The short version

  • Each has a real cost: Docsify pages are assembled by JavaScript at runtime, so search engines and crawlers that do not execute scripts see an empty shell, which makes it unsuitable for documentation that must be found through search.; Rollup slower than the Go and Rust bundlers that followed it, since it is written in JavaScript
  • They diverge on capability: Docsify covers No build step, Rollup covers Tree shaking.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Docsify

  • Pages are assembled by JavaScript at runtime, so search engines and crawlers that do not execute scripts see an empty shell, which makes it unsuitable for documentation that must be found through search.
  • Every page view fetches markdown files over the network and renders them client-side, so on slow connections the site is visibly slower than pre-generated HTML.
  • Full-text search is built in the browser from all your documents, and the index becomes slow to build and heavy to hold once a site grows past a few dozen pages.
  • There is no built-in versioning, so supporting several releases of a product means directory conventions and hand-maintained sidebars.
  • The plugin ecosystem is loaded through script tags with no dependency management, so plugins break silently against new core versions and there is no build to catch it.

Rollup

  • Slower than the Go and Rust bundlers that followed it, since it is written in JavaScript
  • Application concerns like dev servers and hot reloading are not its job, so app builds need Vite on top
  • Configuration for non-trivial applications gets verbose compared with tools that assume more

Answered from the vendors’ own pages

Docsify: Is Docsify bad for SEO?

Yes, by design. There is no static HTML for a crawler to read unless you add prerendering, which reintroduces the build step the tool exists to avoid. Choose a static generator if search traffic matters.

Rollup: Is Rollup free?

Yes, open source under the MIT licence.

Docsify: Does it need Node.js to run?

Only for the local preview command. The published site is static files served by any web server, including GitHub Pages.

Rollup: Rollup or webpack?

Rollup is the usual choice for libraries thanks to cleaner output and better tree shaking. webpack remains stronger for complex applications with heavy asset handling.

Docsify: How large a documentation set can it handle?

Comfortably a few dozen pages. Beyond that, client-side search and sidebar maintenance become the limiting factors rather than rendering speed.

Rollup: Do I need Rollup if I use Vite?

Not directly. Vite uses Rollup for production builds, so you already benefit from it.

Docsify: Can I add versioned documentation?

Not natively. The usual approach is a directory per version with its own sidebar, maintained manually.
