  Postman is an API platform for designing and building APIs. Postman's API Documentation Tool helps you generate, edit, and publish your docs. Since Postman has one of the largest developer communities out there, it makes sense to choose Postman's API Documentation Tool if you're already integrated within their ecosystem.

• swagger-ui

  142 26,451 9.7 JavaScript

  Swagger UI is a collection of HTML, JavaScript, and CSS assets that dynamically generate beautiful documentation from a Swagger-compliant API.

  

  Swagger is a set of open source tools that help you design and build an API, which you define using an OpenAPI Specification (OAS). In particular, Swagger UI is a tool that takes your OAS and automatically generates documentation for your API in an interactive HTML page.

• github-action

  6 41 6.3 TypeScript

  GitHub action to deploy your API documentation on Bump (by bump-sh)

  

  Bump.sh is a tool that's swiftly gaining popularity as it combines many of the best features from the previous five entries in this roundup.

• apiDoc

  5 9,721 5.3 JavaScript

  Discontinued RESTful web API Documentation Generator.

  

  Compared to the first three tools, apiDoc takes a different approach towards generating documentation. Rather than rely on an API definition file like OAS, apiDoc is a package that allows you to add documentation directly into your source code through annotations. While there are third-party libraries that can create OAS files based on code annotations, having this built-in makes apiDoc slightly better if you want to control documentation through code instead of having a separate tool.
