Bunker46 од Djuri

Bunker46 Extension lets you use Nostr-enabled websites without storing your private keys in the browser. Your keys stay on your own Nostr signer (such as Bunker46 or any NIP-46 server); the extension only forwards signing requests when you approve them.

What it does:
• NIP-07 provider — Exposes window.nostr (getPublicKey, signEvent, getRelays, nip04/nip44) so Nostr apps can request signatures without holding keys locally.
• Remote signer — You connect once with a bunker URI from your signer; the extension keeps a session and proxies allowed requests to it.
• Per-domain permissions — Each site must be allowed (once or always) before it can use your Nostr identity. You can revoke domains or individual methods from the extension popup.
• nostrconnect links — Clicking nostrconnect links opens your configured Bunker46 instance so you can add or manage connections there.

Privacy & security: Private keys never leave your signer. The extension only stores your session and per-site permission choices locally. It does not collect or transmit personal data.

Requires a Nostr signer that supports NIP-46 (e.g. Bunker46). Open source: https://github.com/dsbaars/bunker46-extension
