Executive SummaryUpdated on Mar 3, 2025

Mule ESB and WSO2 Enterprise Integrator compete in the integration platform category. Mule ESB seems to have the upper hand with its wide array of connectors and flexible integration solutions, while WSO2 focuses more on stability and API management.

Features: Mule ESB offers a wide selection of connectors, making it easy for developers to integrate services. It also features DataWeave and Mule Expression Language, enhancing its flexibility and performance. WSO2 Enterprise Integrator provides strong API management and various connectors, with a focus on stability. It supports integration of diverse applications through efficient mediation and transformation capabilities.

Room for Improvement: Mule ESB could improve in providing more stable upgrades, simplifying its documentation, and enhancing SOAP services support. Its high memory consumption and pricing are also areas of concern. WSO2 Enterprise Integrator needs better documentation, simpler customization options, and improved clustering capabilities. Enhancing on-premise analytics support would also be beneficial for users.

Ease of Deployment and Customer Service: Mule ESB supports Public, Private, and Hybrid Cloud setups and offers mixed reviews on customer service. It benefits from community support. WSO2 Enterprise Integrator mainly serves on-premises environments and is generally seen to have satisfactory customer support.

Pricing and ROI: Mule ESB's enterprise version is costly, with various licensing and deployment options, while the Community Edition suits budget-conscious users. WSO2's pricing is considered more affordable for small to medium-sized enterprises, providing open-source flexibility but with potentially high enterprise subscription costs. Both solutions can deliver ROI when used effectively, though Mule ESB may be relatively more expensive.

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

"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."

"This tool has exceptional API management and integration connectors in addition to multiple out of the box connectors."

"I like that it's user-friendly. Compared to other ESBs, I find it easier to use. I like it better than other ESBs. I like the connectors, which make calling the APIs through the routers easier."

"The cloud and integration abilities are most useful allowing us to use applications such as Salesforce and DataWeave."

"The product offers a community edition that is free of cost."

"The most beneficial features of Mule ESB are the control plane and runtime plane."

"The architecture based on events has several connectors which allow integration from external and internal applications of the company."

"The solution's drag-and-drop interface and data viewer helped us quite a lot."

More Mule ESB pros

"It's a very complete product. It allows us to network security and add more layers of security to the system."

"The solution's customer service is good."

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

"The learning curve for this solution is very good."

"The productivity is the most valuable feature. It is very easy to write remediations."

"The customer service executives are very responsive."

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

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

Cons

"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."

"The solution's setup needs to be a bit more straightforward and its support needs to respond faster."

"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."

"The Anypoint platform consumes a lot of memory, and it would be great for developers if it were more lightweight."

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

"The solution isn't as stable as we'd like it to be. There are some ongoing issues and therefore Mule has to provide frequent patches. Mule's core IP should be more stable overall."

"In order to meet the new trend of active metadata management, we need intelligent APIs that can retrieve new data designs and trigger actions over new findings without human intervention."

"There are some issues with both stability and scalability."

More Mule ESB cons

"The product's price is an area of concern where improvements are required."

"If I have to buy software, then it becomes expensive for me."

"They should introduce better pricing for small companies."

"The micro integrator should be improved. There is room for enhancement considering alternative integration components."

"The setup can be difficult for those not familiar with the solution."

"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."

"In my opinion, the administration model and interface, of Carbon, are lacking in terms of its features and user experience."

"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."

More WSO2 Enterprise Integrator cons

Pricing and Cost Advice

"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."

"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."

"I think the price is very high. If you use TIBCO BW, the license is for the CPU usage, then the IPS, and support. I also think the license for the product is a one-time expense."

"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 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."

"Mule ESB is an expensive solution."

More Mule ESB pricing and cost advice

"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 cost is better than IBM Cloud Pak."

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

"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."
