Dragy

Moving a file from a phone to a laptop should not need a cable, an email to yourself or a cloud account. We built Dragy to make it one gesture, on every platform, without giving up privacy.

Overview

Dragy is a product designed and built by Nexlla at dragy.nexlla.com, with apps for Android, iPhone and iPad, Windows, macOS and Linux, and a web app that runs in any browser.

What We Designed and Built

• On the same network, files go straight from device to device and never leave the network. Anywhere else, they travel peer to peer, or through a relay that only forwards encrypted data and stores nothing.
• Nearby devices find each other automatically; others connect with a short code or a QR code. A free account adds all of a user’s devices to one view, and files for offline devices wait, encrypted, until they come online.
• A Dragy folder on the desktop: drop files into “Send to” and they are sent; received files land in their own folder.
• Encrypted share links whose key never reaches the server, with expiry and download limits.

Approach

One small protocol core, with no dependencies, runs in browsers, desktop and mobile alike, so every platform behaves the same way. The interface is built around a single “orbit” of devices: pick one or several and drop.

Outcome and Impact

Dragy is live at dragy.nexlla.com. It shows how we build cross-platform products from one codebase, with security designed in from the start.
