DropLink — Local File Sharing

DropLink is a cross-platform file sharing app that lets you send files of any size between Mac, Windows, iPhone and any web browser — without the cloud, without accounts, and without giving up your privacy. It's the AirDrop alternative that finally works with every device on your network — and the WeTransfer alternative with no size limits.

HOW IT WORKS

On the same WiFi, DropLink discovers nearby devices automatically (Bonjour/mDNS) and transfers files peer-to-peer over QUIC, the protocol behind HTTP/3. No server in the middle, no cloud upload: bytes go straight from one device to the other at full LAN speed.

Across different networks, DropLink switches to direct Internet P2P with NAT traversal (hole punching). Files travel end-to-end encrypted, never stored on a third-party server. If a direct path isn't possible, an encrypted relay forwards traffic it cannot read.

PRIVACY BY DESIGN

End-to-end encryption on every transfer (TLS 1.3 on LAN, curve25519 + TLS 1.3 on Internet P2P) Zero cloud storage — files never sit on anyone's server No expiring links, no terms of service covering your content No account, no email, no tracking, no telemetry Optional password protection on every share Works fully offline on local networks The receiver doesn't need the app — a browser is enough CROSS-PLATFORM, REALLY

Native macOS app (SwiftUI) with Finder share extension Native Windows app (Tauri v2) with system tray and autostart Native iOS app with Share Sheet and Live Activity progress on the lock screen Web UI embedded in the app — send to any device with a browser BUILT FOR SPEED

BBR congestion control, 0-RTT resumption, hardware-accelerated ciphers, MTU discovery, parallel downloads. DropLink saturates whatever network you give it — 50+ MB/s on modern WiFi, 100+ MB/s on gigabit Ethernet: the bottleneck is your network, not the app.

SMART FEATURES

No size limits: transfers are streamed, so a multi-hundred-GB folder is the same drag & drop as a PDF Automatic device discovery; drag & drop files and folders (auto-zipped) Resumable downloads; receiver accepts or rejects before the transfer starts Real-time progress, speed, ETA and transport type (LAN / P2P / Relay) QR code pairing for quick browser-to-app sharing AP isolation detection (warns when hotel WiFi blocks device-to-device traffic) UI in 9 languages WHO IT'S FOR

Photographers delivering full-resolution RAW shoots to clients, video teams moving 4K footage between set and edit bay, designers moving assets between Mac and Windows, developers pushing builds to an iPhone, families sharing photos without Google Drive or iCloud, and teams that can't (or won't) use public cloud for file transfer.
