Private messaging and voice & video calls, encrypted end to end. No phone number, no ad tech, and no one in the room you didn't invite.
Windows 10 & 11 · 64-bit · portable ZIP · or run it in your browser
Messages and calls are encrypted on your device and decrypted only on your contact's. The relay carries ciphertext it can never read.
Low-latency 1:1 calls, with the media stream encrypted end-to-end via SFrame — the server routes packets it can't decode.
No open sign-ups. Accounts are created with codes, so only the people you invite can ever get in.
