Safe, simple, and private messaging for the people who matter
XChat is a privacy-first communication system organized around independent circles. Switch between friends, family, and work in one tap—each circle stays separate and undisturbed. Built on Nostr, no phone number or email needed; your identity is your keys, and you decide where your data lives. You keep full control over your data without sacrificing simplicity or usability. Made for small, trusted circles where privacy and clear boundaries matter.
