SBOOK Go laptop running SmileyOS
Phase 1 · first version in stores in 2027

A computer for every kid.

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 idea

A new computer costs €500 to €1,000. A €20 one is enough.

Memory chips are in short supply, so every new computer gets pricier, while old computers sit unused because new systems no longer run on them. 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.

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.

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.

All the apps you need are already inside. For free.

Other systems give you the bare system and leave the rest to you: an office suite for documents and slides, design tools, music software, often as monthly subscriptions and big downloads. SmileyOS comes with all of it.

  • Every app is free, nothing extra to buy
  • No subscriptions
  • No big downloads
  • Plug and play from a USB stick or SD card
  • Take it with you: your desktop and your work stay on the stick

Word, PowerPoint, Illustrator, Figma and FL Studio are trademarks of their owners and are named only for comparison.

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.

Step 1 of 4

Your screen is made of tiny dots called pixels. A laptop screen with 1440 × 900 dots has almost 1.3 million of them.

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, to families and to schools. What that earns puts SBOOK Go and SBOX into production, and after them SBOOK. We start at home, in Macedonia and the Balkans, and then go wider in Europe. So we need all the support we can get.

  1. 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.

FAQ

Short answers.

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.
