Nostr Signer (formerly Nostr Connect) от Ren Amamiya

Nostr Signer allows you to securely sign nostr events without sharing your private keys with clients.

Key features:
- Implements NIP-07 standard for seamless client integration
- Supports NIP-04 and NIP-44 encryption
- Fine-grained permission control per client
- Clean, modern interface
- Your private keys never leave your browser

With Nostr Signer, web clients can request signatures through a standardized interface while you maintain full control over your keys. Approve or deny each request individually, and manage your permissions from the settings page.
