Small native binary1
One tiny app, built for the Mac. Nothing running behind your back.
The real thing
No concept shots. This is the menu.
Every row below is rendered by the app from the live Polestar API — battery, range, charging state, odometer and service data, topped by a studio image of your exact car. Click the plate or VIN to copy them.
While charging, Polaris polls every minute and can notify you the moment the battery is full.

Why Polaris
Small. Native. Yours.
Charging notifications
A quiet nudge when charging starts, completes, or the charger reports a fault. Nothing else, ever.
Keychain, not plaintext
Password and session live in the macOS Keychain. Once signed in, Polaris resumes its session without logging in again.
Official API only
OAuth2/OIDC with PKCE against Polestar's own endpoints. No third-party servers, no analytics, no tracking.
Stays current
A once-a-day check against GitHub releases; when there's a new version, a menu item appears. No background updater.
Open source
MIT licensed, pure AppKit, no Electron, no SwiftUI, no background
services. make app and you have it.
The studio render of your exact configuration — paint, wheels and all —
fetched straight from Polestar and shown at the top of the menu.
Get started
Running in a minute.
No terminal, no Xcode — every release is a ready-built app. Download, drag to Applications and sign in with your Polestar account. Your VIN is in the Polestar app if it's not on hand.
Prefer to compile it yourself? Build from source is one command.
- Download Polaris.dmg and open it
- Drag Polaris into the Applications folder
- Open it — macOS blocks the first launch because the app isn't notarized yet. Click Done (not "Move to Bin"), then go to System Settings → Privacy & Security and click Open Anyway. This happens once. After that Polaris opens like any other app.
- Sign in — email, password, VIN
