toffeeshare.com
Streams a file from your browser to theirs with no copy in between.
ToffeeShare opens a peer-to-peer WebRTC channel between two browsers, so the file travels from your disk to theirs encrypted in transit and without touching a server — and when both of you are on the same network, without leaving the building. You share a link or a QR code and the transfer begins when they open it. Close the tab and the link is dead, because there was never a copy anywhere else.
Questions
Works the moment the page loads. No account, no email, no trial. The sender's tab has to stay open for the whole transfer, so both people must be at their computers.
No. ToffeeShare does the work inside your browser, so the file never leaves your device — you can load the page, disconnect from the network, and it still works. That makes it a reasonable choice for material containing personal data.
