Choosing a Documentation Framework
Choosing a Documentation Framework
Section titled “Choosing a Documentation Framework”Overview
Section titled “Overview”The documentation framework you choose determines your developer experience, site performance, and long-term maintainability. This section compares the most popular options and explains why we settled on Astro + Starlight.
Q: What are the main categories of documentation frameworks?
Section titled “Q: What are the main categories of documentation frameworks?”A: Documentation tools fall into four broad categories:
| Category | Examples | Pros | Cons |
|---|---|---|---|
| Static Site Generators (SSG) | Astro, Next.js, Hugo, Jekyll | Full control, fast, free hosting | Requires developer skills |
| Doc-Specific Frameworks | Starlight, Docusaurus, VitePress, MkDocs | Built-in doc features (sidebar, search, i18n) | Less flexible for non-doc pages |
| Hosted Platforms | GitBook, ReadMe, Notion Sites | Zero setup, WYSIWYG editing | Vendor lock-in, limited customization, paid |
| Wiki Systems | MediaWiki, BookStack | Collaborative editing | Dated UI, poor SEO, heavy |
Q: Why not Docusaurus or VitePress?
Section titled “Q: Why not Docusaurus or VitePress?”A: Both are excellent choices. Here’s a direct comparison:
| Feature | Starlight (Astro) | Docusaurus | VitePress |
|---|---|---|---|
| Framework | Astro (framework-agnostic) | React | Vue |
| Bundle Size | Minimal (ships zero JS by default) | Larger (React runtime) | Small (Vue runtime) |
| i18n | Built-in locale routing | Plugin-based | Manual |
| Search | Pagefind (built-in, local) | Algolia DocSearch (external) | VitePress search or MiniSearch |
| Content Format | Markdown + MDX | MDX only | Markdown + Vue |
| Performance | Excellent (static-first) | Good | Excellent |
| Ecosystem | Growing | Mature | Growing |
Our reasoning for choosing Starlight:
- Zero JavaScript by default: Starlight ships pure HTML/CSS, only loading JS for interactive components. This means faster page loads and better SEO.
- Framework agnostic: If you ever need interactive components, you can use React, Vue, Svelte, or any framework — no lock-in.
- Built-in i18n: Locale routing and language switching work out of the box.
- Content Collections: Astro’s typed content system catches schema errors at build time.
- Pagefind: Local, build-time search with no external service dependency.
Q: When should I choose a hosted platform instead?
Section titled “Q: When should I choose a hosted platform instead?”A: Hosted platforms (GitBook, ReadMe) make sense when:
- Your team has no web development skills
- You need collaborative editing by non-technical writers
- You’re willing to pay monthly for convenience
- You don’t need deep customization or custom build pipelines
For most technical teams, a self-hosted SSG approach gives you more control at lower cost.
Q: Can I migrate later if I choose the wrong framework?
Section titled “Q: Can I migrate later if I choose the wrong framework?”A: Yes, but the cost varies:
- Markdown-based frameworks (Starlight, VitePress, MkDocs): Migration is relatively easy since content is standard Markdown with frontmatter.
- MDX-heavy frameworks (Docusaurus): Requires converting JSX components back to standard Markdown.
- Hosted platforms: Export options vary; some lock your content in proprietary formats.
The safest bet is to keep your content in standard Markdown with clear frontmatter — then you can switch frameworks with minimal effort.
