Bucket Explorer for B2

Bucket Explorer is a native Mac app for Backblaze B2 Cloud Storage. Browse your buckets like folders in Finder, upload by dragging files in, and share a link in a click.

BROWSE • Tabs, a sidebar of favorite folders, and search across subfolders • Quick Look and text previews before you download • Rename, move and create folders, or drag files onto a folder to move them • Create public or private buckets

UPLOAD FROM ANYWHERE • Drag files into any folder, including very large files, which upload in parts • Menu bar companion: drop files on the icon, upload the clipboard, and get back to recent uploads • Right-click files in Finder, or text and images in other apps, and choose Upload to Bucket Explorer from the Services menu • Watched folders: files added to a folder on your Mac upload by themselves to the bucket folder you choose

SHARE • Copy a link as soon as an upload finishes • Plain links for public buckets, and links that expire after a day for private ones

VERSIONS AND STORAGE • See every version of a file, then download or restore an older one • Clean up old versions across a bucket, with a preview of what will be removed and how much space it frees • A storage overview shows what each bucket holds, including the old versions and unfinished uploads you are still billed for

COMMAND LINE AND AI AGENTS • The bex command-line tool lists, uploads, downloads and links files using the app's sign-in • An included agent skill lets AI coding agents work with your buckets through bex

PRIVATE BY DESIGN • Your application key is kept in your Mac's keychain • The app talks directly to Backblaze, with no servers in between and no tracking

Requires a Backblaze B2 account and an application key.
