Nostra.chat

Nostra.chat is a 100% client-side Progressive Web App for decentralized messaging, forked from Telegram Web K. It replaces the Telegram backend with peer-to-peer encrypted chat over Nostr relays and integrates Tor via WASM for network-level privacy. No servers, no accounts, no install — just cryptographic keys and a browser.
