What is Bucketree?
Native Mac management for Backblaze B2 buckets, keys and file operations. Bucketree: B2 administration with a Mac front door Bucketree is a native Mac file manager for Backblaze B2, published by MacUpp, a Web Upp Limited brand.
Why we recommend it
A focused option for Mac-based B2 users who want files, versions, keys and lifecycle work together. The native interface and detailed documentation look useful, but compatibility is narrow and destructive actions remain the user's responsibility. Our 3.9/5 desk-research score is provisional, not a hands-on endorsement.
Best for
- Apple silicon Mac users with B2 buckets
- B2 administrators
- small studios managing files and version cleanup
Key features
Browse multiple accounts, buckets, current files, versions and hide markers in a Mac interface.
Upload/download with checksum handling and Quick Look previews.
Search names, extensions, sizes, dates and version states across buckets; listing walks take time.
Copy or move objects between buckets without routing the object data through the Mac.
Create, scope and revoke keys; controls reflect the supplied key capabilities.
Pros
- Genuine native UI with file, key and bucket-policy workflows.
- Three-Mac licence and ten-Mac annual team option; no feature-tier upsell.
- 30-day no-card trial; read/download access remains after expiry.
- Detailed official docs explain B2 hide markers, lifecycle clocks and irreversible actions.
Cons
- Requires macOS 26+ on Apple silicon and a B2 account/key; no Intel, Windows, mobile or general S3/R2/Wasabi support.
- Deleting all file versions is permanent and enabling Object Lock cannot be undone; keep independent backups and least-privilege keys.
- Backblaze storage/extra egress are separate; scans are not a live bill, and console-only reports/caps/snapshots remain outside the client.
- Keychain/file-to-B2 claims do not mean zero vendor traffic: update/licensing data reaches vendor/Freemius; security/performance untested, MCP coming soon.
