What's different from wetransfer?
WeTorrent is a commercial solution, http based. The Send.Firefox is also http based, but with a simpler interface / ux.
Instant.io is a bittorrent type of file transfer - serverless transfer - P2P and secure, no limits, direct browser to browser via the WebRTC tech
Do counter my explanation if I'm off 
Send Firefox is really dead simple.
Hmm, very interesting.
I wonder if Send will manage to persist if it gets popular. The running costs could mount up significantly.
Also good to see someone did something a bit more durable than the initial tests with Bittorrent-over-WebRTC!
I have no idea why WebRTC based tech is not mainstream - found some cool use cases for it but still underground
WebRTC's used pretty extensively for chat applications - Discord's probably the best known example.
But for file transfers it doesn't seem to have taken off. Not sure why.
