How it works

Three steps, then it runs itself.

  1. 1 Connect your X

    Secure OAuth — your password is never shared.

  2. 2 Add your Nostr key & relays

    Encrypted before it's stored. You stay in control.

  3. 3 Posts auto-mirror

    New X posts — text and images — appear on Nostr automatically.

Do not share exported backups. They may contain encrypted account data.

Relay Health

Primary relays are tried first. Backup relays fill in when needed.
