Treeview File Navigation

File system style treeview access to your buckets, folders, and files. Just like it should be.

Upload and Download your Files

Drag and drop multiple files, organize your files into folders, download files onto your local machine. Managing your files on S3 just got a lot easier.

Manage File Permissions

No more surprises with some of your files being public on the Internet accidentally. Commandeer shows your file/folder/bucket permissions clearly. Leaning on the safe-side with making ALL new files private by default and allowing you to edit your permissions with a single-click.

View and Test Lambda Connections

View system diagrams showing your buckets connections to Lambda, CloudWatch Alarms, and CloudWatch Logs. Get insights into the infrastructure behind your data by seeing Lambda invocations triggered by S3 file uploads.

Works with LocalStack

No more running complicated terminal commands to see your local S3 files. Commandeer lets you start LocalStack and manage your S3 files. It just works out of the box.
