Redox is a Unix-like microkernel operating system written in the programming language Rust, a language with focus on safety and high performance.[2][3][4] Redox aims to be secure, usable, and free. Redox is inspired by prior kernels and operating systems, such as SeL4, MINIX, Plan 9, and BSD. It is similar to the GNU or BSD ecosystem, but in a memory safe language and with modern technology.[5] It is free and open-source software distributed under an MIT License.


The Redox operating system is designed to be highly secure, and this is reflected in several design decisions such as:


Redox is a full-featured operating system, providing packages (memory allocator, file system, display manager, core utilities, etc.) that together make up a functional and convenient operating system. Redox relies on an ecosystem of software written in Rust by members of the project.

  • Redox kernel – largely derives from the concept of microkernels, with heavy inspiration from MINIX
  • Ralloc – memory allocator
  • TFS file system – inspired by the ZFS file system
  • Ion shell – the underlying library for shells and command execution in Redox, and the default shell
  • Magnet – package manager
  • Orbital windowing system – display and window manager, sets up the Orbital: scheme, manages the display, and handles requests for window creation, redraws, and event polling

Command-line applications[edit]

Redox supports command-line interface (CLI) programs, including:

  • Sodium – vi-like editor that provides syntax highlighting
  • Rusthello – advanced Reversi AI; is highly concurrent, serving as proof of Redox's multithreading abilities; supports various AI strategies, such as brute forcing, minimax, local optimizations, and hybrid AIs

Graphical applications[edit]

Redox supports graphical user interface (GUI) programs, including:

  • Browser – simple web browser with basic image support[6][7]
  • Calculator – a software calculator which provides functions similar to the Windows Calculator program
  • Editor – simple text editor, similar to Microsoft Notepad
  • File Browser – a file manager that displays icons, names, sizes, and details for files; uses the launcher command to open files when they are clicked
  • Image Viewer – simple type
  • Pixelcannon – 3D renderer, can be used to benchmark the Orbital desktop
  • Terminal Emulator – ANSI type, launches Bourne shell (sh) by default


Redox was created by Jeremy Soller and was first published on 20 April 2015 on GitHub.[8] Since then, it has been developed actively, with contributions by over 40 developers.[9] On the second anniversary of Redox appearing on GitHub, version 0.2.0 was released.
