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.

Centralized collaboration has transformed API testing and documentation across multiple teams

In terms of improvement, the UI can sometimes feel heavy for larger collections in the workspaces. Additionally, performance may slow down with complex API projects, and pricing can be expensive for smaller teams. However, it is quite suitable for bigger teams. Other areas for improvement include better reporting and analytics dashboards, and more advanced native test environment features could enhance workflow, with smoother offline support and sync handling. Additionally, better performance for very large collections would be helpful, along with more intuitive navigation for enterprise-scale workspaces, stronger reporting analytics, easier management of permissions across large teams, and more flexible automation and testing report options would be beneficial. Small usability and performance improvements would make Postman Enterprise even more efficient for larger organizations. Postman Enterprise needs better performance optimization for large enterprises, more detailed analytics user reporting, improved API governance and audit visibility, simpler permissions and access control management, faster sync and loading times for larger collections, and more advanced built-in testing and reporting capabilities.

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."

"The biggest advantage of OpenLegacy was how simple the technology was, and we were able to build out the OpenLegacy parts very quickly, putting together a couple hundred APIs in six months."

"The speed of development of production, especially in specific environments like IBM mainframes, has been valuable."

"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 opens the door to connect modern web products to our 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."

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

"The product has helped our business by allowing us to become more efficient in data handling."

More OpenLegacy pros

"The initial setup of this solution is straightforward. Postman can be used as an extension in Google Chrome for those who do not wish to install it directly. Deployment took an hour and a half."

"Among the valuable features are data-driven automation response validation testing of the performance of APIs."

"The initial setup is simple."

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

"Postman offers great features, so I get a better opportunity to run bulk tasks through single command lines and single APIs, and we have an internal Postman AI tool, which helps improvise the code and analyze the quality if you find any errors."

"The interface and the different types of API methods you can use are the most valuable aspects of this solution."

"It is stable and reliable."

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

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."

"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."

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

"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."

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

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

"Version management could be simplified."

"The downside of using this solution is that you need to know JavaScript."

"It is not that easy to use and should have a more improved easy-to-use interface."

"Postman needs to improve its support for a lot of integrations."

"The reporting could be better. It should give you a detailed PDF report after you run a test."

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

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."

"The solution is open-source and free."

"I use the tool's free version."

"This tool is open-source and free to download and use."

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

"Postman is a free service."

"We are using its free version."

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