S3 vs Loopback

S3 Browser is a powerful and intuitive iOS application designed for managing Amazon S3 and S3-compatible object storage services. Whether you're a developer, system administrator, or business user, S3 Browser provides a seamless experience for accessing and managing your cloud storage directly from your iPhone or iPad.

Loopback opens the web services on your private network, right on your iPhone. Your NAS dashboard, the admin panel on your server, the dev build on your laptop: these pages only open on your own network. Loopback connects to them from your phone and shows them in a built-in browser. No system VPN, and nothing exposed to the internet. Two ways to connect, picked per device • Tailscale Direct: sign in to Tailscale in the app and your tailnet devices are listed for you. Bookmarks open device:port directly with no account or key, and every port on the device is reachable. Loopback joins the tailnet on its own, so your phone's system VPN stays off. • SSH Tunnel: for machines without Tailscale, enter the address, username, and a password or private key (Ed25519 / RSA). Loopback sets up a local port forward and opens the page. Services that only listen on localhost work too. Bookmark cards, one tap away • Save each service as a color card with its own icon and path • Forward several ports from one card, for apps with a separate frontend and backend • Filter by device with the tabs at the top, or type an address like nas:8080 to open it right away • Ports are checked before connecting, and connections close when the app goes to the background or times out Private by design • Passwords and private keys stay in your device Keychain • No backend and no data collection • Export and import your setup to move to a new phone Loopback: your private network, one tap away.
