Executive SummaryUpdated on Dec 17, 2024

OpenLegacy and SwaggerHub compete in the API management space. SwaggerHub seems to have the upper hand due to its feature-rich offerings.

Features: OpenLegacy focuses on seamless integration with legacy systems, enabling smooth digital transformation. It excels in modernizing outdated infrastructures effectively. SwaggerHub offers extensive design and documentation capabilities, which streamline the API development lifecycle. Its versatility in API design and management, with robust documentation tools, stands out by connecting various development stages efficiently.

Room for Improvement: OpenLegacy could benefit from enhancing its user interface to make it more intuitive. Increased support for non-legacy systems would broaden its scope. Further developing analytics features could provide deeper insights. SwaggerHub may improve by reducing its complexity for first-time users. Expanding integration capabilities would enhance its functionality. Improving user guides and tutorials could assist in better user onboarding.

Ease of Deployment and Customer Service: OpenLegacy provides a straightforward deployment process and excellent customer service, making implementation smoother. SwaggerHub offers sophisticated deployment tools but may present a steeper learning curve due to its comprehensive features. Once familiarized, users find its support in API lifecycle management advantageous.

Pricing and ROI: OpenLegacy offers competitive setup costs by delivering significant ROI through efficient legacy system integrations. Its value proposition balances costs with modernization benefits. SwaggerHub, though potentially more expensive upfront, justifies the expenditure with productivity enhancements, especially for teams involved in API design and collaboration. The choice hinges on whether a business prioritizes initial cost savings with OpenLegacy or the long-term productivity offered by SwaggerHub.

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.

Facilitating enterprise-wide API governance and management

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. The scalability also needs enhancement, as it becomes flaky under increased load. Additionally, the versioning management could be improved to be on par with source code management tools.

Quotes from Members

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

Pros

"OpenLegacy provides a way to go from the outside world to the legacy mainframe, to move the old standard application to a REST API application. New digital services can be created in a few clicks and this can be done easily by COBOL programmers."

"It is possible to solve larger legacy API issues on an enterprise level with this product."

"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."

"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. We were able to build out the OpenLegacy parts very quickly. We put together a couple hundred APIs in six months."

"It is possible to connect a service to a mainframe program or back transaction in a matter of minutes or hours at the most."

"Opens the door to connect modern web products to an old legacy system."

"Using mainframe programs (not screens), the OpenLegacy services do not require any changes by the mainframe programmers, thus reducing development cycles."

"The scalability is endless."

"The most valuable features are the collaboration between multiple teams and the control and distribution of specifications."

"It is a stable solution."

"One of the best features of SwaggerHub is how it allows me to create APIs and control the evolution of APIs within an organization."

"I rate the solution's stability a ten out of ten."

"The tool's most valuable feature is licensing."

"You can click & play and add the notation in a human-readable form. Spotlight is also very good in the graphical design of APIs."

"One of the best features of SwaggerHub is how it allows me to create APIs and control the evolution of APIs within an organization."

Cons

"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."

"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."

"Customer support for the product is slow and not very good. It makes using the product difficult if you need help quickly."

"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."

"Debugging and logging for programmers could be better."

"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."

"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."

"It could be more intuitive compared to one of its competitors."

"We have to use additional tools to test APIs."

"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. They support some comments, but it is really hard to manage those comments. We would like to use the full request. Therefore, we are now looking to integrate with repositories. It has integration with Bitbucket and GitHub, but we have some internal constraints, and we need to move some of the repositories to GitHub. Our source code is on-premise in Bitbucket, and it was a bit of a problem for us to integrate. Now we are transitioning our repositories to GitHub, and hopefully, we can enable the integration. This will probably solve the problem with the review and approval. Its customization should also be improved. There are limitations around the support for the developer portal. There should be more customization options for the website that you can use as a developer portal. Currently, it has only Swagger UI with minimal customization. You cannot actually add additional pages and documentation for explaining concepts and general things. That's why we have started to look around to see what other tools are doing. They should also allow tagging on the API. We would like to add some tagging on the API to reflect certain things. Currently, any metadata that you would like to have has to be a part of the spec. You cannot do anything else. It should also have support for Open API 3.1, which was released at the beginning of the year. It would be great to be able to switch to that."

"More integration and usability with the cloud microservices would be nice"

"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."

"SwaggerHub could be improved with better integration for tools."

"It has limited functionality...Unfortunately, some of its features are not what we need."

More SwaggerHub cons

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."
