Offers strong integration capabilities and reliable features but needs pricing and scaling improvements

Many things are evolving with the AI buzz in the market. What I would like to see improved or enhanced in webMethods.io in the future is that since webMethods.io is already under IBM, I think IBM will introduce and integrate AI into it. Additionally, regarding what webMethods.io can improve is the license cost. Other cloud players are also providing the same kind of functionality, such as AWS and Azure. webMethods.io is being installed on-premises, but AWS is providing it directly in the cloud. When comparing the license cost and request per minute cost, webMethods.io needs to address that. There are many competitors in the market for this.

Quotes from Members

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

Pros

"The core is very stable."

"One of the most valuable features is being able to implement business processes while keeping track of the design from BPMN to a BPEL Implementation."

"OpenESB pushes the organization to clearly define service boundaries and interfaces. So it motives the business and the development teams to clearly define their business services and processes they want to implement. OpenESB supports fine and coarse-grain granularity for the services and supports top-down and bottom-up approaches for the services, processes definition, and composition."

"The process-oriented solution allows you to define choreography and orchestration."

"The tool helps us to streamline data integration. Its BPM is very strong and powerful. The solution helps us manage digital transformation."

"We have a reusable code that we can replicate for any new interfaces."

"In the API gateway, there is a new feature that allows us to filter logs within a payload. This has been a useful feature."

"What I like the most about the solution is that it comes with ready-made tools like handling security tokens and OAuth."

"It has a good integration server, designer, and a very good API portal."

"Most of the work in our organization can be more easily done using the tool."

"One [of the most valuable features] is the webMethods Designer. That helps our developers develop on their own. It's very intuitive for design. It helps our developers to speed the development of services for the integrations."

"They are the building blocks of EAI in SAG products, and they offer a very good platform."

Cons

"The documentation needs to be better."

"The documentation of the product must be improved. It could be tricky to find the right documentation on a topic since the documentation is spread in many places. I advise the new joiner to contact the community to get entry points and additional documentation. Tutorial and Video must be present to take up the product."

"Cloud deployment is weak and needs to be improved."

"Regarding its management, a web console being able to synchronize distributed instances would be great."

"I'd like to see the admin portal for managing the integration server go up a level, to have more capabilities and to be given a more modern web interface."

"The solution's release management feature could be better."

"When migration happens from the one release to an upgraded release from Software AG, many of the existing services are deprecated and developers have to put in effort testing and redeveloping some of the services. It would be better that upgrade releases took care to support the lower-level versions of webMethods."

"The deployment should be simplified."

"The price has room for improvement."

"The solution should include REST API calls."

"The on-premises setup can be difficult."

"The certifications and learning resources are not exposed openly enough. For instance, they have a trial version which comes with only a few basic features, and I think that community-wise they need to offer more free or open spaces where developers can feel encouraged to experiment."

Pricing and Cost Advice

"The cost for the prediction instrument is high because it is charged per instances based on prediction, but the rest of the solution is free."

"There are two versions. The first is the community version, which is free and contains the last part of the feature, but if you want to get the Enterprise version, you'll have to pay €60,000 which covers support and two instances on production."

"The Community Edition is a full product you can use in production, it does not have limitations like other alternatives."

"Based on our team discussions and feedback, it is pretty costly because they charge us for each transmission."

"I don’t have much idea about prices, but webMethods API Portal is not something cheaper."

"I do see a lack of capabilities inside of the monetization area for them. They have a cloud infrastructure that is pay per use type of a thing. If you already use 1,000 transactions per se, then you can be charged and billed. I see room for improvement there for their side on that particular capability of the monetization."

"It is an expensive tool. I rate the product price a nine out of ten, where ten means it is very expensive."

"I would like to see better pricing for the license."

"The price is a little bit high, especially regarding their support."

"This is not a cheap solution but, compared to other products such as those offered by IBM, the pricing is similar."

"I do think webMethods is coming under increasing pressure when it comes to their price-to-feature value proposition. It's probably the single biggest strategic risk they have. They're very expensive in their industry. They've been raising the price recently, especially when compared with their competitors."
