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."

"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."

"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."

"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."

"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."

"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."

"I recommend Postman for all business types."

"Postman allows you to incorporate and export the test cases we create. It enables me to share the test cases with my colleagues, so I don't have to copy them into an Excel sheet. Postman lets me export the dataset and share it with my team. They can use my test case for their testing."

"No coding required."

"It is stable and reliable."

"Postman is easy to use and enables us to test all possible API testing scenarios."

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

"This solution offers a free version."

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."

"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."

"The pricing should be adjusted for the Pro plan."

"One of the features that is missing in Postman is reporting; it's very basic."

"They should integrate the solution with one of the CRM solutions."

"If there is any way to have a record and playback feature through UI, as we do in Selenium and IDEs such as Eclipse, it would be great."

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

"I would like to see improvements in the maintenance of the scripts and their collections. It is really painful that the user cannot drag and drop. It was also painful to create the standard suite of operations for the product. I am not sure if this is improved in the tool’s latest versions. The maintenance of the complex scenarios prompted us to use the solution only for unit testing. In the future, we may switch to the k6 framework."

"We have previously used Tosca which allowed us to verify information using authentications. It would be useful if this was also possible using Postman. In a future release, Postman should connect to DB."

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

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."

"It is free."

"I use the tool's free version."

"The solution has moderate pricing."

"Postman is a free service."

"The solution's price is reasonable."

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

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

"This solution offers a free version."
