Postman vs Wiki.js: What are the differences?


Postman and Wiki.js are two widely used tools in software development. While both tools are used to manage and organize information, they have distinct differences that set them apart. In this article, we will explore the key differences between Postman and Wiki.js.

  1. User Interface and Functionality: Postman primarily focuses on API testing and development. It offers a clean and intuitive user interface with features specifically designed for API related tasks such as creating requests, managing endpoints, and documenting APIs. On the other hand, Wiki.js is a versatile wiki software that allows users to create, edit, and organize documentation and knowledge base content. Its user interface is geared towards creating and managing articles, pages, and categories, making it a valuable tool for collaborative content creation.

  2. Collaboration and Access Control: Postman offers limited collaboration features. It allows users to share workspaces and collections with team members, but it lacks granular access control and permission settings that are crucial for larger teams. Wiki.js, on the other hand, provides extensive collaboration capabilities. It supports user roles, permissions, and access control at various levels, making it suitable for teams of all sizes. Users can define who can read, write, edit, and delete content, ensuring efficient collaboration and content management.

  3. Content Organization and Navigation: Postman organizes requests and endpoints as collections and folders, offering a straightforward hierarchy. While this structure is sufficient for API testing, it may not be ideal for organizing large amounts of textual content. Wiki.js, on the other hand, provides a more advanced content organization system. It allows users to create nested categories, hierarchies, and cross-link articles, enabling better structuring and navigation within the knowledge base.

  4. Search and Discoverability: Postman primarily focuses on API testing rather than content discovery. It offers a basic search functionality that allows users to search for collections and endpoints. However, Wiki.js puts a strong emphasis on search and discoverability. It provides advanced search capabilities, including full-text search, search filters, and search suggestions, making it easier for users to find specific content within the wiki.

  5. Customization and Extensions: Postman offers limited customization options. Users can customize the appearance of the application, but they have limited control over the functionality and features. On the other hand, Wiki.js allows extensive customization. Users can customize the look and feel of the wiki, add custom CSS or JavaScript, and even create custom plugins and extensions, providing flexibility to tailor the tool to specific requirements.

  6. Integration and Automation: Postman has robust integration capabilities and supports automation through the use of scripts and Newman, its command-line tool. It can be integrated with external tools, services, and Continuous Integration/Continuous Deployment (CI/CD) platforms. Wiki.js, although not primarily designed for automation, offers integration with various services and tools through its RESTful API. However, its automation capabilities are more limited compared to Postman.

In summary, Postman is a specialized tool for API testing and development with limited collaboration and customization options. On the other hand, Wiki.js is a versatile wiki software with extensive collaboration features, powerful search capabilities, and customization options. Depending on the requirements of the project, users can choose the tool that best suits their needs.

From a StackShare Community member: "I just started working for a start-up and we are in desperate need of better documentation for our API. Currently our API docs is in a file. We are evaluating Postman and Swagger UI. Since there are many options and I was wondering what other StackSharers would recommend?"

I use Postman because of the ease of team-management, using workspaces and teams, runner, collections, environment variables, test-scripts (post execution), variable management (pre and post execution), folders (inside collections, for better management of APIs), newman, easy-ci-integration (and probably a few more things that I am not able to recall right now).

I use Swagger UI because it's an easy tool for end-consumers to visualize and test our APIs. It focuses on that ! And it's directly embedded and delivered with the APIs. Postman's built-in tools aren't bad, but their main focus isn't the documentation and also, they are hosted outside the project.

I recommend Postman because it's easy to use with history option. Also, it has very great features like runner, collections, test scripts runners, defining environment variables and simple exporting and importing data.

Postman supports automation and organization in a way that Insomnia just doesn't. Admittedly, Insomnia makes it slightly easy to query the data that you get back (in a very MongoDB-esque query language) but Postman sets you up to develop the code that you would use in development/testing right in the editor.
