DreamFactory is described as 'We instantly generate APIs from services (MySQL, MS SQL, Oracle, IBM DB2 + more) and datasources, automate manual processes, and expose key data from legacy sources (SOAP to REST), and allow for end-to-end operational efficiency and transparency' and is an app in the Development category. There are four alternatives to DreamFactory for a variety of platforms, including Linux, Mac, Online / Web-based, Windows and Self-Hosted solutions. The best alternative is Kong, which is both free and Open Source. Other great apps like DreamFactory are Tyk (Free, Open Source), WSO2 API Manager (Free, Open Source) and Apigee (Freemium).
Kong is a scalable, open source API layer (also known as a API gateway, or API middleware). Kong runs in front of any RESTful API and is extended through plugins, which provide extra functionalities and services beyond the core platform.
