AirDrop? kinda Apple-only. Cloud drives? Size limits? Waiting for uploads? WeTransfer? caps caps caps. Browser uploads? No folders supported? One network hiccup and you start over.

What Zynk does: Transfers files between any devices/OS on your local network, also without Internet connectivity, between you and anyone else over the Internet.

- Efficiently transfer files or folders of any size, rsync-style, terabytes welcome.

- Resumable: close your laptop, lose WiFi, switch networks, pick up where you left off

- All platforms supported: Mac, Windows, Linux, iOS, Android, Android TV, Steam Deck for everyday use, CLI for power users and automation,

- Web share and drop links for sharing or receiving transfers from anyone with the browser

- Media viewer/player built into the app

- Messaging + reactions for efficient collaboration

- P2P + Always End-to-end encrypted (we can't see your files or messages)

I wanted something that "just worked" the way AirDrop does, but across everything I own and the people I care about. Built-in chat because context can matter when you're bouncing stuff between people. File preview/play built in. Passes the mom test.

It's being developed to be a one stop shop tool that is capable of covering any file transfer need and scenario easily, efficiently, and securely/privately.

Free, ad free, with Pro tier available for those who need a lot more. Would love feedback from the HN crowd!

We have a long roadmap ahead. Expect new and unique feature announcements soon.

Happy to answer any questions.
