The shift toward Astro-native documentation in 2026

Performance replaces heavy frameworks

Cloudflare migrated its developer documentation from Hugo to the Astro ecosystem to address scaling issues. The developers.cloudflare.com site outgrew the previous workflow for contributors and missed community-created features. Kim Jeske, Kian Newman-Hazel, and Kody Jackson explain that the Cloudflare content team scaled to deliver documentation alongside product launches, but the documentation site itself failed to scale. They adopted a "content like a product" strategy to provide world-class content that meets user needs. Starlight, the documentation theme for Astro, was a main reason for this migration due to its component overrides and plugin system.

Starlight has reached 8,400 GitHub stars as of April 2026. I see a clear trend where teams move to Starlight because it is faster than Docusaurus. Docusaurus is a React-based framework with 3 million weekly downloads. It provides versioning, internationalization, and a large plugin ecosystem. However, build performance can be a problem. Some users reported that Docusaurus builds on large sites can be very slow, and some builds even time out on GitHub Actions runners.

Starlight uses the islands architecture to keep the JavaScript payload small. Because Starlight uses the islands architecture, it sends only the necessary JavaScript to the client, which helps teams achieve high Lighthouse scores without the heavy payload of traditional React frameworks. This approach is one reason why 87% of Astro users intend to keep using it. Starlight also includes built-in search via Pagefind and dark mode support. It handles internationalization by using the locales and defaultLocale configuration. To set up multiple languages, you create a directory for each language in src/content/docs/, such as src/content/docs/ar/ for Arabic.

AI-ready docs drive platform selection

Documentation is no longer read only by humans. Large language models now read documentation to answer developer questions. Mintlify targets this need by auto-generating llms.txt and skill.md files. These files allow AI agents to index and understand product capabilities. Probes confirm that Docusaurus has no llms.txt or agent-oriented docs.md endpoint.

I find the pricing for Mintlify difficult for small teams. There is a large price jump between the free tier and the $450 monthly Pro plan. The Pro plan includes 10,000 credits, which covers 400 reader questions if each answer costs 25 credits. Documentation.AI is an alternative that costs $55 per month. Its plan provides 1,000 answers because each reader question costs only 10 credits. You can test the AI with a 14-day trial that has a 5,000 credit cap.

Mintlify also generates interactive API playgrounds from OpenAPI or AsyncAPI specifications. It writes code samples in 18 languages. The platform provides a REST API to trigger deployments, export analytics, and manage docs programmatically. This is useful for automation. Mintlify’s editor includes visual and source modes, live cursors, and drag-and-drop navigation. Mintlify also publishes an MCP server for AI tools. Fern is an alternative for teams that need bot-specific delivery for API documentation.

Does the automation of a managed platform outweigh the control of an open-source one?

Ownership versus managed convenience

The decision between Docusaurus and Mintlify depends on whether you want to host the infrastructure or outsource it. Docusaurus is a free, open-source framework. It is Meta-backed and powers documentation for projects like React Native, Jest, and Prettier. You can deploy it to any static host like Vercel or GitHub Pages. It provides total control over your data and your code. You can audit the source code and avoid vendor lock-in.

Mintlify is a managed platform. It handles hosting, search, and analytics. This saves engineering time for teams that want a polished site quickly. However, Mintlify keeps your content on its own infrastructure unless you purchase the Enterprise plan. This plan is the only way to get self-hosting or EU hosting.

I would skip Mintlify if your documentation relies on non-engineers. Mintlify requires a Git workflow through GitHub. This makes it hard for product managers or support leads to update content. GitBook serves these teams better because it provides a block-based visual editor and bidirectional Git sync.

Starlight is a good choice for teams that use Astro and want to avoid heavy JavaScript. It supports many languages, including Arabic, Chinese, and Vietnamese. It also provides automatic fallback content if a translation is missing. Docusaurus is the best free, open-source option. If you need an API developer portal where usage data per key matters, ReadMe is the better choice. Fern is a specialist tool that costs $150 a month and generates SDKs alongside documentation.
