I built a little tool called Upper that lets you control S3-compatible storage right from the Shortcuts app on iPhone, iPad, and M-series Macs. You can automate things like uploading/downloading files, publishing static sites, or grabbing logs – basically anything you’d usually do in a web UI or terminal.
Credentials are kept safe using the device's Keychain (and sync via iCloud Keychain if you’ve got that on).
I’ve tested it with AWS S3, Cloudflare R2, and Scaleway so far. If you use something else or are missing a specific action, let me know – I'd love to hear what you'd want added.
This is my first time building something with Swift and SwiftUI, so any feedback or suggestions would mean a lot!
