Xstr
Auto-mirror your X (Twitter) posts to Nostr — free, automatic cross-posting, your key encrypted.
How Xstr works
Mirror your X posts to Nostr automatically, compose to both at once, and cross-post Nostr → X. Four steps:
- Connect your X accountSecurely link X so the app can read your posts — and post back to X if you want.
- Add your Nostr signerUse a browser extension, a remote signer (Nostr Connect), or paste a key. Your key is encrypted and stays in your control.
- Pick your relaysChoose where your Nostr notes get published.
- You're syncedNew X posts auto-mirror to Nostr in the background, with loop protection so nothing bounces back and forth. Compose once to post to both, and see reactions, reposts and zaps on each note.

Connect X, save your Nostr key, add relays, then run a test sync.
