Coming Soon

Two-Pane Browser

Local files on one side, your B2 buckets on the other — or any combination. Upload, download, and copy with drag and drop.

Built for Big Transfers

A transfer queue that handles thousands of files, resumes interrupted uploads and downloads, and survives an app restart.

Compare & Versions

Compare a local folder against a bucket before you copy, and browse, restore, or download older versions of any file.
