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.

Automated testing optimizes API workflow and collaboration

Since I am using the free tier, one improvement would be to increase the number of requests you can send in a short time period. Currently, if I send 200-300 requests in a short period, Postman Enterprise requires a 30-second wait before sending another bundle of requests unless you upgrade to a higher tier. Secondly, Postman Enterprise sometimes takes several minutes to load the whole workspace. With 2,000-3,000 requests in a workspace, it can take a minute or two to load all requests. When creating a new workspace and moving requests between workspaces, depending on internet speed, it can take a longer period to copy those requests or workspace from one place to another.

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."

"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."

"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."

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

"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."

"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."

"One of the most valuable aspects of Postman is scalability. We can scale the collection and for the multiple repositories of the collections."

"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."

"The tool is simple and easy."

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

"It is stable and reliable."

"The variables part is good. We can easily define the variables and we don't have to manually do a change every time, it gets automatically updated."

"The product is easy to implement."

"Overall rating: Ten out of ten."

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."

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

"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."

"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."

"Debugging and logging for programmers could be better."

"Postman needs more advanced data-driven testing."

"UI testing needs to be added to the solution."

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

"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."

"Integration should be improved with our continuation system because we use Azure DevOps separately."

"Postman could be improved by providing options for performance testing of APIs."

"We cannot see transaction times in the product."

"I live in Turkey, so for me, the value of dollar currency is high...Postman can change its pricing policy and decrease the prices for Turkey."

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."

"We are using its free version."

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

"I use the tool's free version."

"This is an open source solution."

"We do not pay any money for Postman."

"This solution offers a free version."

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

"It is free."
