Developer at a hospitality company with 1,001-5,000 employees
Offers strong integration capabilities and reliable features but needs pricing and scaling improvements
Many things are evolving with the AI buzz in the market. What I would like to see improved or enhanced in webMethods.io in the future is that since webMethods.io is already under IBM, I think IBM will introduce and integrate AI into it. Additionally, regarding what webMethods.io can improve is the license cost. Other cloud players are also providing the same kind of functionality, such as AWS and Azure. webMethods.io is being installed on-premises, but AWS is providing it directly in the cloud. When comparing the license cost and request per minute cost, webMethods.io needs to address that. There are many competitors in the market for this.

Manager, Integration Technical Delivery at United Delta
Middleware integration has become smoother and manages API lifecycles and scopes effectively
Regarding WSO2 API Manager, I have no drawbacks or areas for improvement. However, regarding the Micro Integrator, I had some issues while developing complex services because it was mainly designed to be used for simple services, not complex ones. While using complex services, I encountered some issues. I communicated this with WSO2, and they released other products that solved everything related to my concern. These products were released before my concern was raised. When I explored them, they were pretty good, and I did not see the same issues I had experienced. WSO2 is enhancing themselves, and their products are fine. The previous concern was about the previous product, so it is resolved now since there are new products available. I would like WSO2 to improve quality or response time in support, or both.
