Zephyr Makes Dropbox Behave Like a Mac Citizen

zephyrmac.app Observed source

Editorial interest 84/100 Selection signal · not a rating of the site

An open-source Dropbox client for macOS that integrates with Finder, the share sheet, the menu bar, widgets, and a command-line tool.

Landing page captured for the 2026-09-16 issue.

Field notes

Zephyr uses macOS's replicated File Provider so Dropbox accounts appear in Finder and files remain off the local disk until opened. Its Swift-based components share one syncing framework across the menu-bar app, Finder extension, share sheet, widget, and command-line tool. The page specifies resumable uploads for files over 4 MiB, content-hash verification in both directions, and previews for six image formats up to 20 MB.
