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
i have used the filepizza but it was not optimized well so i decided to built my own
Airlynk — browser peer-to-peer file sharing without servers
I built Airlynk because I was frustrated with every peer-to-peer file sharing tool I tried — connections would fail, transfers would stall, and NATs or firewalls always got in the way. Nothing I tested was reliable enough for real use, and I wanted a solution that actually worked.
So I decided to build it myself. Over several months, I crafted Airlynk to work entirely in the browser, using WebRTC for direct peer-to-peer transfers. I designed it to be simple, fast, and server-free, with fallback relays only when absolutely necessary. Chunked transfers and progress tracking make even large files move smoothly.
The journey taught me a lot about peer-to-peer networking, browser limitations, and user experience. My goal with Airlynk is to make file sharing effortless for everyone, and I’m excited to keep improving reliability and security based on real feedback from users.
