MARS-Curiosity REST Library
MARS-Curiosity (MARS in short) is an open source REST library for Embarcadero Delphi. Lightweight yet powerful and easy to extend, it enables Delphi developers to easily build REST server applications (on all supported platforms including Windows, Linux, OS X and mobile platforms) and REST client applications (through the included MARS Client Library). The generated server and client applications can be used across different REST technologies but retaining the advantages of a Delphi to Delphi scenario.
