The original
PairDrop
Browser-based device-to-device file transfer with no install or signup.
Replacements
Listings that take over the same core job as PairDrop.
croc
Sends a file between any two computers with one command and a short code phrase, end-to-end encrypted.
croc uses a command line tool or browser version with a code phrase and end-to-end PAKE encryption, and resumes interrupted transfers, but both ends need croc.
OnionShare
Shares files, hosts sites and chats anonymously over Tor.
OnionShare is a desktop app that shares files anonymously over Tor with no third-party server, but both sides need Tor and transfers are slow.
Send
Self-hostable encrypted file sharing, continuing Firefox Send.
Send shares browser-encrypted links that expire by time or download count, so the devices do not need to be online at the same time.
Smash
A web service and mobile app for sending large files of any size as a download link.
Smash is a closed-source freemium service storing files on its servers until downloaded, with iOS and Android apps and password protection.
Also worth comparing
These listings name PairDrop as their own alternative, so the relationship runs both ways.
ffsend
A command-line client for sharing encrypted files through Send-compatible servers.
PairDrop moves files between devices in the browser with no install or account, but both devices must have the page open at the same time.
MASV
A hosted service for transferring very large files and media, used from the browser.
PairDrop is free and open source, sending files device to device in the browser, but both devices must be online with the page open at once.
