What it does
ReadMe is a hosted platform for API references, guides, changelogs, and developer-facing documentation. Uploading an OpenAPI file or URL generates interactive endpoint documentation with request and response examples and an API explorer. Teams can add conceptual guides, customize the documentation site, sync content with Git, and use branches for review. The service also documents API access for managing projects, so it supports both publishing APIs and integrating documentation into development workflows.
Start with an API specification or an empty documentation project
ReadMe's quickstart begins by creating a project and uploading an OpenAPI file or URL. The service validates the specification and builds a reference page with endpoint details and an interactive explorer. A team can then write a getting-started guide in the editor, add authentication instructions and examples, and preview the published docs. If no specification exists yet, the quickstart says to skip the upload and add it later.
For ongoing changes, ReadMe supports GitHub and GitLab workflows, branches, pull-request review, and local preview through its CLI. Its API V2 can also manage documentation programmatically. These options make it useful when API docs need to stay close to source changes, but the initial content still needs a valid API description or carefully authored guides.
The Starter plan is free and includes one project, while Pro and Enterprise add collaboration, access controls, and other capabilities. The pricing page also lists API and documentation features by tier. No account, project, API spec, or live endpoint was created or tested for this listing.
Strengths
- An uploaded OpenAPI definition generates interactive endpoint references with examples and an API explorer.
- Guides, references, changelogs, and Git-based review can be maintained in one developer documentation hub.
- The product documents both a CLI and API V2 for previewing or managing documentation programmatically.
Watch out for
- The free Starter tier is limited to one project and one published version; additional collaboration and controls require higher tiers.
Best for
- API teams publishing interactive reference pages alongside authentication guides and tutorials.
- Organizations that review documentation changes through Git branches and pull requests.
- Developers who want an API documentation platform with a free single-project starting tier.
