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

"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."

"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."

"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."

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

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

"The user interface is very easy to learn and use, and it is a lightweight application."

"It is a scalable solution."

"The scalability is good."

"With Postman you can do automation. Automation has increased efficiency by more than 30% or 40%. Because the speed has increased, it's also possible for us to do in-sprint automation testing."

"Overall rating: Ten out of ten."

"It is a very stable solution."

"Postman is very user-friendly and accessible even for those with minimal experience."

"The tool is simple and easy."

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."

"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."

"If you have knowledge of JavaScript, the initial setup is easy and straightforward. If not, it may take some time to learn about JavaScript before starting the implementation."

"Could be more user friendly."

"We do the implementation of Postman and give support. We had to use two engineers for the implementation, one senior and one junior for the process."

"There needs to be more flexibility surrounding the testing of SOAP APIs."

"The request encryption could be one thing on which they can work a little bit. If we don't want to expose our production data but we still want to test our APIs on the production data, there should be a way to do that. It is not only with Postman. I think no tool in the market is doing that right now."

"We'd like to see videos or user-friendly reference documentation to help us figure out the solution or troubleshoot issues on our own."

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

"Reporting can be better. If you have bigger APIs, it takes time."

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 moderate pricing."

"This is an open source solution."

"This solution offers a free version."

"We are using the free version that is available."

"I rate the product's price a nine or ten on a scale of one to ten, where one is cheap, and ten is very expensive. Postman is an expensive tool for Turkey."

"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."

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

"We are currently using the free version, but we have plans to buy a license."
