The biggest advantage is how simple the technology was.
I'd like to see OpenLegacy develop its low-code/no-code (LCNC) solutions. They've expanded somewhat their horizons for integration beyond mainframe CICS, which is their sweet spot. They have some tooling in that area, but it's not as good as it needs to be. OpenLegacy handles the bread-and-butter TP monitoring stuff, but I am working for one of the six banks in the United States still using the Hogan mainframe, which has a slightly proprietary mechanism. But OpenLegacy currently doesn't have a connector for Hogan. So it would help if they could build one. That would appeal to financial institutions that still use Hogan, like US Bank, Wells Fargo, KeyBank, and Vanguard.

Has streamlined API documentation and integration workflows across cross-functional teams
Documenting SwaggerHub has a standard and consistent structure of API definitions, and it automatically generates interactive documentation which helps the developers to understand everything. There are certain areas where SwaggerHub can go beyond here as formatting options for documentation pages are restricted, and the import and export options of API collections are complex in SwaggerHub. It provides various collaboration tools where we can work and do it. The strong validation against the API maintains conformity and reduces errors. That part is very great in SwaggerHub. Overall, scalability and stability-wise, it varies high compared to the competitors, but there are still certain areas where competitors are providing various customizations. SwaggerHub can understand those aspects and implement them as well. The complex import and export of API calls and collaborations can be challenging in SwaggerHub. If they can make it easier for us, that would be great. Their performance is degraded if there is too much load on the API. The customization and doc formatting options for documentation pages are restricted in SwaggerHub. A few of my teammates have complained that they find the UI unintuitive where it requires multiple clicks for simple tasks. SwaggerHub is a great tool, but these limitations can be addressed to make things better and easier.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Using OpenLegacy, the exposure of services is far easier and quicker. In many cases, exposure of services requires just a few clicks and takes only minutes. In very complex cases, it still only takes half a day. Without OpenLegacy, it would take us several months to create the same services."
"Without OpenLegacy, it would take us several months to create the same services."
"OpenLegacy produces a war file which includes everything you need to deploy a Tomcat server."
"The biggest advantage of OpenLegacy was how simple the technology was, and we were able to build out the OpenLegacy parts very quickly, putting together a couple hundred APIs in six months."
"It is possible to solve larger legacy API issues on an enterprise level with this product."
"The speed of development of production, especially in specific environments like IBM mainframes, has been valuable."
"OpenLegacy opens the door to connect modern web products to our old legacy system."
"The biggest advantage of OpenLegacy was how simple the technology was. We were able to build out the OpenLegacy parts very quickly. We put together a couple hundred APIs in six months."
"I rate the solution's stability a ten out of ten."
"One of the best features of SwaggerHub is how it allows me to create APIs and control the evolution of APIs within an organization."
"The best feature that SwaggerHub offers is the collaboration capability that helps us the most across all of our teams, as we have a single API infrastructure but several teams working in different areas of these APIs."
"The most valuable features are the collaboration between multiple teams and the control and distribution of specifications."
"The tool's most valuable feature is licensing."
"The most valuable features are the collaboration between multiple teams and the control and distribution of specifications."
"Normally, they publish their APIs on SwaggerHub for seamless integration with SmartBear and ReadyAPI, which allows us to perform detailed end-to-end automation testing."
"The scalability is endless."
 

Cons

"Debugging and logging for programmers could be better."
"Debugging and logging for programmers could be better."
"The pricing of the solution could be more flexible and allow for once-off payment versus annual licensing. This would be more appealing to companies in Latin America."
"They've expanded somewhat their horizons for integration beyond mainframe CICS, which is their sweet spot. They have some tooling in that area, but it's not as good as it needs to be."
"Customer support for the product is slow and not very good. It makes using the product difficult if you need help quickly."
"The pricing of the solution could be more flexible and allow for once-off payment versus annual licensing."
"I would like to see SSL out-of-the-box. OpenLegacy certainly does SSL, but it was not the default for our use case. We are currently working with OpenLegacy to cross the SSL bridge and suspect that most users will want to do the same."
"We would also be more than happy if the product had the option to work in the opposite direction – the ability to consume REST/SOW services in the outer world from the mainframe."
"More integration and usability with the cloud microservices would be nice."
"We have to use additional tools to test APIs."
"It could be more intuitive compared to one of its competitors."
"Some areas of SwaggerHub that could be improved include the interface between the code editor and the visual editor, the integration with private APIs, which currently requires an upgraded account."
"SwaggerHub could be improved with better integration for tools."
"The customization and doc formatting options for documentation pages are restricted in SwaggerHub."
"The scalability aspect of SwaggerHub can be improved. It becomes a bit unreliable when the load is increased and isn't up to par with expectations for scalability."
"The review process should be improved. There seem to be some gaps, at least for us, for the editing part because we would like to have a full request review mechanism."
 

Pricing and Cost Advice

"The pricing of the solution could be more flexible and allow for once-off payment versus annual licensing. This would be more appealing to companies in Latin America."
"The tool is cheap."
"It has a yearly subscription, but I am not sure."

SwaggerHub can be improved since the API testing features are limited compared to Postman, and it is somewhat expensive for small teams as paid plans cost a lot.
What is your primary use case for SwaggerHub?
My main use case for SwaggerHub is to design and review API specifications, as I test endpoints with the help of Swagger UI, validate the request and the response schemas, and share the API documen...

Before using SwaggerHub, I advise having basic API knowledge, as those with API knowledge can easily use SwaggerHub. I would rate this review an eight out of ten.
