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

"The feature I find most valuable is that it offers authentication and allows us to develop communication points."
"I do like the overall performance of the solution."
"I find the generation of mock services very useful, especially when demonstrating for new consumers."
"Git integration"
"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."
"Quick and easy way to share a new API design with teams."
"Vey high - very easy API design with no setup effort"
"In two years, there was one time the service was down for an hour or so."
"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."
"The most beneficial feature of WSO2 API Manager is its capability to use Swagger to define and then populate the API."
"Functionality-wise, I like WSO2 API Manager - Publisher API and WSO2 Enterprise Service Bus."
"I think the best part about WSO2 API Manager is that it's highly customizable because it's open-source."
"The main feature — the publication of the API, the management section — is great in general."
"Its open-source features are very good, especially for your production work."
"The solution is stable."
"Yes WSO2 API Manager is scalable"
 

Cons

"The Oracle release cycle is very bad because the patches only update once a year."
"Better Swagger support."
"Swagger (OpenAPI Specification) and Blueprint Support"
"I would like an integrated option to download a Swagger version of the definition."
"I don't think this solution is very stable so we try to manage stability from our side."
"Validation messages could be a bit clearer."
"The interface needs to be modernized and made more user friendly so the product continues to have a growing community of users."
"The support system is not that great."
"The technical support must be improved."
"The stability is pretty good, but it could be improved."
"I think they could greatly improve the general UX with their solutions."
"Basically, mTLS is a certificate-based communication protocol that WSO2 API Manager doesn't support."
"WSO2 API Manager can be improved a lot relating to usability"
"From a product perspective, the first thing is that although the documentation provided by WSO2 is good, it could be much better. We're in the middle of a complex migration, moving away from VMs to Kubernetes with the latest version of WSO2 and good documentation is essential to us right now."
 

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."
"For our projects, we found the pricing to be a little high."
"The solution costs less than 20,000 euros a year. I'm not sure of the exact number."
"We use the open-source version of WSO2 API Manager, there is no cost."
"I am using the free version."
"WSO2 API Manager is quite an expensive tool. I rate the product's pricing a nine on a scale of one to ten, where one is low and ten is high."
"It is costly, around ten thousand per year, per instance"
"As far as I'm aware, the costs are not minimal but satisfactory."
"There is a subscription-based pricing structure and also the open-sourced version available."
