Space

space. sends photos, videos, documents, links and plain text between your devices, and the whole transfer comes down to one six-character code. The person on the other side installs nothing: they open the web app, type the code and the transfer starts.

The payload is sealed on your device before it leaves, using a key derived from that code, and the relay only stores sealed bytes. A drop is removed after about 15 minutes, so it is a hand-off rather than a storage locker. Nearby transfers need no account at all.
