I use the solution in my company to deal with use cases, like certain developments in webMethods.io. I had used the tool to deal with API implementation, which was something that was related to integration with the help of APIs. We used to provide APIs to our partners as an organization so that they can use our API and the logic we have written under the APIs, which can help them get the information they want based on the APIs.

Mule ESB
March 2026
Learn what your peers think about Mule ESB. Get advice and tips from experienced pros sharing their opinions. Updated: March 2026.
885,264 professionals have used our research since 2012.
What do I think about the scalability of the solution?
Around 100 to 200 people in my company use the product.
Which solution did I use previously and why did I switch?
I have experience with TIBCO ActiveMatrix Service Bus. I have fifteen years of experience with webMethods.io.
Compared to Mule ESB, you will find that there are fewer coding challenges in webMethods.io.
How was the initial setup?
The solution is deployed on an on-premises model.
A six to seven-member team, including one or two managers, is required to take care of the technical part of the product.
What about the implementation team?
My company had sought help from an integrator to deal with the product's deployment process.
What's my experience with pricing, setup cost, and licensing?
The product offers a community edition that is free of cost. 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.
Which other solutions did I evaluate?
My company did evaluate other options in the market, considering that we need to start any integration-related discussions by speaking about how complex integration can be for us before choosing the product that can be better for us.
What other advice do I have?
Mule ESB supported our organization with its archiving capabilities, like the way we used to receive support from webMethods.io. My company used to raise tickets with the support team if we faced any issues with the product. If the product's support team were able to resolve our issues with the tool, they would send our company emails with complete solutions to our issues. The support team also used to try to fix our company's issues with the product through share screen options.
I only use the product's API part, and I haven't seen any issues with the product. Owing to the aforementioned reasons, I can't comment on the product's features that I find to be most effective for our company's integration needs. I like the development part of the product. I can't comment on the stability of the product since I used to use it in the environment as it does not move to the cloud. The development was not that easy in Mule ESB compared to webMethods.io, which offers a flow service.
I would recommend webMethods.io to others since I have a good understanding and knowledge of the tool. If people still insist on looking for other products, I need to involve another person who can provide them with the right judgment. Maybe someone who has worked on both of the products simultaneously can be an intelligent person. If you ask my individual opinion, I would go with webMethods.io.
Mule ESB is more inclined towards Java codes. If you are a new user who knows about Java, then Mule ESB will be easy for you to use. With webMethods.io, you can use it even without knowing any coding language. Considering the aforementioned comparison, I feel that webMethods.io is better than Mule ESB.
I rate the overall tool a six out of ten.
Which deployment model are you using for this solution?
On-premises

- "It would be beneficial if users could navigate the UI easily without extensive training or learning curves."
What is our primary use case?
Mule ESB excels in orchestrating workflows and seamlessly integrating with business implementations while keeping technical details hidden. It also offers protocol transformation, converting between different protocols, and supports service exposure to customers while maintaining technical invisibility.
What is most valuable?
We utilize data transformation capabilities extensively. 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. For smaller data transformations, we rely on DSPS.
What needs improvement?
One notable drawback is the user experience aspect, particularly in terms of self-service functionality within Mule ESB. It would be beneficial if users could navigate the UI easily without extensive training or learning curves.

Mule ESB is scalable because it can be easily scaled in a cloud deployment and is containerized, making scaling up or down straightforward. This shouldn't be a major concern nowadays.
How are customer service and support?
MuleSoft's customer support is excellent.
How would you rate customer service and support?
Positive
How was the initial setup?
Setting up Mule ESB is relatively easy, although it depends on factors like account categorization and whether you're using Docker or Kubernetes.
What about the implementation team?
Typically, installation and configuration take around three to four days initially, but subsequent deployments or updates are quicker. One engineer or developer is usually sufficient for deployment, but implementation complexity may vary based on the use case.
What was our ROI?
The ROI of Mule ESB is greatly influenced by the design and governance of the solution, particularly focusing on reusability and adherence to microservices architecture. Properly designing and implementing these aspects can significantly enhance ROI.
What's my experience with pricing, setup cost, and licensing?
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.
What other advice do I have?
Working with Mule ESB has taught us the value of experience with different ESBs, making it easier to adapt to new solutions.
Overall, I would rate the solution a ten out of ten.

It has a user-friendly design with everything all in one place
Pros and Cons
- "Mule ESB has a user-friendly design, and everything is in one place. The API and architecture are popular right now. Also, MuleSoft has a large and supportive online community."
- "Mule ESB has a user-friendly design, and everything is in one place."
- "MuleSoft isn't as mature as some other integration technologies out there like IBM WebSphere. There's room for growth, and MuleSoft is working toward that."
- "MuleSoft isn't as mature as some other integration technologies out there like IBM WebSphere."
What is our primary use case?
My current client is using Oracle Fusion Middleware as their integration platform, and they want us to build a new platform enabling the same functionality using MuleSoft.
What is most valuable?
Mule ESB has a user-friendly design, and everything is in one place. The API and architecture are popular right now. Also, MuleSoft has a large and supportive online community.
What needs improvement?
MuleSoft isn't as mature as some other integration technologies out there like IBM WebSphere. There's room for growth, and MuleSoft is working toward that. They're already implementing a graph system, which should help organize the APIs in a branched way. It looks more like a relational database now. They're also working on MuleSoft Composer. These are the features that they're working on.
For how long have I used the solution?
We've used Mule ESB for four years now.
What do I think about the stability of the solution?
Mule ESB is stable.
What do I think about the scalability of the solution?
Mule ESB is scalable.
How are customer service and support?
I haven't personally contacted MuleSoft support. Our team has contacted them during some test scenarios, and they were responsive. I would rate MuleSoft support a solid nine out of 10 based on my limited experience with them.
Which solution did I use previously and why did I switch?
I have little experience with Oracle Fusion. It's quite good, but the interface is pretty old-fashioned. I worked with IBM WebSphere as well. That was a big part of another project I worked on, but these are the two technologies I've used.
Currently, I'm working with Oracle Fusion. These solutions require elaborate coding, so you need to be extremely experienced in programming, with the ability to write tons of complex code. It's good to have a solid background in coding, but you shouldn't need to be an expert to work.
How was the initial setup?
Mule ESB isn't difficult to set up, but there are specific procedures you need to follow. Prerequisites need to be in place to set up the whole environment. It's straightforward once you set up the platform.
After deployment, it doesn't require much maintenance. Most things can be automated, so you don't need someone to always monitor the solution. Ultimately, it depends on your use case.
What other advice do I have?
I rate Mule ESB nine out of 10. It works well for me. If you're using Mule ESB for the first time, I recommend taking advantage of the free training. If you go through that training, you'll have a basic understanding of the technology. That's a good starting point.

Conversion and transition performance is solid
Pros and Cons
- "I'm not using ESB directly. It is the integration layer, so it's running under the hood. However, the conversion and transformation performance is excellent. Anypoint Enterprise Security is also solid."
- "It provides seamless support and transition."
What is our primary use case?
ESB is middleware for interacting with multiple heterogeneous systems. Our most critical use case is ensuring the connection is ready, systems are interacting seamlessly, data conversion is happening, and the business logic is being applied.
The solution is the middleware between the producer and a consumer, and we ensure that the producer is creating the data according to the consumer's requirements. If any orchestration or any transformation is necessary, then MuleSoft performs that.
What is most valuable?
I'm not using ESB directly. It is the integration layer, so it's running under the hood. However, the conversion and transformation performance is excellent. Anypoint Enterprise Security is also solid.
For how long have I used the solution?
I've been working with ESB for two years, but I'm not exposed to the coding or developing aspects. It is part of the integration layer, and I deal with middleware integration testing.
What do I think about the stability of the solution?
Mule ESB's stability is also good.
How was the initial setup?
We have a four-person DevOps team that performed the initial setup, so I wasn't involved, but I think the deployment would be smooth and straightforward because it's on the cloud.
What other advice do I have?
Nine out of 10. It's one of the better open-source tools for development. It provides seamless support and transition. I give it a high rating because most organizations are using MuleSoft.
IBM and Oracle are also in the middleware market. MuleSoft is open-source and readily available, so people can meet their needs easily with this tool. We have a REST API with minimal integration and configuration, so we can easily use this solution.
Which deployment model are you using for this solution?
Hybrid Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)
