Peer-to-peer file transfers in your browser Cooked up by Alex Kern & Neeraj Baid while eating Sliver @ UC Berkeley.
Using WebRTC, FilePizza eliminates the initial upload step required by other web-based file sharing services. When senders initialize a transfer, they receive a “tempalink” they can distribute to recipients. Upon visiting this link, recipients’ browsers connect directly to the sender’s browser and may begin downloading the selected file. Because data is never stored in an intermediary server, the transfer is fast, private, and secure. (Your PC must be online while the recipient download the file(s), if you shutdown the PC or goes offline, the download also stops)
You can selfhost it or use the official instance
To be fair, this one’s been around for a while and I believe it’s actually p2p, iirc. Wormhole stores your files on their servers for a little bit if they’re < 5 Gb.
Waaait what wormholes are we talking about? I am aware these three, sounding similar but incompatible with another:
wormhole.app is the only one I’m familiar with. Both it and the file pizza in the OP were built off of webtorrent architecture.
