Room For Improvement

IBM B2B Integrator users desire better API integration, modern interfaces, simplified processes, cloud automation, and improved multilingual support.

Mule ESB requires user-friendly documentation, enhanced stability, better performance, scalability, exception handling, and improved analytics for broader adaptability.

Compared to other applications such as MuleSoft or Boomi, they have many cloud connectors and multiple connectors for integrating with Salesforce or other CRM or ERP applications, whereas here you may have to develop them, which is not native.

Points for improvement in Mule ESB definitely include enhancing the analytics capabilities because currently, they rely on external logging tools such as Splunk or ELK, which is lagging behind compared to other tools such as Workato that offer more analytical features.

Srinivas-Kanduri

Enterprise integrator at a tech vendor with 10,001+ employees

More information is needed from MuleSoft.

Setup Cost

IBM B2B Integrator is costly but offers flexible pricing with options for licenses and subscriptions based on usage.

Mule ESB's cost and flexible licensing appeal to enterprises, yet high fees lead smaller businesses to explore alternatives.

It tends to be very expensive because the IBM license model is oriented toward paying for the power of the machine where you install the platform.

They have their own language called DataWeave, which helps transform data and is efficient enough to handle any kind of transformation.

reviewer2704872

It is also reusable, meaning the same service can be used in multiple places simply by adding it, and this comes with the API-led architecture that makes integrations more secure and reliable.

Srinivas-Kanduri

Enterprise integrator at a tech vendor with 10,001+ employees

The best features of Mule ESB are that it's very robust and solid; I find that even our legacy systems go well with ESB.

Featured Reviews

General Manager Neverhack Spain at a tech vendor with 11-50 employees

Experience with robust integrator reveals strong performance and potential for interface updates

Based on my experience and my clients' feedback, there are a few points IBM can improve for IBM B2B Integrator. One of these is the graphical user interface. For several years, IBM has been promising to renew this interface, which has an ancient, old aesthetic, though it contains many functionalities. Creating a new interface would incur a very high internal cost with no new profitability for IBM. This is one of the points where customers say it feels like working in the 1990s with this interface. Another significant issue is that the platform is not multi-tenant. It's not possible to have different tenants in the cloud. This creates problems when trying to create SaaS offers based on IBM B2B Integrator, as there is the possibility that some workflow for a customer can be visible to another one. Since it's not multi-tenant, it's running on the same tenant of the platform. This is the main issue that the platform has.

Enterprise integrator at a tech vendor with 10,001+ employees

Integration architecture has enabled reliable multi-channel messaging and secure API management but now needs better analytics and simpler development

In my opinion, the real-time analytics part of Mule ESB is not up to the mark for the decision-making process. While there are some analytics features, they lack the standards needed for enterprise use. Compared to other analytics tools such as Power BI, MuleSoft falls short.Points for improvement in Mule ESB definitely include enhancing the analytics capabilities because currently, they rely on external logging tools such as Splunk or ELK, which is lagging behind compared to other tools such as Workato that offer more analytical features. Additionally, issues arise with AI-based use cases due to dependencies on Salesforce tools such as agent force, making development more complicated when it should be more independent. Developing AI-based agents without being tied to Salesforce applications could also enhance functionality.
