Doors 11 is a small, virtual operating system inspired by Windows 11 in its interface and name. It was developed as a personal project for the purpose of fun and learning programming. Doors 11 uses Chromium as its base, and it runs virtually without real hardware. Doors 11 is primarily designed to meet the needs of the developer himself as a demo platform, where the developer can use it as a reference while designing real systems on real hardware in languages such as C, C++, or ASM.

Doors 11 is a project aimed at fans of software experimentation and creative projects, as well as interested programmers. However, Doors 11 is not a traditional development environment and no one can develop complex applications on it, unless they have simple HTML skills, as they can develop simple programs that run on Doors 11 only. Doors 11 is effective in providing users with a fun and exploratory experience of programming and virtual systems, and may interest programmers eager to explore small systems and simple projects.
