Delphi combines Object Pascal with a visual component library for rapid native application development. It compiles to native binaries for Windows, macOS, iOS, Android, and Linux from a single codebase. Despite low visibility in open-source communities, it has a large installed base in healthcare, finance, and logistics applications, many of which have run continuously for decades.
