Sentiment score

webMethods.io customer service is praised for quick support, though responses vary, with suggestions for localized and faster service.
We have a good relationship with our vendor, and they are ready to help us with any technical issues.
The technical support of Mule ESB can be rated from nine to ten.
 

Scalability Issues

Sentiment score
7.6
Mule ESB is scalable, ideal for cloud deployments, and suits medium to large enterprises with proper configuration.
Sentiment score
7.2
webMethods.io is highly scalable for cloud solutions and adaptable for large integrations, despite licensing and configuration challenges.
Mule ESB is a scalable solution.
Whenever more resources are needed, they become available automatically without any human interference.
Vertically, scalability is fine, however, I have not expanded horizontally with the product yet.
 

Stability Issues

Sentiment score
7.2
Mule ESB is generally stable and reliable, but improvements are needed in clustering, large files, and CloudHub stability.
Sentiment score
7.6
webMethods.io is stable and reliable with minor issues, enhanced by frequent updates, though rapid changes can be problematic.
There are some issues like the tool hanging or the need for additional jars when exposing web services.
We provide support to our clients, and the minimum calls I receive are for webMethods.io; it's very stable.
 

Room For Improvement

Mule ESB faces criticism over documentation, setup complexity, pricing, stability, scaling issues, regulatory challenges, and frequent release versioning.
webMethods.io needs better documentation, stability, integration, performance, and user-friendly features, including cost-effective licensing and advanced capabilities.
More information is needed from MuleSoft.
From my perspective, Mule ESB is lightweight, but it can be improved when it comes to the agility of the system.
Another enhancement would be in OCR; currently, there is a huge demand for OCR capabilities. It would be perfect if webMethods.io had a built-in component for OCR, as this would be tested and allow customers to use it better than a third-party OCR application.
A special discount of at least 50% for old customers would allow us to expand our services and request more resources.
 

Setup Cost

Mule ESB is costly, especially for small businesses, but its robust features and integration support offer significant value.
webMethods.io is costly, ideal for big enterprises; licensing complex; negotiations common, but valued for its capabilities and support.
Regarding the pricing and licensing of webMethods.io, I don't think it's expensive when compared with the features.
 

Valuable Features

Mule ESB offers user-friendly integration with robust features like connectors, data transformation, cloud integration, and microservices support.
webMethods.io provides scalable integration, intuitive API management, extensive connector support, robust security, and seamless connectivity for complex integrations.
They have their own language called DataWeave, which helps transform data and is efficient enough to handle any kind of transformation.
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.
It facilitates the exposure of around 235 services through our platform to feed various government entities across the entire country.
I believe data transformation is exceptional in webMethods.io because they have an online database that can cache the database online.

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.
