Start
Pick a name once and it's remembered. You get a session with a 6-digit code that lasts 10 minutes.
Clipboard, shared between 2–4 computers
Copy on one.
Paste on the other.
Link your laptop, your desktop, or a friend's machine with a 6-digit code. What you copy on one shows up on the others. It goes straight from browser to browser.
You get a code and an invite link.
- Peer-to-peer
- Encrypted
- No uploads
- No sign-up
Link up
Read the code out, or send the invite link, which skips the code. Up to 4 people per session.
Copy, paste, send
Copy something and come back to the tab, or press CtrlV on the page. It lands on everyone else's clipboard. Drop a file and it goes to them too.
Private by design
Nothing sits in the middle.
Tether links your browsers to each other, not to a cloud. Files and clips travel over a direct, encrypted connection, so there's no upload, no copy left on a server, and nothing for anyone to leak later.
Serverless transfer
Files go straight from your browser to theirs over WebRTC. They're never uploaded, so there's nothing stored to delete.
Encrypted on the wire
Every link is encrypted with DTLS, the same standard behind video calls in your browser. Keys are made fresh for each connection.
No accounts
No email, no password, no profile. Your name lives in a cookie on your own device, and nowhere else.
Short-lived by default
Join codes expire after 10 minutes, rooms hold 4 people at most, and idle sessions vanish after 12 hours.
What a browser can and can't do
No install, so a few rules apply.
- Syncing happens when you switch to the tab. Browsers only let a page read your clipboard while it's in front, so switch to Tether after copying and it sends. In Firefox and Safari, press CtrlV on the page.
- Incoming clips land when you switch to the tab. Everything received also stays in the list, one click to copy.
- You set your own status. A website can't see which app you're using, so you pick it: VS Code, Figma, whatever.
- Files never touch a server. They need a direct link. Text clips use one too, and only fall back to a relay if a direct link can't be made, where they're deleted after two minutes.
