SmileyOS is an operating system made for kids and simple enough for anyone. It is so small that a computer 10 or 20 years old, the kind that costs about €20, or a Raspberry Pi runs it from a small USB stick or microSD card. Nothing to install, nothing to break.
The laptop on this page is SBOOK Go, the computer we are designing for it. Every picture on its screen is a real screenshot of SmileyOS. We are looking for investors and partners for Phase 1.
A new computer now costs €500 to €1,000. Ours start at about €50.
Memory chips are in short supply, and the price of every new computer goes up with them. Many families cannot spend that on a first computer for their child.
Old computers cost almost nothing, but new systems no longer run on them.
So they sit unused, at home and in schools.
And the computers kids do get run big systems made for grown-ups, with ads, feeds and an open internet.
SmileyOS is built for speed and efficiency, so a computer for €50 to €250 can feel as quick as a €2,000 one. That is the computer we are building.
The idea
A €20 computer is enough.
SmileyOS is tiny, so it is fast. It runs on a computer that is 10 or 20 years old, the kind you can buy used for about €20, and on a Raspberry Pi.
What is on a 100 MB stick
System20 MBStorage72 MB
With SmileyOS, a computer that is 10 or 20 years old feels like it was bought yesterday.
How it starts
Plug in the stick. Turn on the computer.
SmileyOS starts straight from the USB stick or SD card. Nothing is installed on the computer.
Nothing to install, so there is nothing to break.
Your work is saved on the same stick.
Simple mode
Big tiles for the youngest and the oldest.
Not everyone needs a desktop. Simple mode turns the screen into big, colorful tiles that a five-year-old or a grandparent can use from the first day.
The same apps and the same files as the desktop.
Works with the keyboard alone, the mouse alone, or both.
What is inside
Everything a kid needs is already inside.
Those 100 MB hold a complete system with 20 built-in apps and games, all designed together, and our own App Store brings more. It takes a child from the first click to the first game, and it does the everyday work of anyone: documents, files, music and the web.
Learn
Learning that feels like play.
From counting on fingers at five, to flying between the planets.
Create
Tools to make real things.
Writing, drawing, slides and music are part of the system.
Classroom
A whole classroom, connected. No server needed.
It works on the computers a school already has. Computers in the same room find each other, with no internet and no accounts. And a class can also meet online, from home.
Class chat, raised hands and quick polls
Quizzes with live scores for the teacher
The teacher can pause the chat and pin a message for everyone
Students show their code or slides live to the class
Online rooms with a code and a PIN, when parents allow it
Play
Games that belong to it.
Every game is made for SmileyOS. Even the 3D racing game is drawn by the processor alone, so it runs on old computers. Snake, Strike and Turbo can also be played with friends in online rooms. No ads and no in-app purchases.
Internet and AI
The internet and AI, only as far as parents allow.
SmileyOS works fully offline. The internet and the AI helper are on only when a parent or a teacher decides so.
A kid-safe browser. Searches open encyclopedia articles, and parents choose the allowed websites.
An AI helper that answers for the age of the child. One switch turns it off everywhere.
Online rooms for classes and games only when a parent turns them on.
No ads, no feeds and no tracking anywhere in the system.
SBOOK Go
SBOOK Go, a laptop of our own.
Not every family has an old computer at home, so we are building one: SBOOK Go, the laptop on this page, built around SmileyOS from parts you can buy. Made for kids, simple for anyone. Its first prototype is in the making, and it goes into production with SBOX once the stick and the card have earned enough. The more powerful SBOOK comes after them.

What would you pay for SBOOK?
Your answers shape the hardware.
We are a small startup, so your feedback means a lot to us. If most people pick a lower price, we look for cheaper parts and keep what matters most. If many people want SBOX, it moves up the list.
We aim for €50 to €100 for SBOX, €150 to €200 for SBOOK Go and €200 to €250 for SBOOK. The final prices come after the prototypes, from your answers.
Your answers stay anonymous unless you join the list.

Where we shine
Big companies go bigger. We go the other way.
Every new Windows and macOS needs more memory, more space and a newer, more expensive computer. Linux is free, but Ubuntu 26.04 now asks for more memory than Windows 11. SmileyOS goes the other way: small, simple and quick, with cheap computers built around it.

Updates with a way back
A new version is written next to the one that runs, never over it. The computer tries it once; if it does not start, the previous version starts by itself. The factory version is always kept.
Others: Windows, macOS and most Linux systems change the system in place, so a bad update is hard to undo.
20 MB, not 64 GB
The whole system, with its 20 built-in apps and games, is about 20 MB. More come from our own App Store.
Others: Windows 11 asks for 64 GB of space, Ubuntu Linux for 25 GB.
256 MB of memory, not 4 to 8 GB
SmileyOS runs with 256 MB of memory, so old computers are enough.
Others: Windows 11 needs 4 GB, Ubuntu 26.04 needs 6 GB, and the cheapest Mac has 8 GB. Memory is what makes computers expensive now.
Quick on old processors
A computer that is 10 or 20 years old feels like it was bought yesterday. Every part is written for weak hardware: even the 3D racing game is drawn by the processor alone, and Fast mode turns the effects down on the slowest computers. Now SmileyOS also starts every core of the processor and shares the work between them.
Others: Big systems slow old computers down until they are put away.
One look, made with care
The desktop and the 20 built-in apps are designed together, in one modern look, and apps from our own App Store are made with the same parts through our App SDK. Dark or light, accent colors and 22 wallpapers make it yours.
Others: Linux mixes many desktops and looks. Windows and macOS are made for grown-ups.
€20, not €800
A used PC or a Raspberry Pi runs SmileyOS, and our own computers are built around it, from about €50 to €250.
Others: The cheapest Mac costs €799. Windows 11 needs a TPM 2.0 chip and a newer processor, so most older PCs cannot run it.
Where things are, side by side.
Every big system has a bar, a place for the apps and a search. SmileyOS has the same, so the habits a kid learns here carry over to them. And it adds Simple mode for the youngest.

Maybe I aim too high when I put SmileyOS next to Apple, Microsoft and Linux. But the numbers and the facts stand their ground. Behind Windows and macOS stand some of the biggest companies in the world. Behind SmileyOS stands one dreamer. And when you dream, only the sky is the limit.
Nikola GjorgievFounder of SmileyTech
It is this small because every part is ours.
We did not shrink a system made for grown-ups. We wrote a new one for kids, with only what a kid needs.
01
Our own system
SmileyOS is written from the first line, with nothing in it that a kid does not need. That is why it is about 20 MB, runs with 256 MB of memory and stays quick on old computers.
02
Our own apps and lessons
Tools, games and learning content are designed together, in the language the child speaks. All of them come with the system, and more come from our own App Store.
03
Our own language
Smilium is made for a first line of code, and it grows into real programming.
04
Our own computers
SBOOK Go, SBOX and SBOOK are cheap computers built around SmileyOS, for families, schools and anyone who wants a simple computer. SBOOK Go and SBOX come first, SBOOK after them.

The business
How it becomes a business.
Four ways SmileyOS earns. We start at home, in Macedonia and the Balkans, and then go wider in Europe.
Families
SmileyOS for home
On a USB stick for an old PC or a microSD card for a Raspberry Pi, with its learning books.
Schools
SmileyOS for schools
Classroom packs and licenses for schools, coding clubs and learning programs.

SBOOK Go, SBOX, SBOOK
Our own computers with SmileyOS built in: SBOOK Go and SBOX once the stick and the card pay for their production, then the more powerful SBOOK.
Subscription
AI helper plan
An optional, kid-safe AI helper, paid by parents or schools.
The plan
One step pays for the next.
To be open about it: first we sell SmileyOS on a USB stick for old computers and on a microSD card for the Raspberry Pi. What that earns puts SBOOK Go and SBOX into production, and after them SBOOK. So we need all the support we can get.
2025 to 2026Done
A working system
From the first line of code in 2025, one founder on nights and weekends, to a desktop, 20 built-in apps and games, a classroom and three languages on real computers.

The dreamThe dream
Into schools, and into prisons
SmileyOS in every primary school in Macedonia, and then further. And in prisons: a safe, controlled computer where people can learn skills for a new start.
Nikola Gjorgiev has built software since 2014: mobile games first, then apps for mobile, web and desktop. He designed and wrote SmileyOS from the first line: the system, the language, the apps and the games.
This is my plan and my wish. I am a big dreamer, and I believe in this story.
SmileyOS started as one developer's nights and weekends. We are now registering SmileyTech as a company, and we are looking for the people who want to build it with us.
Investors and grant-makers
Back the first version.
We are raising for Phase 1: the first version of SmileyOS in stores, the learning books, and the first SBOOK Go prototype. Ask for the plan and the numbers.
A complete operating system made for children, and simple enough for anyone. It has its own desktop, 20 built-in apps and games, its own App Store with more, a classroom mode, and Smilium, a programming language for beginners. For a child it is one safe place to learn, to create and to write code; for everyone else it is a simple computer for documents, files, music and the web. It is about 20 MB and runs with 256 MB of memory, so a computer that is 10 or 20 years old or a Raspberry Pi is enough.
