Fusio is an open source API management platform which helps to build and manage RESTful APIs. We think that there is a huge potential in the API economy. Whether you need an API to expose your business functionality, develop One-Page web applications, Mobile-Apps or Microservices. Because of this we think that Fusio is a great tool to build such APIs. If you like the project and want to see it grow please report any issues or simply drop us a line.
If you are researching API solutions you probably hear often the term API-Gateway/Proxy and API-Management. Fusio is an API-Management system in the sense that it helps to develop actual API endpoints (which i.e. request and transform data from a database). It is not limited to proxy requests to another API. The following diagram should give you a better overview where Fusio is placed in the tech stack.
Fusio uses the backend services to produce the API response or to handle the request data. A backend service can be a database, message queue or another API. It is also very easy to implement a custom connection to support any kind of service.
Exposing an API of your business functionality is a great way to extend your product. You enable customers to integrate your business value into other applications which gives the possibility to open up for new markets. With Fusio you can build such APIs and integrate them seamlessly into your product. We also see many companies which use the API itself as the core product.
With Fusio you can simply build small micro services which solve a specific task in a complex system.
Almost all mobile apps need some form to interact with a remote service. This is mostly done through REST APIs. With Fusio you can easily build such APIs which can also be used by other applications.
