Has API-led architecture and provides a unique, user-friendly, and scalable architecture for hosting APIs

There's room for improvement in multi-file transfer functionality. It's not convenient when using MuleSoft, and it should have better capability for handling large amounts of data. For example, applications like GoAnywhere can handle huge chunks of data, so the tool should also have something to facilitate that aspect of integration.

Decreases the development timeframe and costs

The main issue with the product is pricing. It uses core-based pricing for WSO2 Enterprise Integrator and API Manager. It would be best if you had APIM by default. It provides many connectors for easy integration with third-party systems. Often, customers decide to develop using open-source tools like Spring Boot if there aren't many connectors required to avoid increasing costs. They'll develop this way and then deploy using APIM, the bare minimum needed. It is mainly required for very complicated setups with many connectors. In the implementations I've seen, people often used open-source tools because there weren't many third-party systems involved—just their organization's own systems. From WSO2 Enterprise Integrator, I expect them to bring up more and more connectors in the future. That's the main expectation. Having more connectors in various areas will help us when discussing new requirements. I don't have any specific use case right now, so I can't name a particular connector. But, as new technologies emerge, the relevant connectors should be there for those. WSO2 Enterprise Integrator mainly helps with the integration part, which can be simplified only if you have relevant connectors for whatever you're doing.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The setup is straightforward."

"I am impressed with the product's connectors and scalability."

"I like that Mule ESB provides fast and good technical support."

"For complex cases, we employ the SSLi engine, whereas for simpler ones like healthcare or response data, such as EDI 270 or 271. We prefer to use an external XRT engine instead of handling it within the ESB for ease of management."

"The solution improved my company by modernizing the way we offer services and improving the user experience."

"The connectors help to connect with a variety of applications."

"The solution doesn't require much code writing and we can develop APIs very easily."

"The most powerful feature is DataWeave, which is a powerful language where data can be transformed from one form into another."

More Mule ESB pros

"It's a consolidated product. It works and it does its job pretty well."

"It was mostly easy to set up the product."

"The solution's technical support is very knowledgeable."

"Currently, I find the configuration part quite valuable, where you can easily configure things."

"The customer service executives are very responsive."

"The drag-and-drop features for connectors are very valuable."

"In my opinion, the most valuable aspect of this solution is its extensive range of adaptors and connectors. This feature holds significant importance and provides great value to users."

"The connectors have been the most impactful features for handling integrations. I can use these connectors when I need specific connectivity with a third party, like a core banking system in BFSI. I don't need to do all the development. I take the specific connector, put in the IP address and password, and it takes care of everything."

More WSO2 Enterprise Integrator pros

Cons

"I would like to see support for BPM in the next release of this solution."

"It's not easy to troubleshoot and we still can't make it work."

"Limitation on external subscribers to listen to the messages on the bus."

"In an upcoming release, I would like to see more additional concept for exception handling, batch processing, and increased integration with other application."

"The payment system needs improvement."

"Mule ESB isn't as secure as IBM. Financial companies go with IBM for that reason."

"The price of Mule ESB could improve."

"It should have some amount of logging."

More Mule ESB cons

"They should introduce better pricing for small companies."

"You cannot include the validation of XPath."

"The administration side is complex and could use significant improvements to enhance the solution's functionality."

"The main issue with the product is pricing. It uses core-based pricing for WSO2 Enterprise Integrator and API Manager. It would be best if you had APIM by default. It provides many connectors for easy integration with third-party systems."

"The customization can be a bit difficult."

"The server is very specific and it is very difficult to get experience with it."

"The integration capabilities need to be improved."

"WSO2 libraries are not mature enough. For example, if you want to integrate with Kafka using its Kafka library, it often has many bugs."

Pricing and Cost Advice

"Most of the challenges that I had with this solution were for smaller customers. There is not a good licensing model or pricing model. It is more expensive than other solutions, and that's the downside of MuleSoft. I had to be creative to be able to sell it to the business, but we did. This is something they have to work on because for large companies, it's affordable, but for small and medium businesses, it's very hard to sell."

"This product is cheaper than some offered by other vendors, although there is a problem because you have to pay for some third-party adapters."

"Regarding licensing and pricing, I find it somewhat flexible. They are more flexible with larger customers compared to small and medium ones, as their licensing model depends on ports and other factors. Large customers benefit from more flexibility in implementation and renewal compared to smaller ones."

"Plan your licensing model (cloud or on-premises or hybrid) that will allow seamless integration with new partners."

"Mule ESB is an expensive solution."

"The licensing is yearly, and there are additional fees for services."

"Mule ESB is a costly solution. We pay approximately $80,000 annually for the system. The cost of the number of instances, annual subscription, and cloud hosting services are expensive."

"This is expensive. In my next project, we had to go to other vendor."

More Mule ESB pricing and cost advice

"The cost is better than IBM Cloud Pak."

"I rate the product price a six on a scale of one to ten, where one is low price and ten is high price."

"The open-source, unsupported version is available free of charge."

"It is a low-cost solution."

"The solution costs about 20,000 or 30,000 euros per year, per instance."

"The pricing of WSO2 Enterprise Integrator for enterprise subscriptions can be considered expensive, especially from the perspective of someone who prefers open-source software."
