Business applications created on the Cloudfier platform inherently contain an API that grants full access to app functionality through the Cloudfier API. Cloudfier allows users to define a business centric solution with Cloudfier’s business programming language. After the solution is defined, the platform automatically creates a web application. Cloudfier was built on Elipse Orion and aims to move towards a new type of development.
MuleSoft has released a parser and Visual Studio extension for its Anypoint Platform that aim to give developers the ability to more easily work with APIs using RAML. RAML is the RESTful API Modeling Language originally based on YAML, that allows developers to document APIs in a human-readable form.
