• redoc

  35 22,515 7.9 TypeScript

  📘 OpenAPI/Swagger-generated API Reference Documentation

  

ReDoc is a tool that's similar to Swagger UI. It also takes an OAS and renders an interactive HTML page with full API documentation details; however, it has a notable difference.

• Newman

  241 6,718 7.5 JavaScript

  Newman is a command-line collection runner for Postman

  

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

  131 25,507 9.8 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 38 6.6 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

  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.
