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

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

"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."

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

"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 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."

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

"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 API testing features are valuable."

"We use it for REST API testing. Feature-wise, it is pretty lightweight. It is pretty fast, and we don't have to do a lot of things. We can just simply go and post our endpoint, and it gives different kinds of authorizations. We usually use authentication 2.0, which is the most common industry practice. So, it has the support for authorization through 2.0."

"We can test APIs. We know if they are functional or throwing any errors."

"It helps me to test APIs independently. It also supports hosting."

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

"The solution has a great user interface and collection of features."

"It is beneficial to have flexibility, especially with API chaining."

"The most valuable feature of Postman is the large libraries."

Cons

"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."

"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."

"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."

"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."

"One area that could be better is collection management."

"I have recently noticed that, for some reason, I am not able to import collections in JSON. It is weird because I was able to do it before. When you create a new collection and documentation, in tests, you usually have to click Save. If you don't click Save, your collections don't sync with other devices, which is something I don't like. It is not clear for the users in a shared workspace, and I usually forget to click Save and end up losing all the collections that I created. I create a lot of routes, and clicking Save all the time isn't efficient. Instead of clicking Save all the time, there should be an option to save everything in one go."

"The main improvement needed is better integration with test management and other tools to allow a common dashboard for all testing metrics and details."

"I have display issues in my Windows that need to be fixed."

"Postman quality assurance could improve when doing tests."

"The solution can be improved by providing detailed error logs including the line the error took place to make it easier to correct."

"An area that needs some improvement would be to allow multiple windows with different collections to be open at the same time."

"I would like to see advanced automation in reference to Postman."

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."

"I am using the free option."

"The solution has moderate pricing."

"Its price is moderate as compared to other competitors. The version that we are using is not open source, so it is not free."

"We do not pay any money for Postman."

"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."

"Postman is a free service."

"The solution is free for individuals, but for companies that use it across the organization, you have to pay per user."

"The solution has a licensing fee which might be prohibitive."
