What is MurMur Chat?

MurMur is a free, open-source (AGPL-3.0) web messenger focused on privacy and simplicity.

Key features:

End-to-end encryption (ed25519/x25519 + AES-GCM) — keys live in the browser, the relay server cannot read messages
No phone number or personal data required — your identity is a cryptographic key pair
Progressive Web App: installable on iOS, Android and desktop without an app store
Self-hostable relay (single Rust binary) — deploy your own server in minutes
Ephemeral by design: the relay stores encrypted messages only until delivery (TTL), no message history on the server
Web push notifications, voice/video calls, photo sharing
Multi-language interface

Alternative to Telegram, Signal, WhatsApp and Session for users who want private messaging without installing anything or handing over a phone number.
