Multi-provider

AWS S3, Cloudflare R2, MinIO, Backblaze B2 and any S3-compatible endpoint. Save as many connection profiles as you need.

Bucket browser

Folder navigation, breadcrumbs, multi-select, drag-and-drop upload and recursive download. Filter and sort by name, size, class or date.

Transfer queue

Every upload, download and copy tracked in a bottom dock. Cancel running transfers or retry failures individually.

Cross-provider copy

Copy files and folders between buckets on different providers. Pick a destination and prefix; BucketDock handles the rest.

Inline preview

Open images, audio, video, PDFs and plain text directly in the app. No temp files, no downloads.

Keychain-backed

Credentials live in the macOS Keychain. S3 requests are signed by the Rust process — never exposed to the browser runtime.
