Native
Real apps, not a web page in a wrapper.
Harbor is built native for each platform — SwiftUI on Apple devices, native on Android — for speed and battery life. The opposite of a sluggish Electron rebuild.
Offline
Works with no signal.
Browse, edit, even search offline — on the plane, at the cabin, in the parking garage. Everything syncs the moment you're back, with conflict copies instead of silent overwrites.
Web too
A real app in your browser.
The web app keeps a real database in your browser, so even harbor.my works offline and stays fast with years of notes. Install it like an app; it behaves like one.
Desktop superpowers
Made for power users.
Tabs, multiple windows, a global quick-capture hotkey, Spotlight and Handoff on the Mac, widgets and Siri shortcuts on your phone. Harbor meets each platform where it lives.
Your library can grow for decades without filling your disk — Harbor syncs down only what you need, and fetches the rest on demand.

Anchored. Private. Yours.
Fast everywhere you are.
Download Harbor on every device you own — one account, one brain, always in sync.
