Provides great UI to understand your API **Rating:** 5.0/5.0 stars **Reviewed by:** Michael S. | Embedded Software Engineering Intern, Enterprise (> 1000 emp.) **Reviewed Date:** June 24, 2019 **What do you like best about Swagger UI?** The Swagger UI is a great tool that allows you to easily see which endpoints are performing what actions. It also allows you to view the objects that your API uses, so it can double as database documentation. Both of these are presented very clearly and makes it really easy to show either new coworkers or interested parties a simple view of what is going on behind the scenes. Swagger also allows the documentation to be written in multiple formats (JSON and YAML), which makes it easy for everyone to edit. **What do you dislike about Swagger UI?** The only negative would be that the tool is very specific. The tool is designed for viewing the documentation of an API, and doesn't do much else. However, Swagger CodeGen and Swagger Editor offer more functionality that expands the API. **Recommendations to others considering Swagger UI:** Swagger UI is a great visual tool used in conjuction with the Swagger Editor that allows you to easily document your API and understand what is going on, from the REST endpoints to the actual objects your sending back. **What problems is Swagger UI solving and how is that benefiting you?** Overall, we have used the Swagger Editor mainly for documenting the API and the Swagger UI to clearly see what is going on. We haven't expanded much beyond that, but it works perfectly for what we are trying to do. ## Swagger UI Discussions - [What is Swagger software development?](https://www.g2.com/discussions/what-is-swagger-software-development) - 1 upvote - [What is the difference between swagger UI and Swagger editor?](https://www.g2.com/discussions/what-is-the-difference-between-swagger-ui-and-swagger-editor) - 1 upvote - [What is Swagger and why it is used?](https://www.g2.com/discussions/what-is-swagger-and-why-it-is-used) - 1 upvote - [What is swagger UI used for?](https://www.g2.com/discussions/what-is-swagger-ui-used-for) - [View Swagger UI pricing details and edition comparison](https://www.g2.com/products/swagger-ui/reviews?page=2§ion=pricing&secure%5Bexpires_at%5D=2026-07-17+21%3A16%3A01+-0500&secure%5Bsession_id%5D=8133ecdd-601a-4379-9e63-92fdb3696792&secure%5Btoken%5D=5a76032f504b9944444f414044e5f1aa4ddb9d76cb8d9991f3feaaabbdd930b0&format=llm_user) ## Swagger UI Integrations - [npm](https://www.g2.com/products/npm/reviews) - [spring.io](https://www.g2.com/products/spring-io/reviews) ## Swagger UI Features **Customization** - SEO - API Contracts - Change Management **API Construction** - API Testing - Data Security - Orchestration - Scalability **Organization** - Respository - Third-Party Integration - Access Management **API Management** - Traffic Control - Logs/Documentation - API Monitoring - Monetization - Gateway **Data Integration** - App Integration - Data Transformation - Plugins ## Top Swagger UI Alternatives - [MuleSoft Anypoint Platform](https://www.g2.com/products/mulesoft-anypoint-platform/reviews) - 4.5/5.0 (655 reviews) - [Kong Konnect](https://www.g2.com/products/kong-inc-kong-konnect/reviews) - 4.4/5.0 (320 reviews) - [Postman](https://www.g2.com/products/postman/reviews) - 4.6/5.0 (1,748 reviews)
