WSO2 API Manager is used across the whole organization to expose the business entities on which 50% of all our applications are dependent on. We use it for our micro service infrastructure to connect and "loose couple" different application domains. It's main function is to provide a way to subscribe to API's and track API subscriptions.
  • Very easy to create API's: it has a very intuitive interface.
  • Overall (Subscriber and Store) everything looks clean and simple.
  • If you know how to, it provides you with all functionality that an API manager should provide. Like security, sandbox, API Console, swagger, mediation policies and much more.
  • Installation of this product is a hell. You need to be an expert to get this running together with WSO2 Analytics. It uses a really confusing method of "port + 1" to connect extra products. I guess this was meant to provide a handy way to add new WSO2 products. In reality you'll need to scroll through numerous config files to set this straight. If you use this out of the box, everything will work all right. But the moment you add SSL certificates, DNS names and you'll need special ports to configure your firewall, this product becomes unmaintainable.
  • The "Store" provides a nice way to group API's. However, the "Publisher" does not... if you have more than 30 API's searching for API's becomes really annoying.
  • The number of configs in this product is huge. As a developer myself, I've never seen (and definitely never created) a product that needed that much config files. Installation and maintenance of products should be stupidly simple, since no developer nor infrastructure person wants to learn something that "just" needs to be a tool.. opposed to being a whole new area of expertise. After using WSO2 API Manager for a while, we wanted to change the admin password... this should be simple enough, like just change the password in "Carbon." But nope. The whole WSO2 environment crashed. We just gave up. Too dangerous.
  • Why so many different "products"? Publisher, Store, Carbon, and numerous hidden interfaces. Analytics, ESB whatever... No wonder there are so many config files and port issues. Make it simple!!!
It's free! No argument can win a fight with that! And it's the only reason I gave it a 5. If you have no money to spend, and a simple environment you'll have a nice product. But free does come with a price. After 5 years we're still struggling with ports, and analytics (it just won't work without any errors caused by some configuration somewhere). An API Manager should work out of the box. The only configuration expertise that any developer wants to invest in, is the configuration of API's. Not the product itself... Anyone who've seen the training material, just for installing this thing will agree that this is not the way to go. Of all the API Managers out there (we've tried 4), WSO2 is the only one were you need to know how this dragon of a java application works internally. Did I already mention the humongous amount of config files?

WS02 has been used across our IT organization. We have been working to build the capability of APIs and manage the usage of APIs in a more seamless way across the enterprise. For the cost, WS02 API Manager is good for the usage we are using. We have encountered a fair amount of bugs with each upgrade of the product.
  • Nice API store-front capability
  • Management of users and permissions
  • Better QA testing prior to releases rollout
  • Better support needed
For smaller organizations, I think this is would be a good tool. For large enterprise organizations, WS02 API Manager is likely not the best fit.
