Why Buckotto

Built for R2,
not adapted to it.

Generic tools treat R2 like any other bucket — and that's exactly where they break.

Uploads that actually finish

Many Mac transfer apps stream uploads in a form R2 rejects, so big transfers die mid-flight. Buckotto uploads exactly the way R2 expects — fixed-size parts, known lengths, crash-safe resume.

Fast where others crawl

Generic S3 tools page through huge buckets one slow request at a time. Buckotto paints the first screen of any bucket from a single request and scrolls 100,000+ objects at 60fps.

More than the dashboard

The web dashboard caps uploads at 300 MB and has no search or bulk operations. Buckotto has no size ceiling, searches the whole bucket locally, and batch-renames, copies and deletes.

Trust

Private by design.

There are no Buckotto servers — by architecture, not by promise.

Your keys stay home

Credentials live in the macOS Keychain, encrypted by your Mac — never in a config file, never uploaded. Revoke the token in Cloudflare and Buckotto is instantly blind.

No middleman, no telemetry

Every request goes straight from your Mac to your R2 endpoint over TLS. Nothing passes through our servers, because there aren't any — and nothing about your data is phoned home.

Local index, minimal egress

Search and thumbnails run on an index stored on your Mac, so browsing doesn't rack up API calls or egress. Least-privilege, object-scoped tokens work fully.
