Messages that find a way.

A peer-to-peer messenger that keeps working on bad connections, when parts of the network fail, and with no internet at all.

Download See how it works

01 Private by construction

No server. No phone number. No account.

Your identity is a key pair derived from a 12-word recovery phrase. Your data lives only on your devices.

AEncryption

Double Ratchet, post-quantum ready.

End-to-end encryption with a hybrid ML-KEM-768 and X25519 handshake, and Ed25519 identity.

BStorage

An encrypted database on your device.

The SQLCipher key is derived from your recovery phrase. Nothing is kept for you elsewhere.

CTelemetry

Nothing leaves your phone for us.

No analytics, no contact upload and no telemetry. This website sets no cookies and loads nothing from third parties.

02 Works on any network

One message layer. Many ways to deliver it.

Fryva picks the transport that works right now, and falls back when a path fails.

AISelf-healing

A connection that heals itself.

When part of the network breaks, Fryva notices, works out which layer failed, from DNS through TCP and TLS to HTTP, and switches to a transport that still works. The model that picks the route learns on your device, with federated learning.

✓Honest status

Delivery you can trust.

Delivery indicators reflect the real state of the transport, not an optimistic guess.

03 Offline

Even with no internet.

Nearby devices talk directly over local Wi-Fi and Bluetooth. Messages for offline peers wait in store-and-forward mailboxes.
