The short version
- Each has a real cost: GitBook hosted, so you do not own the rendering pipeline and are subject to platform changes; Sphinx reStructuredText is harder to write than Markdown and puts off contributors, though MyST now allows Markdown
- They diverge on capability: GitBook covers Two-way Git sync, Sphinx covers Cross-references.
Where they differ

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
GitBook
- Hosted, so you do not own the rendering pipeline and are subject to platform changes
- Git sync is powerful but conflicts between browser and repository edits are confusing to resolve
- Pricing scales per user, which gets expensive where many people contribute occasionally
- Less customisable than a static site generator you control end to end
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
GitBook: Is GitBook free?
There is a free tier for public documentation, with paid team plans above it. Check current rates with the vendor.
Sphinx: Is Sphinx free?
Yes, open source under the BSD licence.
GitBook: How does Git sync work?
Changes made in the browser commit to the connected repository, and commits to the repository appear in GitBook, so both editing routes stay in step.
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.
GitBook: GitBook or Docusaurus?
GitBook is hosted and lets non-technical people write directly. Docusaurus is free and fully controllable but assumes contributors work in a repository.
Sphinx: Why do large projects choose Sphinx?
Automatic cross-referencing and API extraction from docstrings, which lighter generators do not provide.
