Unified API gateway has reduced tool sprawl and has improved traffic control and observability
I give Gloo Platform a rating of 10 out of 10 because I genuinely appreciate it; it has all the features and requirements that I need. I give it a 10 because it fits my use case perfectly, enabling me to achieve my objectives, and I genuinely appreciate the Gloo Platform community and the people there. Regarding Gloo Platform's AI capabilities, I find them beneficial because they recently added agentic features and many AI capabilities that I find helpful. The accuracy and reliability of Gloo Platform's AI features is mostly consistent, although sometimes it does experience hallucinations. If you need a solution that provides management for your APIs along with features such as rate limiting, mTLS, and other functionalities, I would recommend Gloo Platform; it is truly excellent. I rated this review 10 out of 10.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Gloo Platform's features are optimal for my use case because I have numerous applications and microservices running, requiring rate limiting and traffic management integrated into one platform, which proves very beneficial."
"You don't need many frameworks or other things to run Glue."
"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."
"Without OpenLegacy, it would take us several months to create the same services."
"OpenLegacy opens the door to connect modern web products to our old legacy system."
"It is possible to solve larger legacy API issues on an enterprise level with this product."
"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."
"Using mainframe programs (not screens), the OpenLegacy services do not require any changes by the mainframe programmers, thus reducing development cycles."
"OpenLegacy produces a war file which includes everything you need to deploy a Tomcat server."
"The product has helped our business by allowing us to become more efficient in data handling."
 

Cons

"I sometimes face issues with integration."
"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."
"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."
