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 It excels in modernizing outdated infrastructures effectively.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.

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

"The speed of development of production, especially in specific environments like IBM mainframes, has been valuable."

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

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

"Without OpenLegacy, it would take us several months to create the same services."

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

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

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

More OpenLegacy pros

"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."

"Since I started using SwaggerHub, it has had a positive impact on our organization due to better collaboration between developers and the quality assurance team, and it has reduced errors because of its automated validation."

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

"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."

"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 scalability is endless."

Cons

"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."

"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 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."

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

"Debugging and logging for programmers could be better."

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

"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."

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

"One of the most difficult things about SwaggerHub is the user interface and its usability, as it can feel quite complex and require too many clicks for simple actions."

"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."

"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."

"SwaggerHub's UI needs to be improved as it looks very old school."

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

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."
