The short version
- Only MkDocs has a free tier, so it costs nothing to try first.
- Each has a real cost: Redocly only as useful as your commitment to OpenAPI; teams without a maintained spec get little from it; MkDocs no built-in versioning, which Docusaurus provides and documentation teams eventually need
- They diverge on capability: Redocly covers OpenAPI reference docs, MkDocs covers Plain Markdown.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Redocly
- Only as useful as your commitment to OpenAPI; teams without a maintained spec get little from it
- The portal and governance features are paid, while the open-source renderer covers only reference rendering
- Linting rules are another thing to configure and argue about before value appears
- Narrower than a general documentation platform, by design
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

Answered from the vendors’ own pages
Redocly: Is Redocly free?
The Redoc renderer and CLI are open source and free. The developer portal and governance features are paid, with pricing published on the vendor site.
MkDocs: Is MkDocs free?
Yes, open source under the BSD licence. The Material theme has a free version and a paid Insiders edition.
Redocly: What does the linter do?
It enforces rules on the OpenAPI spec itself in CI — missing descriptions, naming, examples — so a poor spec fails the build rather than becoming poor documentation.
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.
Redocly: Do I need OpenAPI to use it?
Effectively yes. Without a maintained specification there is little for it to work with.
MkDocs: Does MkDocs support versioned docs?
Not natively. Plugins such as mike add it, where Docusaurus includes versioning in core.
