Executive SummaryUpdated on Jul 27, 2025

OpenLegacy and Postman Enterprise are competing products in the API integration category. Postman Enterprise seems to have the upper hand due to its comprehensive feature set and high user satisfaction.

Features: OpenLegacy offers fast transformation of legacy system functions into APIs, easing legacy modernization for businesses. It also supports IBM mainframes for rapid production development and simplifies integration processes with REST APIs. Postman Enterprise provides a comprehensive platform for API design, testing, and monitoring, supports automation and performance testing tools, and simplifies user interface interactions, enhancing the API lifecycle management.

Room for Improvement: OpenLegacy could enhance its open-source capabilities for greater flexibility and expand its feature set to support more diverse environments. Additionally, more extensive documentation could benefit new users. Postman Enterprise can improve on advanced configuration processes, enhance its support for various programming languages, and offer more intuitive onboarding for users unfamiliar with API management tools.

Ease of Deployment and Customer Service: OpenLegacy provides a straightforward deployment process with strong customer support, simplifying the integration with existing systems. Postman Enterprise also features an easy deployment model, supported by robust documentation and a responsive customer service team that benefits from wide community support and information sharing.

Pricing and ROI: OpenLegacy generally requires an upfront investment but provides high ROI for businesses reliant on legacy systems by lowering maintenance costs. Postman Enterprise can involve higher initial expenses due to its extensive API functionalities, yet it often results in quicker ROI through efficient development processes and reduced operational inefficiencies. While OpenLegacy offers value through specialization, Postman Enterprise delivers broader API lifecycle benefits.

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.

Solution simplifies web service testing with impressive speed and accessibility

It is very easy for me to use and I highly prefer it compared to SoapUI and other products for performing its job. It is more handy and faster. It has impacted us very nicely. Postman is used for free by us. I'm not sure if there might be a paid version for multiple users. It is a very good product used for development. It is easy to install, as well as to learn, particularly for new users, even if they are not developers. I taught my business analyst to use it. I just showed them once, and it was easy for them to understand. For example, I gave them the URL and request format and asked them to test independently. They were able to use it on their own and do their testing as well. It was a good experience, especially for generally smart people, like those we usually hire in our company. It is pretty easy to explain, and learning it is not complex.

Quotes from Members

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

Pros

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

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

"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 solve larger legacy API issues on an enterprise level with this product."

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

"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."

"The tool is simple and easy."

"The developers put the API in a common workspace which is a nice feature. It makes things much easier and faster to start testing."

"Postman lets you create, manage, and validate a suite of tests. It has several features to help you organize your test suite. You can also automate stuff with a lot of validations and assertions. Postman supports GraphQL, and you can do various kinds of calls."

"The solution is open-source and does the work required for day-to-day API testing activities."

"It is easy to install, as well as to learn, particularly for new users, even if they are not developers."

"One of the biggest advantages of Postman is its user-base approach."

"The most valuable feature is that JavaScript can be included as tests."

"I rate Postman as a ten out of ten."

Cons

"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."

"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."

"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."

"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."

"It would be beneficial to expand functionality with additional testing options."

"The management of endpoints' headers sometimes conflicts with APIs that require information in the body, leading to difficulties."

"The tool needs to have a reporting feature."

"During the development phase, you will face issues, but once it goes to production, you won't face such issues."

"Version management could be simplified."

"I don't think there is any need for comments on improvements."

"Initially, the setup is a little bit complex"

"I would like to see more integrations with other platforms."

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 solution has a licensing fee which might be prohibitive."

"Postman is an open-source product. It is free to download from Google."

"Postman is a free service."

"I am using the free option."

"It is free."

"I rate the price of Postman a four out of five."

"This solution offers a free version."

"We use the open-source version. They introduced a new licensing model where your company must subscribe to their services if you're using it for business purposes. However, I think they charge too much if you're only using the basic features. It limits what your organization can do if you're not a paying customer."
