We Tried 5 Swagger Alternatives [In-Depth Comparison 2024]

Quick List of 5 Alternatives To Swagger

Here is a quick list of the 5 alternatives that I will compare today:

  1. PostmanBest known for its versatility (mobile, website, and API development tool).
  2. ReadMeBest for interactive API documentation.
  3. StoplightBest for designing, building, and documenting faster APIs.
  4. RedoclyBest API development tool with consulting services.
  5. Document360Best known for all-in-one documentation and robust tool.

Reasons To Consider An Alternative To Swagger

Here are some common reasons why one should consider Swagger API alternatives. They are as follows:

  • Cost: Swagger has an open source available for the developers to try out its features. But unfortunately, the free version doesn’t contain all the customized options for API development or other application programming interfaces. Additionally, the paid version might be expensive for some users. Hence, a low-budget developer must look for other sources with more customized options in the free version.
  • Ease of use: Some features of Swagger UI are complicated and require advanced programming language to operate. Hence, Swagger UI might not be suitable for non-technical developers. Therefore, they should look for a tool that is easier to use.
  • Performance Analysis: When working with big APIs, some users have complained that the Swagger UI can be slow and not well-responsive in time. Hence, a user should consider an alternative that can handle a more effective load if they’re working with a huge API.
  • Compatibility: Swagger UI is only associated with API development. Some users may also want other web services or mobile apps testing services, besides API development. Therefore, it’s necessary to find a tool that is compatible with every kind of project’s requirements of the developers.

Swagger UI vs Postman

Before comparing Swagger UI and Postman, one thing I must mention is that both tools are excellent when it comes to API testing progress. Additionally, both of the tools contain an open-source network (free version ) which allows the developers to make test scripts on it. But, Postman additionally offers website and mobile testing.

Furthermore, the interface of Postman is far more user-friendly than Swagger. Also, it allows you to collaborate with other developers which saves a lot of time in figuring out the debugs.

Swagger UI provides flexibility in choosing your own coding language whereas Postman requires JavaScript only to generate interface documents and perform the automation techniques.

But, Postman doesn’t require any coding for API development and therefore, if your focus is versatile such as API, mobile, and website, then Postman will be perfect in the list of Swagger competitors.


  • The interface is user-friendly.
  • It’s a comprehensive API testing tool with development and automation capabilities.
  • It allows collaboration with other developers.
  • it includes advanced and reliable integration techniques.
  • It also allows mobile and website application testing.


  • The free version has got limited features.
  • Learning JavaScript for automation will be time-consuming.

Our review of Postman

Though Postman is great for API development and automated testing only, if there’re any unwanted errors, the solution might be difficult. The amount of detailing on the error message is less which I found to be trouble being a non-technical developer.

Swagger UI vs ReadMe

In my intensive research, I’ve found negligible differences between Swagger UI and ReadMe. Both have a simple interface to operate with different API-related documentation.

ReadMe offers more customization options compared to Swagger UI and more advanced interactive documentation. But, the more advanced features come with a relatively high subscription cost, which is cheaper in the case of Swagger UI.

Therefore, according to your project’s requirement, for more advanced customizable options and Swagger alternatives, choose ReadMe, but one must remember the cost of the premium packages.

Hence, for lower-budget developers, I’ll suggest sticking to Swagger UI!


  • ReadMe is very easy to use.
  • It offers customized code templates for your projects.
  • The API analysis is robust.
  • Advanced integrations to improve the efficiency of the results.

Cons :

  • The premium packages of ReadMe are costly.

But most of the features are included in the premium packages, which can be really expensive for low-budget developers.

  • Numerous customized API features for development.
  • It also has a user-friendly interface.


  • The premium packages included with Stoplight are expensive.

Swagger UI vs Redocly

Firstly, Swagger UI is very easy to use with access to various programming languages for your API development. Additionally, it is an open-source API tool that enables many developers to work on their projects very smoothly.

But, on the other hand, the documentation feature of Swagger is limited and also doesn’t provide much support for design validations.

Whereas, Redolcy provides comprehensive API documentation features with advanced integrations and even consultancy services for business growth.

Swagger UI vs Document360

Both Swagger UI and Document360 are associated with the API documentation and the main tool is OpenAPI. But Swagger provides an open-source network for the developers to become habituated to the user-friendly interface.

On the other hand, Document360 is a platform specialized only to create or publish documentation, such as APIs. In case of interaction, Swagger UI provides a more interactive web interface with more options for customization.

The pricing list of Document360 is very high which lets the developers choose Swagger UI more. Lastly, the decision will be clearer based on the requirements of your project.


  • The interface is user-friendly.
  • It provides dedicated integrations for documentation.
  • 4 easy steps for API documentation.
  • It allows the developers to easily generate code samples.


  • The subscription packages are expensive.

Our review of Document360

According to my observation, I like how user-friendly the interface is and the features are exactly what I’m looking for in terms of documentation. Additionally, the API documentation is also top-notch.

As there’s no automation of API requests, documentation, or any other services, working on Document360 is time-consuming and also the server sometimes lacks communication with other users.

Frequently Asked Questions – FAQs

Is there something better than Swagger?

Swagger is best known for developing and creating many API management tools. But, for more integration techniques, ease of use, and greater availability of the project’s requirement, here are some better Swagger alternatives:

  • Postman
  • ReadMe
  • Stoplight
  • Redolcy
  • Document360
  • Insomnia
  • API Blueprint

Can Postman replace Swagger?

Yes! Though both Postman and Swagger are excellent choices for API documentation and testing, Postman provides a user-friendly interface and it doesn’t require additional coding knowledge to operate. Hence, I think Postman has the potential to become the perfect model for Swagger alternatives.

Is OpenAPI the same as Swagger?

Yes! Swagger is an open-source API testing tool that is built with the specification of OpenAPI. Eventually, this specific feature enables Swagger to build, design, document, and customize REST APIs.


To wrap up, if you want a tool that can account for mobile, website, and API testing, I will recommend Postman as a perfect tool for Swagger alternatives. Otherwise, if the demand only stays towards API documentation software testing and development, you can give Stoplight and Document360 a try.

Trust me! No matter which tool you choose, you won’t be disappointed!
