What it does

One window, every folder.

The Finder is fine for one folder at a time. Trellis is for the rest of the day.

▥

Up to nine panes

Split a window into two to nine panes, drag the dividers, and keep the folders you compare side by side.

⇥

Tabs and workspaces

Keep tabs in every pane and save the whole layout as a named workspace you can return to in one click.

⇅

SFTP built in

Browse a remote folder like a local one, upload and download with progress, and reconnect quietly when the network drops.

⇄

Moves between panes

Copy or move files across panes — local or remote — without dragging through the Finder.

≟

Folder comparison

Compare two folders by size and modification time, see what differs, and copy only what you choose. Nothing is deleted.

⌘

Finder-aligned

Delete, Get Info, cut and paste, label colors, and keyboard shortcuts behave the way Finder users expect.

In development

Still in development.

Trellis has not shipped yet. It is being prepared for the Mac App Store; a release date and price will be announced when they are final.

This page describes the app as it stands today. Features may change before release.
