An S3 browser that runs entirely in your browser. No server, no install, no build step — one HTML file, open it and start browsing. Works on desktop and mobile, on any platform.

Features

  • The s3:// address bar — breadcrumbs when idle, an editable key prefix when focused. Type any bucket/prefix/ and press Enter to jump straight there.
  • Command palette — ⌘K / Ctrl K to jump to a prefix, switch bucket, or run any command
  • Keyboard-first — move, open, select, upload, filter and delete without touching the mouse
  • Multi-bucket — 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 progress you can stop
  • Zip downloads — selecting more than one object, or a prefix, downloads a single archive; there is no queue of separate downloads to babysit
  • 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, so you can 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 the listing is flattened
  • Paged listings — prefixes larger than S3's 1,000-entry page load on demand; sorting and filtering cover every page loaded, and drawing stays capped so a 25,000-object prefix does not freeze the tab
  • Encrypted credential files — save your connections to a passphrase-protected .s3vault file and load them on any machine
  • Nothing stored in the browser — credentials live in sessionStorage for the tab; localStorage is never touched
  • No build step — one file of plain HTML, CSS and JavaScript; nothing to compile or install
