Features

The s3:// address bar — breadcrumbs when idle, editable key prefix when focused. Type bucket/prefix/ and press Enter to jump there.

Command palette: ⌘K / Ctrl K to jump to a prefix, switch bucket, or run commands.

Keyboard-first interface. Move, open, select, upload, filter and delete without mouse.

Multi-bucket support. Save several connections and switch with one click.

S3-compatible: AWS S3, MinIO, Cloudflare R2, Wasabi, DigitalOcean Spaces, Backblaze B2, Storj, and any S3-compatible endpoint.

File operations: upload with per-file progress, download, delete one or many with stoppable progress.

Zip downloads: selecting multiple objects or a prefix downloads a single archive. No separate download queue.

List and grid views. Grid shows real image thumbnails.

Presigned share links: temporary download URLs, 5 minutes to 7 days.

Drag and drop: drop files anywhere on the window to upload into the current prefix.

Flatten: one keypress lists every key beneath the current prefix, nested folders included. Search a whole subtree instead of walking it.

Sort and filter: by name, size or date. Live filter across every page loaded for the prefix, and across every level when flattened.

Paged listings: prefixes larger than S3's 1,000-entry page load on demand. Sorting and filtering cover every page, drawing stays capped so a 25,000-object prefix doesn't freeze the tab.

Encrypted credential files: save connections to a passphrase-protected .s3vault file and load them on any machine.

Credentials in sessionStorage only. localStorage never touched.

No build step. One file of plain HTML, CSS and JavaScript. Nothing to compile or install.
