We think it's encouraging that other products that offer end-to-end encryption like Signal and WhatsApp have managed to handle abuse, malware, and other threats.
but file.pizza doesn't seem to work anymore (for me at least)
wormhole.app is comparable to the now defunct uplovd.com and Firefox Send.
We're considering a "P2P only" option that doesn't send anything to the cloud. Since files are end-to-end encrypted, it doesn't matter from a privacy perspective, but it does help to save bandwidth (and cost for us) if you know you don't need the files stored.
But I have to agree with the commenter above, the background made me feel really dizzy and strange in a way I've never experienced from a computer screen before.
