How it works

Direct to your storage, from the first click.

1

Add to Chrome

From the Chrome Web Store. A welcome page walks you through your first connection.

2

Add a connection

Chrome asks you to allow that storage host, and only that host. Keys are saved in your browser profile.

3

Work

Browse, edit, move, search and share, all directly against S3. Nothing passes through Stream Vessel.

First-run welcome page: your credentials stay on this device, set up your first S3 connection
New connection dialog with provider tiles for AWS, Cloudflare R2, Backblaze B2, MinIO, Wasabi, DigitalOcean Spaces and Other
Why the extension

Private by construction.

There is no Stream Vessel server in the path. What you see in the network tab is your browser talking to your provider.

  • No account. Nothing to sign up for.
  • Keys stay in your browser profile. Never sent to us.
  • No CORS rules to add. The extension talks to S3 directly.
  • Minimal permissions. storage, alarms, identity. Host access is optional and asked per connection, with recovery if a grant is revoked.
  • Import and export connections as JSON. Move them between machines in seconds.
  • One-click issue report. When a connection keeps failing, send a redacted report with a preview of exactly what leaves your machine.
Everything the Cloud explorer does

Same explorer. Same editor. Same transfers.

Several panes side by side, drag between connections, cut, copy and paste, bucket search with a cost-aware pause, previews, the code editor, presigned links, Google Drive import and send. Scoped connections and Assume Role are here too.
