Developer Experience

Mintlify

npx mintlify dev  # Local preview
git push          # Deploy automatically

Write MDX files. Push to GitHub. Mintlify deploys automatically. The API playground auto-generates from your OpenAPI spec. Zero build configuration.

DX verdict: Best for teams that want docs up in 30 minutes with zero configuration.

Nextra

npx create-next-app --example https://github.com/shuding/nextra-docs-template
npm run dev

Nextra is a Next.js plugin. Full access to React components, Next.js features (SSR, ISR), and the React ecosystem.

// pages/api/users.mdx
import { Callout, Tab, Tabs } from 'nextra/components'

# Users API

<Tabs items={['cURL', 'JavaScript', 'Python']}>
  <Tab>```bash
  curl https://api.example.com/users
  ```</Tab>
  <Tab>```javascript
  const res = await fetch('https://api.example.com/users')
  ```</Tab>
</Tabs>

DX verdict: Best for teams already using Next.js who want full control.

Starlight

npm create astro@latest -- --template starlight
npm run dev

Astro-powered, content-first. Supports MDX with components from any framework (React, Vue, Svelte). Incredibly fast builds.

---
title: Users API
description: Create and manage users
---

import { Tabs, TabItem } from '@astrojs/starlight/components';

<Tabs>
  <TabItem label="cURL">```bash
  curl https://api.example.com/users
  ```</TabItem>
  <TabItem label="JavaScript">```javascript
  const res = await fetch('https://api.example.com/users')
  ```</TabItem>
</Tabs>

DX verdict: Best for content-heavy docs with maximum performance.

Performance

	Mintlify	Nextra	Starlight
Build time (100 pages)	N/A (managed)	~30s	~10s
Page weight	~150KB	~200KB	~50KB
Lighthouse score	90+	85+	95+

Starlight wins on performance — Astro ships zero JavaScript by default. Pages are pure HTML with JS only where interactive components exist.

Design

All three look good out of the box:

• Mintlify: Most polished default theme. Custom brand colors, logos, and fonts via config.
• Nextra: Clean, minimal. Customizable with CSS/Tailwind.
• Starlight: Modern, accessible. Built-in sidebar navigation. Customizable with CSS.

Winner: Mintlify for zero-effort beauty. Starlight for best defaults among open-source options.
