May 2026
Learn what your peers think about WSO2 API Manager. Get advice and tips from experienced pros sharing their opinions. Updated: May 2026.
900,277 professionals have used our research since 2012.
What do I think about the stability of the solution?
It seems good based on the client's claims and what we've seen in our benchmarking.
I would rate the stability a nine out of ten.
What do I think about the scalability of the solution?
I would rate the scalability an eight out of ten. But the latency can be improved with better scalability, so that would be ideal.
From the client's perspective, around 20 to 30 interfaces are involved in their batch processing. From the administrative side, around 40 to 50 users use it.
How are customer service and support?
We've had certain issues where we posted queries and got responses. Thankfully, none were blockers so far. So we haven't needed to formally contact support.
So we don't have to conduct support. We had good interactions.
Which solution did I use previously and why did I switch?
We used some lightweight solutions that we replaced with WSO2 API Manager.
We were looking for a solution that could handle a complex gateway with multiple components, balancing, routing, and business process automation.
Our previous solution offered basic load balancing and monitoring, but for our business needs, we needed more. WSO2 API Manager offered the features we checked and felt it was a step up to an enterprise-level product with better technical support.
How was the initial setup?
The complexity of the setup is kind of medium; it's not super easy, but not super difficult either. You can manage it if you learn the roadmap properly.
We've been using it on-premises. Right now, we're planning to move it to the cloud.
What about the implementation team?
Deployment depends on various factors, but typically, it can be done relatively quickly.
What's my experience with pricing, setup cost, and licensing?
It's costly.
What other advice do I have?
It's a stable product with good features that are well-bundled. The documentation is helpful, and there are many community resources available if you need custom integrations.
Most importantly, it has many plugins for integrating with various databases, which are standard integrations in the market today. You don't need to code them yourself; you can just use the plugins for integration and easy access.
Overall, I would rate the solution a nine out of ten.
Which deployment model are you using for this solution?
On-premises

Good routing and authentication features but little complex to use
Pros and Cons
- "It's a good product."
- "We found WSO2 API Manager to be a bit complex."
What is most valuable?
I have used features like routing and authentication, as well as the most well-known features of WSO2.
What needs improvement?
WSO2 API Manager has some support problems and can be a little complex. So our developer teams decided to use 3scale or Kong instead. We found WSO2 API Manager to be a bit complex.
So, in terms of complexity, WSO2 API Manager has some challenges. Also, there is a bit of an issue with the pricing and license of WSO2. It's a little high.
For how long have I used the solution?
I used WSO2 API Manager for two projects. However, I can't say I have used it all the time. I have about 50% experience and knowledge about it.
How are customer service and support?
We are not satisfied with the customer service and support. In a few instances, their response time has been a bit slow.
How would you rate customer service and support?
Neutral
How was the initial setup?
It is difficult to implement WSO2. The implementation can vary depending on various factors, such as the features required and the availability of human resources, including developers. It could take anywhere from two to three months or even just one week, depending on the specific requirements.
What about the implementation team?
Our team worked together with our developers to carry out the implementation.
What's my experience with pricing, setup cost, and licensing?
For our projects, we found it to be a little high. However, it may not be the case for another company or project. Because the costs depend on the specific features you would require and other factors.
What other advice do I have?
It's a good product. I prefer it. However, I would only recommend using WSO2 API Manager if the user has a specific requirement for one of its features. If they don't have a specific reason for using it, I can't provide a recommendation because it depends on factors such as the project, the local team, and the desired features. The API management system is complex by default. Therefore, the selection primarily depends on the project and the programming platform used by the developers.
Overall, I would rate WSO2 API Manager a seven out of ten because there is still room for improvement.
Disclosure: My company does not have a business relationship with this vendor other than being a customer.

Which solution did I use previously and why did I switch?
I have experience using another API management solution from a larger company. Comparing WSO2 API Manager, it has its strengths in flexibility and customization based on our requests. It also has robust features and components. But in terms of cons, it can be complex and may take some time to set up compared to simpler solutions.
How was the initial setup?
The setup was a bit complex because we initially started with enterprise professional services, but later transitioned to the open-source version which required more effort to set up.
We didn't encounter many challenges while integrating WSO2 API Manager with other systems as we primarily focused on setting up our own solution. We mainly relied on the solution itself for updates and upgrades.
Our deployment involved setting up two rings in the cluster and transitioning from testing to production. It took some time to learn the deployment process, especially with the enterprise version.
What about the implementation team?
We completed the set-up in-house. One person is required for handling the deployment for the enterprise aspect.
What other advice do I have?
We haven't implemented any AI-driven solutions or encountered AI-driven issues within our company.
I would recommend WSO2 API Manager to other users, especially if they value a robust support system and are ready to invest in the deployment process. However it is important to consider factors like support costs and licensing models before making a decision.
In terms of overall rating, I would give it a seven out of ten, taking into account both its advantages and limitations.

We have 1,000 users on the solution.
How are customer service and support?
We had support every time we needed it; we could reach support without a problem.
How would you rate customer service and support?
Positive
How was the initial setup?
The initial setup is not complex. You can install everything together in what they call an all-in-one setup, or you can install each model separately. It's not difficult to install.
If I had to rate the initial setup of WSO from one to five, I'd rate it a four out of five.
What's my experience with pricing, setup cost, and licensing?
I don't deal with the licensing aspect of the product.
What other advice do I have?
I'm starting with Microsoft as our API manager on a daily basis.
I'm working as a project manager and architect, so I don't install the products. However, I understand their texture and how the parts interact with each other.
I'd advise new users to have a company that knows it very, very well. If you don't don't know the product at the beginning, you can make a mess of your project. Choose a good partner first to make everything easier.
I would rate the solution eight out of ten. It's a good product.
