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.

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

"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."

"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."

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

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

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

"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."

"What is most valuable for me is that we can create and share collections between the team members."

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

"Postman is useful for API testing."

"Postman uses the DRY framework of JavaScript and that framework is easy and a good way to put assertions on responses."

"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."

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

"It is a scalable solution."

"The scalability is good."

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."

"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."

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

"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."

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

"Postman does not have a check-in balance. Essentially what I mean by that is if there is something that is already configured on a particular device, it just overrides it without checking whether you really want to override it or not."

"The performance needs to be improved."

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

"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."

"Integration of the solution towards Bitbucket, BitHub, and CI pipelines is difficult."

"It would be better if we could integrate programming languages like .NET, Java, and JavaScript. It could also be more user-friendly."

"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."

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

"We do not pay any money for Postman."

"It is free."

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

"Postman is a free service."

"I am using the free option."

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

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