I like it because there isn't any third party or service for me to trust, but I can still have unique complex passwords for each purpose. It feels pretty much the same as having them all in my head.
It just posts an encrypted json blob to a CGI script that waits for another connection with the same ID. The script then connects those two connections so that anything one sends the other receives using a FIFO, so no disk involved and they can stream as much as they want to each other.
Poorly at present, but it runs as a website on anything with a recent browser: https://kybernetikos.github.io/sinkless/ and you can copy and paste, or there is a node script that will generate the same passwords.
I'd like to make the UI work better in general, but in particular on mobile devices. But then I have many projects I'd like to make time for, and this one is probably usable enough for me for now.
