Encrypted messaging
Every message is protected with the X3DH double-ratchet protocol so only you and the recipient can read it.
End-to-end encrypted
Messaging that puts SecureMessenger in your control
End-to-end encrypted messaging and calls for people who take their privacy seriously.
Everything you need to communicate securely
Built for people who refuse to compromise between convenience and privacy.
Voice & video calls
Crystal-clear, peer-to-peer WebRTC audio and video calls with encrypted signaling.
Read receipts & reactions
Typing indicators, delivered/read ticks, message reactions, and replies — the little things that make chat feel alive.
Hardened by default
Helmet.js headers, rate limiting, JWT authentication, and hardened input validation out of the box.
Contacts, your way
Connect with people via contact requests, block or unblock anyone instantly, and control who can find you — there's no public directory.
Multi-device
Link web, iOS, and Android to the same account with an end-to-end encrypted device-sync flow — no plaintext ever touches the server.
Engineered for privacy at scale
Security is not a feature here — it is the foundation.
