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

"It is one of the best integration tools in the market."
"The connectivity the solution provides is excellent. There are often too many systems that we have to integrate and this helps with that."
"Easy connectivity and easy integration."
"The solution has a good graphical interface."
"The architecture based on events has several connectors which allow integration from external and internal applications of the company."
"The solution doesn't require much code writing and we can develop APIs very easily."
"I am impressed with the product's connectors and scalability."
"The solution offers multiple deployment options."
"The solution's technical support is very knowledgeable."
"I like the user-friendly system and development of the service-oriented architecture."
"The customer service executives are very responsive."
"The solution has two main parts: integration and transformation. It's very user-friendly and easy to understand for everyone."
"It's a very complete product. It allows us to network security and add more layers of security to the system."
"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."
"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."
 

Cons

"It would be much more beneficial if the solution included AI and business process management."
"We would like to have a built-in logging framework in which we can do auditing."
"Mule ESB isn't as secure as IBM. Financial companies go with IBM for that reason."
"It should have some amount of logging."
"The initial setup is not easy."
"The current version will not be supported for much longer."
"In an upcoming release, I would like to see more additional concept for exception handling, batch processing, and increased integration with other application."
"There are some features on the commercial version of the solution that would be great if they were on the community version. Additionally, if they added more authorization features it would be helpful."
"There are a lot of security settings that when you apply you have to re-apply again every time you modify a setting. It is something that really needs to be enhanced."
"I would like to see them bring back a feature, from earlier versions, that was very useful in debugging and finding issues."
"The customization can be a bit difficult."
"You cannot include the validation of XPath."
"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 micro integrator should be improved. There is room for enhancement considering alternative integration components."
"One of the reasons that we are looking for a replacement is their way of defining integration. The language of the XML structures that I use to describe the integrations are not that standard, and it's not easy to find people who are familiar with this approach."
"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

"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."
"The price of the Mule ESB commercial version is expensive. However, they have a free community version."
"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."
"The solution is expensive."
"This is expensive. In my next project, we had to go to other vendor."
"You will not get any support from Mule ESB's team for the tool's community edition...You can get support with the licensed version of Mule ESB."
"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."
"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."
"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 pricing of WSO2 Enterprise Integrator for enterprise subscriptions can be considered expensive, especially from the perspective of someone who prefers open-source software."
"The solution costs about 20,000 or 30,000 euros per year, per instance."
"The cost is better than IBM Cloud Pak."
