As a developer, you know that documenting your API is just as important as creating it. Proper documentation can help other developers understand how to use your API, reducing confusion and errors while promoting adoption. However, documenting an API can be time-consuming and tedious, and mistakes can easily slip through the cracks.
That's where an API documentation tool comes in. These tools help streamline the documentation process and ensure your API documentation is consistent, complete, and easy to use. With the right tool, you can save time, reduce errors, and improve the developer experience.
What is an API Documentation Tool?
API documentation is essential for developers to understand how to use an API effectively. It helps them to understand the API's capabilities, features, and constraints. An API documentation tool is a software application designed to generate documentation for an API automatically. It provides an organized and accessible way for developers to access information about the API, such as the API's endpoints, request and response parameters, error messages, and other relevant details.
The Vital Role of API Documentation Tools in Maximizing API Potential
API documentation tools provide several benefits. Firstly, they automate the process of generating documentation, saving developers time and effort. This frees up time for other important tasks and eliminates the risk of errors that can occur when documentation is manually created and updated. Secondly, API documentation tools ensure that the documentation is always accurate and up-to-date, which is particularly important in rapidly evolving development environments.
Finally, good documentation builds trust and credibility with developers, making it more likely that the API will be adopted and used effectively, leading to increased project or organizational success.
How to Choose the Right API Testing Tools
When choosing API testing tools, there are several factors to consider. Some of these factors include:
- Type of API - The API being tested will influence the choice of API testing tool. For example, RESTful APIs and SOAP APIs may require different testing tools.
- Features - The features offered by the API testing tool should align with the testing requirements of the application.
- Integration - The API testing tool should be able to integrate with other tools used in the development process, such as continuous integration and deployment tools.

SwaggerHub is a popular API documentation tool that leverages the core capabilities of Swagger. It offers great scalability and API version management, making it an ideal choice for larger development teams. SwaggerHub facilitates collaboration on API definition, allowing team members to work together on API designs quickly and efficiently. Additionally, it integrates with popular development tools such as GitHub.
- Utilizes the capabilities of core Swagger, which is familiar to many developers
- Excellent scalability and API version management features
- Facilitates collaboration on API definition for larger teams
One of the standout features of SwaggerHub is its familiarity with developers. Since Swagger is widely used and familiar to many, it's a tool that can be quickly adopted and implemented with minimal training. SwaggerHub provides the same functionality as open-source Swagger tools, with the added benefit of combining these tools into a single platform to manage your API's lifecycle.
- Conceptual documentation is not supported
- No new added documentation features beyond Swagger Editor and Swagger UI
- UI may require additional customization
One of the limitations of SwaggerHub is that it needs to support conceptual documentation, such as knowledge articles, use cases, and tutorials. All documentation is added in your API definition and only describes endpoints and fields. There is also no dedicated markdown editor, which may be a drawback for some users. Additionally, the UI may not be aesthetically pleasing, and extensive customization may require extending Swagger using ReactJs components.
Postman is a very popular tool for API testing and collaboration. It allows you to organize API requests into a logical structure and guides the user using API examples for authentication, getting started, tutorials, troubleshooting, and more. The structure of the published documentation mimics the structure of your collections. It is known for its web and desktop application that acts as an HTTP client for sending and receiving requests.
- Credentials are stored as variables and are populated in requests, making testing APIs very efficient.
- Updates automatically based on changes to API definition, reducing the need for manual updates.
- Easy sharing and collaboration, allowing for better team communication and workflow.
- Postman hosts your docs, making sharing documentation with internal teams and clients easy.
While Postman is most known for API testing, many overlook its documentation features. You can add descriptions to each API request and folder using either markdown or rich text within the app. When you are done documenting your collections, you can publish your documentation on the web. Postman hosts your publicly available documentation and provides a public URL that you can share with your internal team and clients.
- Extensive styling is not supported, limiting customization options for published documentation.
- The editor can be uncomfortable to use, especially for long articles.
- Supports only basic markdown, making it difficult to format documentation.
- Changing the table of content requires restructuring collections, making it difficult to make changes to the structure of the documentation.
- Lack of search, making it difficult to find specific documentation.
While Postman’s documentation features are limited, teams already using Postman can benefit from having documentation generated automatically from their collections. However, teams looking for more customization options and advanced authoring features may need to explore other documentation tools.
Stoplight is an all-in-one API design, development, and documentation platform that prioritizes standardization, quality control, and governance.

Stoplight Documentation is the primary product for managing API design and publishing documentation, while Stoplight Elements and Stoplight Dev Portal provide easy integration and customizable templates. The tool promotes seamless integration between conceptual and reference documentation through interactive "try-it" consoles and reference schemas from your API definition.
- Lack of Metrics in Stoplight
- Outdated Open-Source Projects
Stoplight does not offer a dashboard to view key metrics such as page views, search terms, ratings, or comments left by users. The lack of metrics is a significant disadvantage as it hinders users' ability to capture user behavior and motivation. Stoplight's open-source projects, Elements and Dev Portal, have not been updated in over a year and lack support. This lack of support may make these tools non-viable as a long-term business solution.
Readme is an enterprise-style platform designed to create interactive API hubs and optimize API usage. Its main goal is to enhance the developer experience by providing a feedback loop for quality improvement by combining API usage with documentation metrics. The standout feature of Readme is its API usage metrics. It allows for extensive documentation of API usage, and users can monitor successful and unsuccessful requests using the API Explorer. Troubleshooting errors is made easy by having access to users’ API logs.
- In-depth user and team management settings
- Integrations with popular tools like Slack
- Very attractive and stylized UI
- Future GraphQL support
Readme’s documentation metrics include top page views, page views by each user, popular search terms, and ratings left by users. Comments can provide insights into underperforming pages. Analyzing user behavior changes over time can help businesses determine who uses their API the most to uncover further sales opportunities, see if new or existing users’ accounts drive the most API usage, and troubleshoot errors.
- No interactive user guides
- Code samples are hard coded
- No link validation
- Unable to embed the Try-it-out console from reference docs into conceptual documentation for interactive tutorials and workflows
For code samples, Readme has “recipes” that are step-by-step walkthroughs for use cases, but they only allow for referencing one API endpoint per recipe. This limitation may not fully show the process of completing a task, which may entail sending requests to various endpoints. Additionally, You cannot easily manage the code samples since they are hard-coded and cannot be sourced from a repository. Readme provides no out-of-the-box link validation or integrations with third-party tools that manage to link. Since maintenance of links is a critical issue as documentation projects grow, using an external linking service not integrated with Readme may prove inefficient at best and detrimental to link quality at worst.
