Easy to set up with a good enterprise integrator and great reliability
Pros and Cons
- "The solution is stable."
- "The user interface could be a bit better."
What is our primary use case?
What is most valuable?
The main feature is the enterprise integrator. It's very important to API management. You can implement SOA strategy in the company using the API Manager. Some companies were just using enterprise integrators at the beginning. For implementers, they had to install it to use the API management and identity the server to have more security in the system.
The solution is stable.
It's scalable.
It is easy to set up.
What needs improvement?
They've already improved a lot of features between versions six and seven.
The user interface could be a bit better. Sometimes you have different visual aspects when you change from one screen to another.
For how long have I used the solution?
I'm implementing a WSO2 project right now. I've used the solution for the last six months.

Helps to expose APIs to the outside world
Pros and Cons
- "WSO2 is very stable."
- "We had some problems with the reverse proxy not being able to invoke fully qualified domain names, so we have to build some custom scripts to solve this issue."
What is our primary use case?
We are a banking solution and use WSO2 to offer our services to banks.
How has it helped my organization?
WSO2 helps to expose our internal APIs to the outside world.
What needs improvement?
We had some problems with the reverse proxy not being able to invoke fully qualified domain names, so we have to build some custom scripts to solve this issue. In the next release, WSO2 should make multifactor authentication simpler.
For how long have I used the solution?
I've been using WSO2 API Manager for two years.
What do I think about the stability of the solution?
WSO2 is very stable.
What do I think about the scalability of the solution?
WSO2's scalability is very good because we deployed using a microgateway-driven approach on OCP, which takes care of scaling. I would rate its scalability as 4.5 out of five.
How are customer service and support?
WSO2's technical support is good.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
I previously used IBM App Connect but switched to WSO2 for a number of reasons, including cost, complexity, technical resource availability, troubleshooting, and multiple practice.
How was the initial setup?
The pattern we followed to set up WSO2 was a bit complex, but the end goal was very clear, so the setup itself was straightforward and took about two days. I would rate the setup experience as four out of five.
What about the implementation team?
We used a third-party team.
What other advice do I have?
I would advise anybody thinking of implementing WSO2 to go for it. I would give WSO2 a rating of eight out of ten.
Which deployment model are you using for this solution?
On-premises

Simple interface, simple implementation, but rate-limit could improve
Pros and Cons
- "WSO2 API Manager's most valuable features are the simple interface that is easy to use and the APIs lifecycle."
- "WSO2 API Manager could improve the API approval system."
What is our primary use case?
We use WSO2 API Manager to manage APIs.
What is most valuable?
WSO2 API Manager's most valuable features are the simple interface that is easy to use and the APIs lifecycle.
What needs improvement?
WSO2 API Manager could improve the API approval system.
For how long have I used the solution?
I have been using WSO2 API Manager for approximately one year.
What do I think about the stability of the solution?
The stability of the WSO2 API Manager is good.
What do I think about the scalability of the solution?
We have used the open-source version, but I'm we have now switched to the enterprise version, I am not of the differences. The rate-limiting in the open-source seems not to work. When I add buy limits, it does not work correctly. I do not think this issue is in the enterprise version.
This solution is suitable for medium to large businesses.
How are customer service and support?
The technical support from the WSO2 API Manager is very good. When there is an issue they fix the ticket very quickly.
Which solution did I use previously and why did I switch?
I have not used other API management systems.
How was the initial setup?
The initial setup of WSO2 API Manager is simple.
What's my experience with pricing, setup cost, and licensing?
WSO2 API Manager is a low-cost solution. It is one of the most affordable solutions.
What other advice do I have?
I find the solution to be good overall. The solution is receiving a lot of attention and is attracting investors.
I rate WSO2 API Manager a seven out of ten.
Which deployment model are you using for this solution?

A complete solution for designing and publishing with useful open-source features
Pros and Cons
- "Its open-source features are very good, especially for your production work."
- "They don't have different URLs for administrators."
What is our primary use case?
We're currently evaluating WSO2 API Manager and Kong for development environments and not production environments. We're currently using Apigee and AWS API Database for the production environments.
What is most valuable?
Its open-source features are very good, especially for your production work. If your workload's still running in an on-premises environment, WSO2 is a good product.
I like a few WSO2 plugins we're using for routing, message request transformation, or response transformation. I also like the security encryption feature.
Another thing I like about WSO2 is the nice training and tutorials they have on their website. They have my type of training on their website for API gateway and open banking. They're all self-based training, and you can go to those training pages or videos and learn in your free time.
What needs improvement?
They don't have different URLs for administrators. They should have one in place like Kong. For example, Kong has Konga as an administrative URL, where everything is available in one place for submissions and subscribers. But with WSO2, they have exposed it on a different port, and if I want to publish, I have to open a different URL with a different port for publishers and subscribers. It'll help if they can combine it on one port. WSO2 API Manager could also be somewhat cheaper.
For how long have I used the solution?
I have been using WSO2 API Manager for more than one or two months.
What do I think about the stability of the solution?
It looks like a stable product.
What do I think about the scalability of the solution?
WSO2 API Manager is a scalable solution.
Which solution did I use previously and why did I switch?
WSO2 is the first open-source solution we're trying out. But we're still using Apigee from Google and AWS API Database from Amazon.
How was the initial setup?
The initial setup is straightforward, and not much effort is required for installation. It's simple.
What about the implementation team?
We implemented it by ourselves. It took about two people to set up and deploy.
What's my experience with pricing, setup cost, and licensing?
It's not expensive, but it could be cheaper.
What other advice do I have?
I would recommend it as I think it is good.
On a scale from one to ten, I would give WSO2 API Manager an eight.
Which deployment model are you using for this solution?
On-premises

Great API management, but there are better solutions available
Pros and Cons
- "The main feature — the publication of the API, the management section — is great in general."
- "I think they could greatly improve the general UX with their solutions."
What is our primary use case?
We use it along with IdentityServer, as our main API management tool for API exposure to the internet. It's not for internal usage, it's for external use.
We have two main roles regarding WSO2 API Manager. There are the admins, who publish guides and user updates, etc — we employ around four people who perform this role. In terms of users, we have around five to six million users going through it on a monthly basis.
What is most valuable?
The main feature — the publication of the API, the management section — is great in general.
What needs improvement?
I think it would be very unfair for me to answer this question because we are running a very outdated system (they might have improved it a lot with their newer versions), but I'm going to try it anyway. I think they could greatly improve the general UX with their solutions because when you manage different components that are meant to work together, it's very difficult. You have to deal with two completely unrelated interfaces.
Perhaps they should include a tool to assist with migrating to Azure.
For how long have I used the solution?
I have been using WSO2 API Manager for the past four to five years.
What do I think about the stability of the solution?
Stability-wise, it's actually pretty nice — it's good. I wouldn't say it's very good or excellent, but it's good. It fits the bill.
What do I think about the scalability of the solution?
Scalability-wise, I'd give it a three-star rating out of five — good, but not very good or perfect.
The provisioning has to be done manually. In terms of system-wise configurations, these settings involve a lot of big Java components, so it's not natural. It's not very easy to handle. Again, this is an older version. Perhaps they have already worked on this.
How are customer service and technical support?
We don't have a contract for dedicated support. We have to deal with internet forums, etc. Officially speaking, there's no support outside of community forums.
The documentation and community support are pretty helpful. There are a lot of questions answered about WSO2 on several forums and message boards, etc. Although it's not dedicated, it's quite relevant.
Which solution did I use previously and why did I switch?
We're actually in the process of switching to Microsoft Azure API management.
For us, the main benefit of Azure is that it's a managed solution. We have a very restricted theme and not having to deal with the actual configuration of the platform or the underlying operating system and other intrinsic administration tasks is a big win for us. The feature that we use the most and that is most licensed is perhaps the online portal. The certified online portal is the biggest win for us because we can deal with the associated integrations within this new portal, which we can't in the current stack, the on-premises stack.
How was the initial setup?
I wasn't a part of the original project, but I know that the initial setup wasn't easy.
What's my experience with pricing, setup cost, and licensing?
We use the open-source version — the free version.
What other advice do I have?
I wouldn't actually recommend this to anyone. I think that there are paid solutions, such as Azure API Management, which will relieve you from the administrative burden. Personally, I wouldn't recommend this solution at all.
On a scale from one to ten, I would give WSO2 a rating of seven. It's a good tool, but dealing with the on-premises infrastructure is a big headache.
Which deployment model are you using for this solution?
On-premises

A simple solution with good API management lifecycle, but needs better support and the ability to write orchestrations
Pros and Cons
- "API management lifecycle is the most valuable."
- "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."
What is our primary use case?
It is basically used for the integration of applications inside the organization and also for business partners outside the organization.
What is most valuable?
API management lifecycle is the most valuable.
What needs improvement?
I would like it to be a more convenient development platform with the ability to write orchestrations and so on.

I have been using this solution for three years. I have used it in production for two years.
What do I think about the stability of the solution?
It is stable.
What do I think about the scalability of the solution?
It is scalable. We have a few dozen users.
How are customer service and technical support?
The support that we're getting from the company is not great.
How was the initial setup?
It was pretty straightforward. The deployment took a couple of weeks.
What about the implementation team?
We had a reseller who is not an integrator. So, we basically did everything in-house.
Which other solutions did I evaluate?
We only did it in a very superficial way. We didn't really evaluate.
What other advice do I have?
I would say if you're looking for a simple and straightforward solution, it is probably a good idea, but if you're looking for a more advanced option, then you should go for some other solution.
I would rate WSO2 API Manager a seven out of ten.
Which deployment model are you using for this solution?

Provides OAuth2 token capabilities, but interface should be more user-friendly
Pros and Cons
- "WSO2 API Manager provides OAuth2 token capabilities that our customers use to interact, onboard new customers, and provide approvals whenever a customer is onboarded."
- "The solution’s interface should be more user-friendly."
What is most valuable?
WSO2 API Manager provides OAuth2 token capabilities that our customers use to interact, onboard new customers, and provide approvals whenever a customer is onboarded.
What needs improvement?
The solution’s interface should be more user-friendly.
For how long have I used the solution?
I have been working with WSO2 API Manager for seven to nine years.
What's my experience with pricing, setup cost, and licensing?
WSO2 API Manager is an open-source solution.
What other advice do I have?
Recommending WSO2 API Manager to customers depends on their use cases. It's the customer's choice rather than our choice. WSO2 API Manager provides good support for API lifecycle management. We are satisfied with the solution and implemented it with one of the government organizations in India to deploy and manage their APIs. The solution's developer portal feature has improved the developer experience.
We charge our customers based on their IDs, secrets, the services they use, and how frequently they use them. We use WSO2 API Manager only for API management. We recommend the solution to customers based on their budget and whether they want an open-source solution or an open-source tool with technical support and minimal licensing cost.
The solution provides good documentation.
Overall, I rate the solution a seven out of ten.
