ScrollUp is an open-source documentation framework based on Astro and released under the MIT License. It is designed to help developers and technical writers quickly build attractive, fast static documentation sites with MDX. It generates pure static HTML and does not require a server runtime, making it suitable for API, SDK, and CLI documentation, SaaS product help centers, and internal knowledge bases managed in Git repositories.
On the content side, ScrollUp supports mixing Markdown with JSX components. It includes built-in components such as Callout, Steps, Tabs, code blocks, cards, and file trees, reducing the need for extra plugin configuration. Search is powered by Orama: the index is generated at build time and runs in the browser, so no external service or API Key is required. For theming, it provides light, system, and dark modes, and emphasizes that the colors are not simply inverted. For internationalization, it includes UI chrome for en, fr, es, de, ja, hi, and more, while organizing content through content/docs/{locale}/.
ScrollUp only supports Astroβs static output mode. It can be deployed to Vercel, Netlify, Cloudflare Pages, GitHub Pages, and GitLab Pages, and it also explicitly supports self-hosting. Its CLI is mainly composed of npm scripts, including dev, build, preview, setup, new-page, validate, check-links, and check-freshness. These cover local development, builds, page scaffolding, link checking, and content freshness checks. Ecosystem integrations include Astro, @astrojs/mdx, Expressive Code, Orama, GitHub edit links, and a plugin system.
The main documentation does not mention commercial pricing, hosted plans, or enterprise support. Combined with the MIT License, it can be regarded as free and open source to use. Its strengths include a well-rounded feature set, flexible static deployment, no external search dependency, and plenty of documentation examples. Limitations include support for static output only; some configuration, such as section ordering, still requires code changes; the performance boundaries of client-side search for large documentation sets are not specified; and there is no visible support for versioned documentation, access control, or official commercial support.
ScrollUp is a good fit for development teams and technical writers familiar with Git, Node.js, and Astro/MDX workflows, especially teams that want to keep documentation inside code repositories and publish it through CI/CD. The main documentation does not provide information about access from China. Domains and dependencies such as GitHub, Vercel, Netlify, and Cloudflare may be affected by local network conditions in mainland China. Deploying to a self-owned server or a China-based static hosting provider can reduce access uncertainty. Alternatives include Docusaurus, VitePress, Astro Starlight, Nextra, and MkDocs Material.
