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
Only somewhat related, but is there an easy tool for sending files from one device to another when on the same network? I imagine that scenario shouldn’t need some third party server to connect to but I’ve yet to find a tool like this.
Much simpler and more direct than the other suggestions: LocalSend.
Also fully open source, local only, cross platform. Only works in the same network, obviously. That’s the point.
