Arqo for your desktop.
The same editor you use on the web — in a native app that opens in under a second, works without wi-fi, and lives in your dock or taskbar. No browser tab, no logging in through a studio's IT system.
One-line install · macOS Apple Silicon
curl -fsSL https://tryarqo.com/install-mac.sh | bashPaste into Terminal.app, hit return. Downloads the .dmg, copies into /Applications, removes Gatekeeper's quarantine flag, launches. Read the source first if you'd rather — /install-mac.sh.
Or download manually:

Install steps
Each platform has one extra step on first launch — macOS strips the quarantine flag with xattr, Windows clicks past SmartScreen. Both retire once we have signed builds.
macOS · Apple Silicon
- 01
Download the .dmg
Apple Silicon button above. ~42 MB.
- 02
Drag to Applications
Open the .dmg, drag Arqo.app into your Applications folder, eject.
- 03
Strip quarantine + open
macOS will refuse the unsigned bundle. Run the xattr command below once, then double-click normally.
If macOS says "Arqo is damaged" — it's not. Strip the browser-stamped quarantine flag and reopen:
xattr -dr com.apple.quarantine /Applications/Arqo.appWindows · x64
- 01
Download the .msi
Windows x64 button above. ~55 MB. WebView2 ships pre-installed on Windows 11; Windows 10 1809+ installers fetch it on first run.
- 02
Run the installer
Double-click. Walks through the standard Windows Installer flow into Program Files.
- 03
More info → Run anyway
SmartScreen will warn (the binary isn't yet EV-signed). Click "More info" then "Run anyway." Subsequent launches skip it.
Microsoft Defender / corporate AV may quarantine the .msi until it sees the binary a few hundred times. EV-signed builds clear this on day one — that's the next step in the signing roadmap.

Intel Mac (x86_64) and Linux aren't shipped yet — universal-binary macOS lands once we have an x86_64 Bun runtime; Linux is on demand (open an issue if you want it). Until then, the web app at tryarqo.com/app is the same editor — every feature parity-tested, no install required.
