About

What is red?

Red is a powerful, next-generation programming language inspired by Rebol, designed for a broad range of applications from system programming to high-level scripting and cross-platform reactive GUI development. It features a native-code compiler, enabling the creation of small, dependency-free executables (less than 1MB). Red supports modern concurrency and multi-core CPUs, and utilizes a DSL-oriented approach with built-in dialects like Red/System for C-level programming, Parse for PEG parsing, VID for GUI layout, and Draw for 2D vector graphics. The toolchain is self-contained, offering an encapper, compiler, interpreter, and linker, all within a single, zero-install file. It supports cross-compilation to various platforms including Windows, Linux, macOS, and Android, making it highly versatile for developers.

Best used for

Ideal for developers who need to build efficient, native applications, create cross-platform graphical user interfaces, and perform low-level system programming. Especially valuable for those requiring a self-contained, zero-install toolchain that produces small, dependency-free executables and supports concurrency.
