 # Native REST Support
 Restlet Framework provides a reusable and extensible set of classes and interfaces that serves as a foundation on which you can construct your own web applications more efficiently. Aligned with the REST and HTTP concepts and terminology, the Restlet API can be used for both client and server-side development. Using the same Java API which reduces both the learning curve and the software footprint and facilitate the development of applications acting as server and client at the same time.

 # Secure and Scalable
 You should never have to make a tradeoff between security and scalability for your APIs. Restlet Framework supports standard security and authentication methods. A fully multi-threaded design with per-request resource instances reduces thread-safety issues, and ensures that APIs will scale no matter how many requests.

 # Broad Use Case Support
 APIs you build with Restlet Framework can be deployed to all common environments. An extensible set of representations, support for standards, and numerous connectors lets you build and call any type of web API, and connect to any backend process or data source.
