Access your S3 storage directly from the Files app, Finder, and other applications on iPhone, iPad, and Mac. Developed by the creator of Working Copy, this application provides seamless integration with S3-compatible storage services.
Once configured, S3 buckets appear alongside other cloud storage providers, with files available on demand. Files are downloaded as needed and automatically synchronized back to S3 when modified.
The app supports a wide range of S3-compatible services, including AWS S3, BackBlaze B2, CloudFlare R2, DigitalOcean Spaces, MinIO, and others.
Files and directories can be uploaded through the system share sheet on iOS and the Services menu on macOS. The app remembers preferred upload destinations for different file types, streamlining file management.
Pre-signed sharing links can be generated directly from Finder and the Files app, allowing temporary access to files for up to seven days.
Support for server-side encryption with customer-provided keys (SSE-C) and client-side AES-GCM encryption compatible with the Amazon S3 Encryption Client.
Comprehensive support for Shortcuts automation enables operations such as listing, downloading, uploading, and moving files.
The app is free to use with a single server. A Pro Unlock is required for multiple servers, available as a one-time purchase or a monthly subscription, with access shared across iPhone, iPad, and Mac. A one-week free trial allows users to evaluate Pro features before purchase.
I basically gave up on having a mobile client like this since I’ve no time to make it. Just like Anders’ other apps. They’re just so well done, and like someone else said, it was an instant purchase when I saw it.Anders, I don’t know if it matters for your sake, but the account you used for this app is different from ShellFish/Working Copy, I know for me I browse that way a lot (“this app is great, what else do they make”) but you also promote in the apps so it may not hurt.
Fantastic Application with a Great Developer

I don't write reviews but when such an app comes into my life, it needs to be done. This app is everything I need and more to make S3 my new cloud storage at a fraction of the cost of other options. Between deep glacier for archives and instant access in files for more immediate, I am very very pleased! The lifetime purchase and lack of tracking in the privacy label is just a cherry on top! Don't hesitate, get this app today!
Perfect

This app is perfect! The Finder integration makes it an amazing iCloud Drive alternative for large videos. Combined with the low cost of S3 hosting offerings, this has made it easy to store large videos that I can quickly reference on my phone.Thank you for all the care and time you’ve put into this app.
Does what it says, but missing one thing…

Does exactly what it says to, allows me to interact with S3 files right from Finder. The one thing I’d like is a way to copy the URL of a file without all the temporary share query parameters at the end. I have several publicly-readable buckets I use to host things and would love to be able to quickly get links to the files therein without having to delete all the AWS crud at the end.
Upload Files in the in-app browser now allows selecting multiple files at once.
