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 It excels in modernizing outdated infrastructures effectively.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.

VP, Chief Enterprise Integration Architect at a financial services firm with 10,001+ employees

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.

Software Architect at Waters Corporation

Centralized API documentation has supported versioned collaboration across our teams

We have tried automated code generation several times, and I think maybe some people are still using it somewhere, but it is not something that we do as a consolidated practice. At some point, we were missing some tagging of the APIs, and we could not do that. We asked the provider, but I do not believe they added that kind of support. However, we somehow gave up a bit because we are now in the process of moving to different platforms ourselves, so most likely we are not going to invest in improving this integration with SwaggerHub or how we are using it. We will just keep it going for the platform we are leaving, and then because our focus is in a different place, we are not looking to change or do other things. I am not using SwaggerHub's OpenAI management feature. We are not looking much at what they added new. We got some notification that they added things, but we have so many other things to do.

Quotes from Members

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

Pros

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

"OpenLegacy produces a war file which includes everything you need to deploy a Tomcat server."

"The product has helped our business by allowing us to become more efficient in data handling."

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

"OpenLegacy opens the door to connect modern web products to our old legacy system."

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

"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."

"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."

More OpenLegacy pros

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

"SwaggerHub is helping with team collaboration, as all the people now know the link, they just go there and get the information they need, and it is really a documentation tool for sharing documentation information about the API we support."

"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."

"SwaggerHub plays a crucial role in order to bring teams and automate things faster and also reduce the man-hours and increase the work efficiency."

"SwaggerHub has significantly improved how my organization designs, documents, and manages APIs, centralizing API management so that all API definitions are stored in one location, which makes it easy for stakeholders, developers, QA, DevOps, and products to access the latest version."

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

"It is a stable solution."

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

More SwaggerHub pros

Cons

"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."

"Debugging and logging for programmers could be better."

"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."

"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."

"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."

"In SwaggerHub, I appreciate that it is a powerful platform for API design and collaboration, but currently, the access control is somewhat limited."

"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 customization and doc formatting options for documentation pages are restricted in SwaggerHub."

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

"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."

"At some point, we were missing some tagging of the APIs, and we could not do that."

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

"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."

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."
