Has required significant improvements due to limited features but offers simple implementation and good support
Boomi AtomSphere API Management has very few features. If you ask me to name the top two, I would say MuleSoft and Apigee, as it depends on the customer-to-customer use cases. After those, WSO2, Kong, and whether you say Informatica API Manager or Boomi AtomSphere API Management, they stand with only three out of ten features which are essential for API management. All the features that Apigee has, they need to add. All the features that MuleSoft has, they need to add. It is not a simple task. The problem is that they lack features. It is not their performance. There are many features to mention. When you take and compare all the features that Apigee has and all the features that MuleSoft has, they need to implement those features.

Middleware integration has become smoother and manages API lifecycles and scopes effectively
Regarding WSO2 API Manager, I have no drawbacks or areas for improvement. However, regarding the Micro Integrator, I had some issues while developing complex services because it was mainly designed to be used for simple services, not complex ones. While using complex services, I encountered some issues. I communicated this with WSO2, and they released other products that solved everything related to my concern. These products were released before my concern was raised. When I explored them, they were pretty good, and I did not see the same issues I had experienced. WSO2 is enhancing themselves, and their products are fine. The previous concern was about the previous product, so it is resolved now since there are new products available. I would like WSO2 to improve quality or response time in support, or both.

Quotes from Members

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

Pros

"AtomSphere API Management is a simple platform that's easy to use. If you're using it on-prem, there's a little learning curve."
"AtomSphere is tightly integrated into the Boomi iPaaS platform. And Boomi has been augmenting AtomSphere API Management for the past couple of years so version 2.0 is better than 1.0."
"We can create APIs straightforwardly and quickly and build jobs for data migration."
"Integration is straightforward. There is no issue with it."
"The product's stability is good."
"The stability of the solution is good."
"We can develop almost any interface that we need."
"The user interface, which we use to create the integration, basically has the data structures collected, is pretty easy to navigate, is a drag and drop style of working, and there is very little code required so the creation of the endpoints is very simple."
"WSO2 API Manager provides strong internal API security, including token-based authentication and HTTPS support for various formats like REST. However, the newer API security features that are emerging are not available yet. They might be in development, but for now, internal API security is well-covered."
"It handles millions of transactions of API calls per month in our reality, in the Lombardy region in Italy."
"The advice I have for any of the organizations or companies looking for an API manager is that they, first of all, verify the building block before selecting a product."
"WSO2 is very easy to install and has all the main functionalities that we are looking for when we want to put up the management solution like a friendly UI tool, SOAP to REST API publication options, plugin extensions, adding OAuth 2.0 to the operations, installing on-premise, handling multiple versions of the same API, and importing and exporting Swagger."
"The scalability is fine for our purposes."
"It is a reliable, stable solution."
"A complete integration suite and a good platform."
"Yes WSO2 API Manager is scalable"
 

Cons

"Scalability is an area where Boomi lacks."
"Boomi AtomSphere API Management has very few features. If you ask me to name the top two, I would say MuleSoft and Apigee, as it depends on the customer-to-customer use cases."
"Overall, I would rate AtomSphere lower than solutions like APG or API Connect."
"To some degree, you need to know what type or amount of API you are creating - whether it's a rest API or web service API. You need to know ETL in order to really get the most out of Boomi."
"From an improvement perspective, the price could be cheaper."
"It's difficult to integrate the on-prem application with the Dell Boomi Cloud. We have to check to ensure the Dell domain engine is running. It just requires some service endpoints from our on-prem application to connect to Dell Boomi Cloud to make it available to integrate. It would be better if AtomSphere API Management were offered as a purely SaaS application, so I wouldn't need an on-prem component to make it available. We could make a test call or provide some connection parameters. That should enable it to pull the data."
"The product is really complex to manage."
"Most of the basic functionality is there in Boomi, but APG is a more feature-rich solution."
"WSO2 API Manager should improve its marketplace subscription model and documentation in order to reach a higher level in the market."
"Integration is an area that needs to be improved."
"They are developing another platform called Choreo that allows you to create API itself using the WSO2 programming language Ballerina. It would be great if they added a direct connection between Choreo and API Manager, that would be great. I think they are working on that, but I'm not sure."
"WSO2 API Manager could improve the API approval system."
"The initial setup can be difficult."
"The professional support and licensing aspects of WSO have been a challenge."
"I would like to see improvements in the speed of the solution as it can be a bit slow compared to other platforms along with addressing memory issues would be beneficial."
"Basically, mTLS is a certificate-based communication protocol that WSO2 API Manager doesn't support."
 

Pricing and Cost Advice

"The price is reasonable."
"Boomi AtomSphere API Management gives customers a good price. Price-wise, the product is good."
"Boomi AtomSphere API Management is a cheap product."
"The product can get very expensive quickly if you connect to multiple databases."
"My previous company paid about 1.2 million dollars, and my current company pays about 300k. Both companies are at the enterprise level."
"As far as I'm aware, the costs are not minimal but satisfactory."
"It's not expensive, but it could be cheaper."
"It is an open-source product."
"We use the open-source version of WSO2 API Manager, there is no cost."
"We use the open-source version — the free version."
"I think the other competitors that are providing the same solution are quite expensive. WSO2 API Manager is quite cheap."
"For our projects, we found the pricing to be a little high."
