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

"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."

"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 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."

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

"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."

"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 solution is open-source."

"The product is easy to use."

"Functionality-wise, I like WSO2 API Manager - Publisher API and WSO2 Enterprise Service Bus."

"WSO2 API Manager's most valuable features are the simple interface that is easy to use and the APIs lifecycle."

"The solution is open source and easy to configure."

"Yes WSO2 API Manager is scalable"

"As far as I am aware this solution is the first API Publisher that allows you to create and publish API and to manage the API lifecycle."

"Based on the information I have, the solution's most valuable feature is its capability of implementing custom solutions."

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."

"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."

"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."

"WSO2 API Manager could improve the API approval system."

"The price and the complexities attached to the solution are two areas of concern where improvements are required."

"They don't have different URLs for administrators."

"WSO2 API Manager could increase their security compliance."

"We found WSO2 API Manager to be a bit complex."

"I think they could greatly improve the general UX with their solutions."

"From what I have experienced from the versions I have tried, they could improve on the multi-tenant environments to allow some kind of SSO single sign-on between tenant."

"The tool's commercial aspect could be improved. Pricing varies with partners, so selecting the appropriate pricing can be challenging."

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 use the open-source version — the free version."

"It is an open-source product."

"I am using the free version."

"We use the open-source version of WSO2 API Manager, there is no cost."

"There is a subscription-based pricing structure and also the open-sourced version available."

"For our projects, we found the pricing to be a little high."

"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."

"I think the other competitors that are providing the same solution are quite expensive. WSO2 API Manager is quite cheap."
