What is KAIRO Cloud OS?
KAIRO is an operating system you open in a browser tab. The computer it runs on lives in the cloud, so what you can do no longer depends on the device in your hands.

The basics
The browser is the gateway. The cloud is the computer.
- What it is
- A remotely hosted computing environment with a desktop-style interface, reached through any modern web browser.
- What it is not
- It is not an app to download and it does not replace the operating system on your device. It runs alongside it, in a tab.
- Who it is for
- People who want to learn, build, or ship software without being limited by the hardware they own.
How it works
From a browser tab to a working computer
Open a browser
Go to KAIRO and sign in. There is nothing to install on your device.
Start a workspace
A workspace is your own isolated computing environment, started for you on remote infrastructure.
Get to work
Use the terminal, manage files, and write code. The processing happens in the cloud; your device shows the result.
Come back later
Workspaces are designed to persist. Close the tab and pick up where you left off.
What is what
The parts of KAIRO, in plain terms
KAIRO uses a few names you will see throughout the product. Here is what each one means and what it is for.
- Workspaces
- Your computing environments. Each one is isolated from everyone else's and can be created, started, stopped, and removed.
- Desktop
- The interface you see in the tab: windows, a dock, and a top bar, arranged like a familiar desktop.
- Terminal
- A command line connected to your workspace, for running commands and tools directly.
- Files
- A file manager for browsing, creating, editing, and deleting what is stored in your workspace.
- Code editor
- An editor in the browser with syntax highlighting and a file explorer.
- Git
- Version control built in: clone repositories, commit, branch, push, and pull.
The difference
How it differs from the computer you already have
| A typical computer | KAIRO Cloud OS | |
|---|---|---|
| Where the computing happens | On the device in front of you | On remote cloud infrastructure |
| What your device needs | Enough power for the work itself | A modern browser and a connection |
| Setting up | Install and configure tools locally | Sign in from the browser |
| Switching devices | Your work stays on that machine | Your workspace is where you left it |
Questions
Common questions
Do I need to install anything?
No. KAIRO runs in a web browser. You sign in and work from a tab.
Does it replace the operating system on my device?
No. Your device keeps its own operating system. KAIRO is a separate environment in the cloud that you open from it.
What do I need to use it?
A device with a modern web browser and an internet connection. Because the computing happens remotely, KAIRO needs a connection to work.
What happens to my work when I close the tab?
Workspaces are designed to persist, so you can close the browser and return to the same environment later.
Is KAIRO available now?
Not generally. KAIRO is still in development. You can see a video walkthrough and screenshots of the current build on thekairo.dev, where access is also announced.
