ArashOS

Tour

A tour of ArashOS

Kaman, the desktop made for ArashOS, part by part, and the 13 themes it comes in. Pick a theme below to see the desktop in it.

Kaman, the desktop

Kaman means the bow. It's the desktop ArashOS draws around your windows: the bar, the launcher, notifications, the lock screen, App Center and Settings, made in one style. A menu loads when you open it, and the desktop does no work while you aren't using it.

The wallpaper in these screenshots is “The Feast of Sada”, a page of Shah Tahmasp's Shahnameh painted about 1525 and attributed to Sultan Muhammad, at the Metropolitan Museum of Art, in the public domain.

Wallpaper: The Feast of Sada, The Met, public domain.
The welcome on its App Center page, page 2 of 9: what App Center is, how it keeps you safe, and the kinds of apps it has.

The welcome

It opens the first time you sign in. Its pages show App Center, the themes, the AI you can turn on, how an update can be undone, the safety steps and the keys worth knowing first. Skip it, or open it again later by typing Welcome in Tir.

Wallpaper: The Feast of Sada, The Met, public domain.
The bar down the left side of the screen, with the calendar for November 2026 open beside the clock.

The bar

A thin bar down the left side, joined to a frame around the screen. Point at an icon and its menu grows out of the bar: Wi-Fi, Bluetooth, sound, the battery, the calendar. Settings can move the bar to any edge and change what it shows.

Wallpaper: The Feast of Sada, The Met, public domain.
Tir with “night” typed: the settings “By night”, “Night starts” and “Follow the clock”, and the Appearance page, each with where it is in Settings.

Tir, the launcher

Tap the Super key, the one with the Windows logo, and Tir, the arrow, opens out of the bar. Type a few letters of an app, a page in Settings or a single setting, and press Enter. It works out sums too, and with nothing typed it shows the apps you use most.

Wallpaper: The Feast of Sada, The Met, public domain.
The notifications list open from the bell on the bar: Do not disturb, and notifications from Firefox, Dolphin and Kate, grouped by app.

Notifications

They appear in the top corner away from the bar, and go after five seconds. The ones you missed wait behind the bell on the bar, grouped by app. Do not disturb holds them all back, except urgent ones.

App Center on All apps: categories down the side, and the Development apps, VS Code, Zed, Neovim, Docker, Podman and GitHub CLI, each with Install.

App Center

One place to install the apps you'll want next: browsers, messengers, office, graphics, games, development, AI and more. Each app is set up after it's installed, so you rarely need a terminal. Installing or removing an app asks for your password each time. Open it with Super + Alt + Space.

Settings on the Appearance page: its groups down the side, and the 13 themes as small pictures of the desktop, the one in use marked.

Settings

Seven groups, from Personal to Safety, every page in the same ruled style. Search finds a single setting, not only its page, and takes you to it. Settings for experts stay out of the way until you ask for them.

The Updates page in Settings after a check: one firmware update waiting, which a snapshot can’t undo, with Update, and the switches for update notices and AUR apps.

Updates

The Updates page in Settings checks for new versions of ArashOS and your apps, and installs them. A snapshot is taken before and after, so an update can be undone, and your files aren't touched. You can close Settings while it runs: the computer won't sleep or shut down until it's done.

Wallpaper: The Feast of Sada, The Met, public domain.
The lock screen: a large clock, the date, the ArashOS picture and name, and the password field.

The lock screen

A large clock and the date, your name and picture, and the password field, with your fingerprint where the computer has a reader. It never shows notifications, and other screens show only the time.

Thirteen themes

Each theme takes its colours from something Persian. Pick one to see the desktop in it. On ArashOS, Settings › Appearance changes the theme at once.

The theme for the drawing

Dark theme

Lajvard لاجورد

A lapis night with gold borders, like the margins of an illuminated manuscript. The default dark theme.

Light theme

Kaghaz کاغذ

The page of a manuscript: parchment and ink, with lapis for buttons and links and gold ink for highlights. The default light theme.

Dark theme

Banafsheh بنفشه

Dusk in the garden after the violets close: plum and violet, with gold.

Light theme

Darya دریا

The Caspian on a grey morning: mist over the water, coral and shells on the shore.

Dark theme

Kavir کویر

Dunes in shadow under the clearest stars in Iran, and the last warm light on the sand.

Light theme

Firouzeh فیروزه

The turquoise and cobalt tiles of Isfahan at noon, on white, set in buff mortar.

Dark theme

Sarv سرو

A Persian garden at night: dark cypresses, water channels catching the sky, roses along the paths.

Light theme

Golestan گلستان

The rose garden, after Saadi's book: blush and rose, with the green of the leaves.

Dark theme

Yalda یلدا

The longest night of the year, kept awake with pomegranates, candles, pistachios and Hafez.

Light theme

Kahgel کاهگل

The adobe walls of Yazd and Kashan, and the cool shade under their windcatchers.

Dark theme

Zoghal زغال

The coppersmiths' bazaar: charcoal grey, copper and steel. The quietest theme, for those who want little colour.

Light theme

Nowruz نوروز

The new year's first day of spring: sprouting wheat, hyacinth, and a goldfish in its bowl on the haft-sin spread.

Light theme

Zafaran زعفران

The crocus fields of Khorasan in October: lilac petals around the red-gold threads of saffron.

The drawing shows the bar, the Settings window and a notification, in each theme's own colours, made from the same files ArashOS uses. The page itself stays in Lajvard or Kaghaz, as your computer's light or dark setting asks.
