Paw vs Swagger UI: What are the differences?
Introduction
When it comes to API development and documentation, both Paw and Swagger UI are popular tools used by developers. However, there are key differences between the two that set them apart in terms of features and functionality.
User Interface: Paw is a desktop application with a user-friendly interface that allows developers to easily design and test APIs. On the other hand, Swagger UI is a web-based tool that displays APIs in a visual, interactive format, making it easier for users to explore and test endpoints.
Authentication Support: Paw provides built-in support for various authentication methods such as OAuth, Basic Auth, and JWT tokens, allowing developers to easily secure their APIs. On the contrary, Swagger UI mainly focuses on documenting APIs and does not offer extensive support for authentication mechanisms.
Code Generation: Paw offers code generation capabilities that allow developers to generate client code in various programming languages based on their API specifications. In contrast, Swagger UI does not provide built-in code generation functionality, requiring developers to use third-party tools or libraries for this purpose.
Collaboration Features: Paw includes features for team collaboration such as shared environments and synchronization, allowing multiple developers to work on API projects simultaneously. Swagger UI, on the other hand, lacks built-in collaboration tools and is more suited for individual developers or small teams.
Customization Options: Paw offers a range of customization options for API requests and responses, allowing developers to tailor their API specifications to meet specific requirements. In comparison, Swagger UI has limited customization capabilities, primarily focusing on rendering API documentation in a standardized format.
Integration with Backend Services: Paw provides integrations with popular backend services and tools, allowing developers to streamline the process of testing and deploying APIs. In contrast, Swagger UI is primarily focused on API documentation and does not offer extensive integrations with backend services out of the box.
In Summary, Paw and Swagger UI differ in terms of user interface, authentication support, code generation, collaboration features, customization options, and integration with backend services, catering to different needs of developers in the API development and documentation space.
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 README.md 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.
