API management has strengthened security and monitoring but still needs better support and tooling

There are areas of IBM API Connect that need to be improved. I want what Gravitee made, which is much better. Gravitee made many samples for different use cases. First of all, they made examples of use cases, codes, and what the module expects and what the module returns for multiple examples and use cases inside the development. I do not even have to go to the documentation website because everything is included inside the tool when I work on it. This is great, in fact. IBM API Connect should show examples. One other thing is the support. The support of IBM is in India. Every time I want to ask something, they say they need logs, they want this, they want that. Gravitee API asks me to explain the problem without asking a thousand times as if it is a request for a green card in the USA. Then they really explain quickly. IBM is a big company, so everything is standardized with the approach of "You do that, you do that, you request that. If you do not have that, you do not reply to the client." Clients want flexibility today, even if it is a huge company. A stressed client is a client that will want to change to other flexible solutions. When everything is fine, we do not care, but when there is stress and problems, that is when the customer of IBM evaluates the tool really. It is when there are problems. IBM makes a lot of efforts on sales and technical sales, and then that is it.

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.
