Some other WebRTC file transfer options:

* https://wormhole.app/ (my recent fave, by creator of WebTorrent, holds for 24h, https://instant.io by same)

* https://file.pizza/ (p2p, nothing stored)

* https://webwormhole.io/ (same, but has a cli)

* https://www.sharedrop.io/ (same, does qr codes)

* https://justbeamit.com/ (same, expires in 10 minutes)

* https://send.vis.ee (hosted version of this code)

* https://send.tresorit.com/ (not p2p, 5 GB limit, encrypted)
