Most of our use cases are for Salesforce. So, the connectors for Salesforce have been really helpful. They've made development two times faster.

Mule ESB helps a lot with our microservice architecture that we're trying to build, and it is still our go-to technology when it comes to that, so it's very promising for us.

Mule ESB Cons review quotes

Mule ESB is more into the latest REST APIs, not much into the SOAP web services. Developing is all about web services and not easy with Mule.

From an improvement perspective, there should be fewer coding challenges for users in Mule ESB.
Archana Bhat - PeerSpot reviewer

One area that could be improved is the way that policies are propagated when APIs are moved from one environment to another. It's an issue, but when you develop and test the rest APIs in a lower environment and need to move them, there's a propagation process. This process moves certain aspects of the APIs, like the basic features. But when we move them, the policies don't always move with them. The policies should be able to move so we don't have to redo them manually. There are some APIs we use, but it's a bit tedious.

From my perspective, Mule ESB is lightweight, but it can be improved when it comes to the agility of the system.

From the product perspective, it was sometimes hard to manage the dependencies. When we had to add dependencies on a couple of different packages, it was sometimes confusing. It was hard to update them with Anypoint Studio, as well as with MuleSoft. There were challenges with that. So, that's one of the areas that could be improved.

I cannot say that installation with Kubernetes needs to be improved to be less tricky, but more information is needed from MuleSoft. They do not help much with Kubernetes, so we should have a person who is well-versed in Kubernetes to handle this.
Gowtham Thotapalli - PeerSpot reviewer

We would like the ability to use our own code. This would allow us to develop customizations with ease. Additionally, it would be nice to have more analytics or insights on the exchanged information between databases.

We would like to have a built-in logging framework in which we can do auditing.

MuleSoft is not so strong in method-based integration, so they're not so functional in that regard.
