe's, with no build config to maintain. Worth it when docs are a product surface, unnecessary if a README will do. | Starlight is the fastest way to ship docs when you have no Next.js app — one command, drop in Markdown, done. Nextra fits when docs live inside an existing Next.js codebase. | One dependency and one config file instead of a dozen ESLint plugins that fight Prettier over semicolons. For a solo builder it removes the single most annoying setup step in a new repo. |
| Watch out for | The only genuinely commercial tool in this list, and Pro is a steep $450/mo jump from free. You are renting hosting and lock-in — Fumadocs or Starlight are the self-hosted answers. | Nextra is more theme than framework, so deep customisation means fighting it, and Fumadocs has taken much of its mindshare. Starlight is still pre-1.0 and needs an Astro project. | Rule coverage still trails the full ESLint plugin ecosystem — notably some React and accessibility rules — so heavily-linted teams sometimes keep ESLint alongside it. |
| How to wire it up | npm install -g mintlify | npm create astro@latest -- --template starlight | npm install --save-dev --save-exact @biomejs/biome |
