How to Make an "OS"

What is an OS and how do you make one? Here are all the basics for mimicking an OS.

Author's Note: This blog post will not teach you how to make a real Operating System! It will only teach you how to make a program that looks like and has the format of one. This blog post is outdated and was created during the OS-craze on a beginner's programming website called Scratch. 

An OS is an operating system that manages a computer. It lets you log in, organize programs and a lot of cool, useful things. Common operating systems include Windows and Mac.

A lot of people on Scratch like to make an OS because it is a great way to showcase design.
For example, here is Fiber OS 5.1 by N25Games.



For an example of a very basic OS, check out my project Orange OS.

A high-quality OS is:

1. Easy to use and navigate
2. Simplistic and clean graphics that contribute to the UI and UX
3. Very useful and has multiple apps/programs (common programs include games, drawing, messaging, reading, searching, and music)
4. Full of smooth transitions

The main features are the logo, loading screen, lock-screen and/or log in page and apps.


You can draw inspiration from any computer. Most will have decent design and transitions you can base yours off of.

Tips: Using real images (preferably blurred) as backgrounds make your OS look professional.

Here is a compilation of multiple great user interface examples. Notice how each section is clear and easy to use. Common symbols convey meaning without making the user read too much.



Basic apps commonly already downloaded on an operating system include Notes, Internet, Photos, Videos, Settings, Calculator, Time, and Calendar. Be creative and add your own apps as well, such as music or a game.
