SDE 2 at Virtusa
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.

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.
