The ability to configure rules to check for consistency has helped
Apiary provides a free tier of the platform which allows a small group of developers to collaborate easily on the design of open source APIs. In addition to this, it provides mock endpoints allowing people to experiment with the API without depending or having to stand up a real backend. With our clients, using Apiary allows us to very quickly pull together an API definition (particularly when using API Blueprint). The whole API design process for the simpler use cases can be done in a relatively short workshop which makes it a lot easier to agree, publish, version-manage an API definition with suitable documentation. This can then be evolved and enhanced (particularly in the documentation aspects). With the ability to support Swagger (Open API v2 and introducing/ed support for v3) and API Blueprint makes it a very versatile tool.

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

"This solution has allowed us to standardize API definitions and bring consistency into our shared components, reducing the effort and cost of using functionality across domains within the organization, with Apiary being crucial to our good API strategy."
"Git integration"
"Quick and easy way to share a new API design with teams."
"I do like the overall performance of the solution."
"I find the generation of mock services very useful, especially when demonstrating for new consumers."
"In two years, there was one time the service was down for an hour or so."
"The feature I find most valuable is that it offers authentication and allows us to develop communication points."
"Vey high - very easy API design with no setup effort"
"The documentation is good."
"WSO2 API Manager is a stable solution."
"I think the best part about WSO2 API Manager is that it's highly customizable because it's open-source. The partnership model is quite lucrative for us, it helps us to go and pitch to our customers. You can build a lot of business models yourself that you want to use. You are able to do a lot of the solutions."
"It is a reliable, stable solution."
"This is a flexible and versatile API management solution that has the power to integrate with more than just API."
"Its open-source features are very good, especially for your production work."
"It handles millions of transactions of API calls per month in our reality, in the Lombardy region in Italy."
"API management lifecycle is the most valuable."
 

Cons

"I don't think this solution is very stable so we try to manage stability from our side."
"The Oracle release cycle is very bad because the patches only update once a year."
"Validation messages could be a bit clearer."
"Better Swagger support."
"Swagger (OpenAPI Specification) and Blueprint Support"
"I would like an integrated option to download a Swagger version of the definition."
"The price and the complexities attached to the solution are two areas of concern where improvements are required."
"The user interface provides all functionalities to configure and manage the product, however its usability, especially for first-time users, is a little bit rough compared to the UI of other commercial API Managers."
"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."
"API Manager is not easy to scale because some of its components lack scalability. It's a difficult point. Especially because companies are so cloud-based these days, microservice scalability is a major thing."
"Improve the possibility to migrate to different versions would be very good."
"The technical support must be improved."
"I would like it to be a more convenient development platform with the ability to write orchestrations and so on. Our problem with this product is that in my country, we are the only enterprise that has been using this product. We're missing a lot of knowledge from colleagues to consult with, and we also aren't able to recruit people with relevant skills. It is a big problem. The small team that is maintaining this product is the only team that can actually relate to any technical issue. The support that we're getting from the company is not great. There is also a cultural gap there because they're from Sri Lanka, and it is not easy. They're putting in a lot of effort, but they are not meeting our expectations."
"We found WSO2 API Manager to be a bit complex."
 

Pricing and Cost Advice

"There is a free subscription option to start and try the service."
"It is easy to get started with personal (free) accounts, but a subscription is required for additional features."
"WSO2 API Manager is a costly solution, and its pricing is not competitive enough compared to other products."
"We have not opted for the paid version of WSO2 but we have implemented the free and open source WSO2 software to a great extent and it is working as per our expectation."
"There is a subscription-based pricing structure and also the open-sourced version available."
"It's not expensive, but it could be cheaper."
"The challenge is the increasing pricing, which has led some customers to consider alternatives, like using Spring Boot solutions instead. The rising costs, especially as cores and usage increase, have been a concern, prompting some to migrate to other products."
"We use the open-source version of WSO2 API Manager, there is no cost."
"WSO2 API Manager is an open-source solution."
"As far as I'm aware, the costs are not minimal but satisfactory."
