MARS

MARS-Curiosity is an open-source Delphi library designed to simplify the development of REST servers and clients. It handles routing, parameter binding, JSON serialization, security, and OpenAPI generation, supporting both Windows and Linux platforms.

MARS sits in the Dev Tooling category, so it is usually better judged by workflow fit, deployment style, and team needs than by isolated features alone. Based on the available metadata, it leans most clearly toward Declarative REST resources and Express-style routing.. A representative use case is Building robust RESTful APIs for web and mobile applications using Delphi.. The listed license is MPL-2.0. GitHub stars are currently 400.
