  6. Code Generation: Apidog generates front-end and back-end code based on the API and data model specifications.
  7. Team Collaboration: Apidog is designed for team collaboration. It synchronizes real-time updates on the API cloud and supports team/project/member permission management.


SwaggerHub is fundamentally a key documentation tool for APIs. Its main function is to provide a collaborative environment where developers can define API structures, create documentation, and generate client SDKs using OpenAPI specifications. Developers use SwaggerHub to develop API definitions collaboratively, with the tool providing an intuitive, real-time interface for defining APIs, describing their functionalities, and setting up their endpoints.

Main  Features of SwaggerHub:

  1. Easy Integration: It seamlessly integrates with Bitbucket, Github, and other tools.
  2. API Documentation: SwaggerHub supports documenting APIs using Swagger 2.0 or OpenAPI specifications.
  3. Version Control: It allows for the iteration through multiple versions of a definition privately before making a version publicly available.
  4. Code Auto-generation: SwaggerHub reduces effort in defining clients with its auto-generated code capability.


  1. Limited Testing: SwaggerHub needs to gain the ability to write test cases as Postman does.
  2. Limited Configuration: It doesn't support configuring and integrating different environment variables with third-party software.
  3. Limited Examples per Endpoint: Under the Swagger 2.0 standards, you can only provide one example for each endpoint, limiting its usefulness for complex scenarios.


Postman operates as an API client, offering developers a feature-rich environment for testing API endpoints. Developers use Postman to send requests to API endpoints and view the responses. It supports HTTP requests like GET, POST, DELETE, and PUT. It also has built-in features for setting up various parameters, headers, and body data. Postman's most notable feature is its ability to automate the process of API testing. Developers can write scripts to automate tests, which can be executed in bulk, saving time and effort in manual testing.

Key Features of Postman:

  1. Collaboration: Postman allows teams to work together on APIs.
  2. Monitoring and Testing: Postman enables users to monitor and test APIs.
  3. Mock Servers: Postman provides a feature to simulate API responses for testing.


  1. User Interface: Some users find the interface less intuitive than expected.
  2. Feature Complexity: The wealth of features in Postman can sometimes be overwhelming for new users.
  3. Collection Runner Limitation: Postman users contend that the free and basic plan's 25-run limit could be more reasonable, prompting calls for Postman to reconsider its changes.
How to Fix Postman Collection Limits for Free
There are several methods to fix Postman Collection Runner restrictions. However, creating your collection with Apidog has no limits and is free.
