These days the SaaS market is booming and it is going to go even further in the near future. There are many SaaS-based products being developed these days like Newsdata.io which is a news API with that you can get all the worldwide news data in a few clicks, now you don’t need to visit each and every news website to scrape their data.

This is the power of Saas-based products. People are creating web and mobile applications by using these SaaS products. For every API product that you build you need to have a documentation page for your users to understand how they can use your API product effectively.

In this article we will go through the best API documentation tool there is in 2022 for your API

The primary source of information on how an API works are API documentation. An API Documentation Tool (ADT) is a program that allows you to create, manage, and publish API documentation. It allows you to describe your APIs and their resources in a consistent manner.

An API documentation tool can help you reduce the time it takes your developers to write and maintain API documentation, provide a common set of documentation that is used across all of your APIs, and provide a consistent user experience for users moving from one API to another.

It is a guidebook for developers that describes the purpose and benefits of APIs, as well as best practices for integrating them. In general, well-structured documentation should include detailed information about arguments, classes, return types, and functions.

Most developers and IT consultants will agree, however, that integrating API documentation into your API ecosystem is anything but simple, especially when dealing with complex systems. In this case, an API documentation tool is extremely useful. We assessed twenty-plus API documentation tools based on the following criteria.

  • Document auto-generation from API definition
  • Maintain multiple documentation versions
  • Automatic documentation update
  • Collaboration
  • Customization available

1. SwaggerHUB

SwaggerHub is well-liked by techies and software developers. This is without a doubt due to its ease of use, interactivity, being fully hosted, and a slew of other useful features. It is more than just a tool for documentation. To put things into perspective, it supports SmartBear, has an open-source API editor, and is an interactive documentation tool.

SwaggerHub is a powerful visual tool that enables API providers to create interactive documentation for their APIs, allowing them to see exactly how the contract will work before integrating it into any code.

The following are Swagger’s advantages and disadvantages.


  • It offers a free tier to independent developers and solopreneurs.
  • Even inexperienced users will find it simple to use.
  • SwaggerHub is capable of executing API calls from the documentation.
  • APIs can be deployed to AWS Lambda and AWS API Gateway.


  • When paid annually, the team plan costs $90 per month.
  • Issues with cloud microservices compatibility

2. ReDoc.ly

ReDocly is at the top of this list because it supports both OpenAPI v2 and OpenAPI v3. It is also extremely adaptable and customizable. Regardless of the mode selected, each end-user has complete control over its mobile responsiveness, color themes, fonts, and branding images.

The interface is simple and uncluttered. The platform has been designed with the goal of focusing on simplicity and functionality, which should entice users to use it on a regular basis without feeling overwhelmed or intimidated by too many features.

With this API documentation tool, users can also use a variety of extensions. This includes the URL of the project’s logo, links to code samples, and integration with a Github repository.

The API documentation tool, which is built with React JS, is available in both free and paid versions. It also includes a CLI that provides access to all Open API definitions.

Although it was designed for large corporations, it can also be used by individuals and small teams. In general, the benefits of ReDoc.ly are as follows:


  • Highly adaptable

3. Stoplight

For a design-focused developer, Spotlight is the way to go. Spotlight’s built-in features make it simple to document your API. With automatic updates, accurate API documentation can be generated in a timely manner without the need for manual updating! Spotlight also saves you time on the time-consuming task of updating and maintaining documentation for each API change.

The API documentation builder in Postman makes it simple to create interactive and machine-readable API documentation. Postman enables developers to quickly build documentation for new or existing APIs by automatically pulling in sample requests, headers, and code snippets. Postman simplifies the publication of documentation by providing dynamic examples and machine-readable instructions.


  • Machine-readable comments allow for proper communication.
  • All API documents are automatically updated.


  • Complicated user interface
  • The learning curve is steep.

6. LucyBot DocGen
