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.; Sphinx reStructuredText is harder to write than Markdown and puts off contributors, though MyST now allows Markdown
- They diverge on capability: Docsify covers No build step, Sphinx covers Cross-references.

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.
Sphinx
- reStructuredText is harder to write than Markdown and puts off contributors, though MyST now allows Markdown
- Configuration is complex and the default output is dated-looking without theme work
- Build times on large documentation sets are slow
- Heavier than the problem for a small project that only needs a few pages

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.
Sphinx: Is Sphinx free?
Yes, open source under the BSD 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.
Sphinx: Do I have to write reStructuredText?
Not any more. The MyST extension allows Markdown, though reStructuredText remains the native format and most examples use it.
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.
Sphinx: Why do large projects choose Sphinx?
Automatic cross-referencing and API extraction from docstrings, which lighter generators do not provide.
Docsify: Can I add versioned documentation?
Not natively. The usual approach is a directory per version with its own sidebar, maintained manually.
