Overview
Arc puts the information you actually check — time, weather, markets, notes, focus —
directly on your desktop. No browser tabs, no app switching. Just a glance.
We built Arc because most widget apps are heavy, closed, or platform-locked.
Arc runs on Tauri 2, so it works natively on Windows, macOS, and Linux with a small
memory footprint. Every widget is draggable, lockable, and arranges automatically —
your desktop stays clean without manual fiddling.
Built-in Widgets
Clock & Calendar — glanceable time, with optional Jalali (Persian) calendar
Weather — live conditions without opening a tab
Crypto — market prices, always visible
Notes — quick capture that lives on your desktop
Pomodoro — protect your focus sessions
Workspace Controls
Show, hide, arrange, and lock widgets from the system tray. Dark, light, or follow
your system theme. Launch at startup if you want it always there.
Open Source, Private by Design
Arc is MIT-licensed. No accounts, no telemetry — your notes and settings stay on
your machine. Read the source, audit it, or contribute on GitHub.
Download
Prebuilt installers are on the Releases page —.msi for Windows, .dmg for macOS, AppImage / .deb for Linux.
Or build from source: github.com/ahuryx/arc.
