About OpenBucket
OpenBucket opens S3 buckets like folders on your Mac: grid and list views, thumbnails, Quick Look, an Info panel with headers, tags and photo details, version history, presigned share links with a QR code, and parallel downloads and uploads. A Storage Overview maps a folder by size and kind, and Compare with Local Folder checks a local copy and can update either side without deleting anything.
Every connection is read-only until you turn on Allow changes for it, and keys you enter are kept in the macOS Keychain. It works with custom endpoints, path-style addressing, AWS CLI profiles and buckets your key can't list. It is an early release that needs macOS 26 or later; the project documents which providers have been tested live (Garage and S3Mock so far) and is published by Koative, the team behind this catalog.
