What platforms does Harbor run on?

Harbor runs everywhere you work, and every surface syncs through one account.

• Mac — a genuinely native SwiftUI app (no Electron), available from the Mac App Store or as a direct download with automatic updates.
• iPhone and iPad — one universal native app, with widgets, Siri Shortcuts, document scanning, Apple Pencil handwriting, and Face ID lock.
• Windows — a native app with x64 and ARM64 installers that update themselves.
• Android — a native Android app on Google Play.
• Web — a full offline-first app in your browser. It keeps a real database on your machine and installs as an app, so it works offline like the native ones. On Linux, this is how you run Harbor.
• Web Clipper — a browser extension for Chrome, Edge, Firefox, and Safari, all four at launch. See which browsers the clipper supports.
• CLI — the harbor command line puts the whole API at your fingertips, and it’s the foundation for bringing your own AI.

Whichever you pick, everything stays in sync — and everything works offline. Get the apps on the download page. If you’re comparing, here’s how Harbor’s platform list stacks up against eleven other notes apps, Linux gap included.
