i2o

Send files to anyone.
They open on the other Mac as a drive.

Send

Files stay on this Mac and stream straight to the other one. Keep this tab open until they're done.

Receive

You need the free i2o receiver on this Mac. Download it, then come back here.

How it works

  1. 1

    The sender drops files in this page and gets a six‑character code. Nothing uploads anywhere.

  2. 2

    The receiver enters the code. The two browsers connect directly to each other.

  3. 3

    On the receiver's Mac the files appear as a drive right away. Bytes stream from the sender only when something is opened, so a 200 GB folder is usable in seconds.

Works in Chrome, Edge, Firefox and Arc on both sides. The receiver is a Mac for now. If a direct connection can't be made, the transfer is relayed and will be slower.
