Hi Product Hunt, I'm Marco, an indie dev from Italy. DropLink exists because of my own desk: a Mac, a Windows PC and an iPhone, all a meter apart, and the standard way to move a big file between them was to upload it to someone's server and download it back. I did that for years without questioning it. Then WeTransfer had its AI-training terms episode last year, and being annoyed suddenly felt justified. Why does a file going one meter need a middleman at all? So DropLink skips the middleman. Devices on the same network find each other over mDNS and transfer peer-to-peer over QUIC. On normal Wi-Fi I see 50+ MB/s, more on Ethernet. Across the internet, app-to-app transfers go direct P2P with NAT traversal, and when a corporate firewall kills the direct path, an encrypted relay forwards packets it can't read. Browser links work differently: those downloads always stream through our relay, encrypted in transit and never stored. Nothing sits on a server either way, and there's no size cap: a 300 GB folder of video dailies is the same drag and drop as a PDF. The person receiving doesn't need the app or an account, they just open a link in the browser. Under the hood it's a Rust core. TLS 1.3 with TOFU fingerprints on the local network, Noise protocol for remote transfers, BLAKE3 checking every chunk as it streams. Native apps for macOS, Windows and iOS. Android is in testing (happy to add beta testers, ask below). All of it free. Two limitations you'd find anyway, so I'll say them first: your machine has to stay online while a transfer runs, that's the price of there being no cloud copy. And remote speed is whatever the slower of the two connections allows. I'd love brutal feedback, especially from photographers and video editors who ship big files for a living. What would make you switch?
