ShareDrop (and its cousin Snapdrop) brought AirDrop-style sharing to the browser: devices on the same Wi-Fi network see each other and can beam files across. It's great in the same room. But the moment your recipient is on a different network — a friend in another city, a client across the world — local-discovery tools hit their wall.
Where local P2P tools stop
ShareDrop discovers peers on your local network. To share with someone remote you have to open a specific room URL on both ends, and transfers across networks depend heavily on how well the connection negotiates. There's also no password protection and no way to customize your link.
ZetaShare: the same directness, without the distance limit
ZetaShare is built for internet-wide P2P from the ground up. You drop a file, get a link, and send it to anyone anywhere. Their browser connects directly to yours over WebRTC with DTLS 1.3 encryption, and the file streams across:
- Works across any network — same room or different continent.
- No size limit — the file never touches a server, so nothing caps it.
- Password protection — lock a transfer so only your intended recipient can start it.
- Custom links — create a link that's easy to read out loud or type.
- No accounts, no installs — both sides just use a modern browser.

Which one should you use?
If everything you share stays within one room and one Wi-Fi network, ShareDrop remains a neat tool. The moment your files need to travel further — client deliveries, family videos, project files to a remote teammate — you need P2P that works across the open internet.
Send a file with ZetaShare and see how simple cross-network P2P can be.
