The short version
- Each has a real cost: Sphinx reStructuredText is harder to write than Markdown and puts off contributors, though MyST now allows Markdown; VitePress customising beyond the default theme options requires writing Vue components, so a team with no Vue experience hits a wall at the first design request and cannot resolve it with configuration.
- They diverge on capability: Sphinx covers Cross-references, VitePress covers Vite dev server.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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
VitePress
- Customising beyond the default theme options requires writing Vue components, so a team with no Vue experience hits a wall at the first design request and cannot resolve it with configuration.
- There is no built in documentation versioning, so shipping docs for multiple released versions of a product means running separate builds or deploying separate sites and wiring the switcher yourself.
- Like every git based generator it offers no editing interface, so writers and support staff who spot an error cannot fix it without a developer workflow.
- The default local search builds its index in the browser at load time, so very large sites see a memory and startup cost on the reader side that Algolia would not impose.
- The plugin ecosystem is small compared with Docusaurus, so features such as blogging, tag pages or client side redirects are often hand built rather than installed.

Answered from the vendors’ own pages
Sphinx: Is Sphinx free?
Yes, open source under the BSD licence.
VitePress: Do I have to know Vue?
Not to write Markdown pages. Yes, as soon as you want to change the theme or add an interactive component.
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.
VitePress: Does it handle versioned documentation?
Not natively. You build and deploy each version separately and link between them.
Sphinx: Why do large projects choose Sphinx?
Automatic cross-referencing and API extraction from docstrings, which lighter generators do not provide.
VitePress: Is search free?
Yes, the built in local search is free and needs no service. Algolia DocSearch is supported if you prefer hosted search.
VitePress: How does it compare on build speed?
Development start time stays roughly flat as pages are added because Vite does not bundle in development. Production builds still scale with page count.
VitePress: Can non developers contribute?
Only through the git hosting web editor, which still means a commit and a pull request.
