Best for	Python API documentation	C/C++ codebases needing API docs
Who it's not for	Non-technical writers who want plain Markdown	Non-developers . it documents source code, not products
Privacy	Open-source project with public GitHub advisories; no active breach disclosures found, but vendor security page 404s.¹⁰	No known public vulnerabilities found in the sources reviewed.¹²
Support quality	Community-only; no evidence reviewed	No usable evidence retrieved
Public sentiment	Reddit threads actively weigh Sphinx against MkDocs for Python docs, with its power offset by a steeper authoring workflow.^⁵	No usable Doxygen reviews were retrieved . results were unrelated '404' content such as samplers, error pages, and SEO posts.
