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.

Easy to deploy APIs and easy to manage CORS configuration
I have used WSO2 Store and WSO2 API Manager at the architecture level. I worked on two versions, namely WSO2 API Manager 2.6.0 and 5.7.0. I have also worked with WSO2 Identity Server versions 5.7 and 5.11. There are certain things that Apigee handles better than WSO2 API Manager. The user interface of WSO2 API Manager is much easier than that of Apigee. The scope of flexibility was much greater in Apigee. In WSO2 API Manager, we had little flexibility and were restricted to a specific software or tool. On the other hand, we had the scope of customization in Apigee.

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."
"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."
"Opens the door to connect modern web products to an old legacy system."
"OpenLegacy produces a war file which includes everything you need to deploy a Tomcat server."
"It is possible to connect a service to a mainframe program or back transaction in a matter of minutes or hours at the most."
"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."
"The documentation is good."
"WSO2 API Manager is easy to use."
"The solution is open-source."
"It's a good product."
"A complete integration suite and a good platform."
"Most of the time, we need to install a plug-in without having any lapse in services or restarting the application. The WSO2 platform can do all deployments without any downtime."
"Based on the information I have, the solution's most valuable feature is its capability of implementing custom solutions."
"This is a flexible and versatile API management solution that has the power to integrate with more than just API."

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."
"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."
"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."
"Debugging and logging for programmers could be better."
"WSO2 API Manager could improve the API approval system."
"I can say that user management is not really flexible. So, if I want to create 1,000 store users, I can't do it as a publisher. You have to register as a store user using the store URL."
"The price and the complexities attached to the solution are two areas of concern where improvements are required."
"I would improve the product documentation. There are some gaps, and it can be difficult to find the proper documentation for the product if you need to solve something."
"From a product perspective, the first thing is that although the documentation provided by WSO2 is good, it could be much better. We're in the middle of a complex migration, moving away from VMs to Kubernetes with the latest version of WSO2 and good documentation is essential to us right now."
"Integration is an area that needs to be improved."
"The technical support must be improved."
"WSO2 API Manager can be improved a lot relating to usability"

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."
"There is a subscription-based pricing structure and also the open-sourced version available."
"My previous company paid about 1.2 million dollars, and my current company pays about 300k. Both companies are at the enterprise level."
"The challenge is the increasing pricing, which has led some customers to consider alternatives, like using Spring Boot solutions instead. The rising costs, especially as cores and usage increase, have been a concern, prompting some to migrate to other products."
"We use the open-source version of WSO2 API Manager, there is no cost."
"We have not opted for the paid version of WSO2 but we have implemented the free and open source WSO2 software to a great extent and it is working as per our expectation."
"WSO2 API Manager is a low-cost solution. It is one of the most affordable solutions."
"It's not expensive, but it could be cheaper."
"WSO2 API Manager is quite an expensive tool. I rate the product's pricing a nine on a scale of one to ten, where one is low and ten is high."
