The short version
- Each has a real cost: MkDocs no built-in versioning, which Docusaurus provides and documentation teams eventually need; Read the Docs build configuration is finicky, and build failures on dependency changes are a common frustration
- They diverge on capability: MkDocs covers Plain Markdown, Read the Docs covers Build on commit.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
MkDocs
- No built-in versioning, which Docusaurus provides and documentation teams eventually need
- Extending past the theme means writing Python plugins
- Markdown only, so embedding interactive components is not the model
Read the Docs
- Build configuration is finicky, and build failures on dependency changes are a common frustration
- Default themes are recognisable and dated, so sites look alike unless customised
- Private documentation requires a paid business plan
- Build times on large projects are slow enough to interrupt a review cycle

Answered from the vendors’ own pages
MkDocs: Is MkDocs free?
Yes, open source under the BSD licence. The Material theme has a free version and a paid Insiders edition.
Read the Docs: Is Read the Docs free?
Free for open-source public projects. Private documentation requires a paid business plan.
MkDocs: MkDocs or Docusaurus?
MkDocs is simpler and faster to adopt, especially for Python teams. Docusaurus offers versioning, internationalisation and React components, which matter once documentation grows.
Read the Docs: What does it build from?
Most commonly Sphinx or MkDocs sources kept in your repository.
MkDocs: Does MkDocs support versioned docs?
Not natively. Plugins such as mike add it, where Docusaurus includes versioning in core.
Read the Docs: How does versioning work?
It maps branches and tags to documentation versions, so several releases are served side by side without manual work.
