The short version

  • Each has a real cost: Read the Docs build configuration is finicky, and build failures on dependency changes are a common frustration; ReadMe pricing is per project, so an organisation with several distinct APIs multiplies the monthly bill rather than adding seats, and the sensible workaround, merging unrelated APIs into one documentation project, distorts the information architecture to fit the invoice.
  • They diverge on capability: Read the Docs covers Build on commit, ReadMe covers OpenAPI reference.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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

ReadMe

  • Pricing is per project, so an organisation with several distinct APIs multiplies the monthly bill rather than adding seats, and the sensible workaround, merging unrelated APIs into one documentation project, distorts the information architecture to fit the invoice.
  • The metrics and personalisation features require your API to stream request logs to ReadMe, which means production request metadata leaves your infrastructure and needs a scrubbing layer plus a security review before anything is switched on.
  • Single sign-on and private documentation sit on the higher tier, so a company that only needs to gate partner documentation behind SAML pays a large step up for one control.
  • The platform is built for describing REST APIs, and long-form product manuals, internal knowledge bases or non-OpenAPI protocols fit it badly, so most customers end up running a second documentation tool alongside it.
  • Theming is bounded by ReadMe templates and limited custom CSS, so a documentation site that must match a strongly designed marketing site will not get there without compromise.
  • Content uses ReadMe-specific Markdown extensions and platform features, so migrating away is an export plus a rewrite rather than moving a folder of Markdown files.

Answered from the vendors’ own pages

Read the Docs: Is Read the Docs free?

Free for open-source public projects. Private documentation requires a paid business plan.

ReadMe: Is ReadMe priced per user?

No. It is priced per project, meaning per documented API. Team size does not change the bill, and a second API generally does.

Read the Docs: What does it build from?

Most commonly Sphinx or MkDocs sources kept in your repository.

ReadMe: Do I have to send my API logs to ReadMe?

Only for metrics and personalised documentation. The reference, guides and playground work without it, but the features that most distinguish the product are the ones that need the log stream.

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.

ReadMe: Can I keep documentation in Git?

Yes. The rdme command line tool synchronises Markdown and OpenAPI files from a repository, so documentation can ship in the same pull request as the code.

ReadMe: Can I self-host it?

No. ReadMe is a hosted product only, so buyers with a hard on-premises requirement need a different platform.
