Wrote up a comparison of 10 docs-as-code tools: free and commercial.
The short version: MkDocs if you want something running in an afternoon, Docusaurus if you need versioning, Antora if your docs are spread across multiple repos. For managed hosting, Read the Docs is the most mature option. Swimm is in a different category — it's less about publishing and more about keeping docs accurate as code changes.
Full breakdown is here
