As answered by people managing Natural Docs and Sourcey Docs.
Sourcey Docs's answer:
Sourcey Docs brings hand-written Markdown guides and generated reference from OpenAPI, MCP, Doxygen, godoc and rustdoc into one static build. The output includes built-in search and llms.txt, so readers and documentation retrievers can use the same self-hosted site.
Sourcey Docs's answer:
Documentation authors, API teams and open-source maintainers who need to publish guides alongside API and code reference. It fits teams that want static output they can host themselves and rebuild in their existing CI flow.
Sourcey Docs's answer:
Choose Sourcey Docs when one build needs to combine Markdown guides with reference generated from OpenAPI, MCP, Doxygen, godoc and rustdoc. The result is searchable static HTML, with llms.txt and context exports, that you can host on your own infrastructure. It is free and open source under AGPL-3.0-only.
