Which one is for you

Pick Fern if

  • Fits if you maintain an OpenAPI spec and want a hosted docs site at no cost to start
  • Works for small API teams that want an API explorer and a custom domain on the free plan

Look elsewhere if

  • Skip it if you need SSO or SCIM, which are Enterprise only
  • Tight if you outgrow 1 site, 1,000 pages or 10 members, as the next step is a sales quote
  • Not for you if you want to remove Fern branding or add custom CSS and JavaScript without Enterprise
  • Watch out: SDK pricing sits on a separate tab that this listing did not read

Pick ReadMe if

  • Fits if you ship an API and want an interactive reference for developers
  • Works for a team of one project and one version that can stay on Starter

Look elsewhere if

  • Pricey if you need more than one version, as Pro is $250 a month
  • Watch out: Ask AI is $150 a month and the Developer Dashboard $100, both on top of the plan
  • Tight if you stay free, with 1 project, 1 version and 7 days of metrics
  • Watch out: roles, audit logs, SAML and OAuth 2.0 are Enterprise only, with no published price

More comparisons

How this page was made

  • The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
  • The grades are our own, from each tool’s review or report card. The GPA is their average.
  • Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
  • The differences and the answers to the questions are worked out from those listings.
