Docup vs Docusaurus

Docusaurus is a site generator. You write the content in MDX, customise the site with React, and deploy the static files somewhere. Docup writes the content from your GitHub repository and hosts the site, so there is nothing to build or deploy.

What we say about Docusaurus comes from docusaurus.io on November 5, 2026. It can change, so check the site for the current details.

• Docs and blog posts written in MDX, built into static HTML, with React components you can embed in Markdown.
• Documentation versioning, so users on older releases get matching docs.
• Built-in internationalization, and support for Algolia search.
• The site lists Meta Platforms in its footer and links to the facebook/docusaurus repository. It describes no hosting service: you deploy the output yourself, for example to a static host.

• You want a first draft of the docs written from the code, not a blank site to fill.
• You do not want to maintain a build, a theme and a deployment.
• You want pages to follow the code: after each push only the affected pages are updated, and your edits are never overwritten.
• You want search, dark mode, an Ask AI box, llms.txt and markdown copies of every page without setting them up.

• You want full control of design and behaviour, with custom React components and plugins.
• You need versioned documentation for several releases at once, or built-in translation workflows.
• You want the docs to live as files in your repository and be built by your own CI.
