0xchat

A secure, open-source chat app built on the Nostr protocol.

Available on Android · iOS · macOS · Linux · Windows.

Reliable Hosting

Since Nostr servers are heavily spammed, for reliable media hosting we recommend self-hosting your own media distributor using Originless and adding it as your own server in 0xchat.
