i personally prefer file.pizza, especially considering it is an open source webrtc implementation that doesn't persist the data via any middle man (https://github.com/kern/filepizza)
Thanks for sharing that, it is also very cool! I think the two projects have slightly different use cases though. Two things come to mind:
* Sender and Receiver must directly connect using file.pizza, revealing IP addresses to one another.
* Both users must be online at the same time with file.pizza, and be able to communicate in near real time to exchange the link.
