Off the grid.
Never out of reach.
Your message. Nobody else's business.
Reliable off-grid messaging for the places ordinary networks don't reach. From the deep backcountry to critical disaster zones, Rhun ensures your message gets through without relying on traditional infrastructure.
Communication without infrastructure.
Most communication tools assume stable infrastructure. Rhun is built for places where coverage is weak, absent, contested, or too risky to depend on.
Serverless mesh networking
Devices form a peer-to-peer mesh automatically. Your messages route through whoever is nearby. There is no central node and no single point of failure. As people move, the network moves with them.
End-to-end encrypted
Every message is encrypted on the sending device and decrypted only on the recipient's. Nothing readable in transit. Not by us, not by anyone passing the message along.
Connect your LoRa radio, extend your reach
If you have a LoRa (long-range) radio, plug it in and Rhun will use it to push messages further: across valleys, through forests, or over open water. Several kilometres further per radio hop.
Offline-first by design
No dependence on central account infrastructure. Devices pair directly, messages move across the mesh, and delayed delivery handles the moments when recipients are temporarily out of range.
If a signal can go there, Rhun can go there.
Mining and underground ops
Deep enough that cell coverage disappears. Rhun keeps crews connected with each other and with the surface team.
Offshore and maritime
On vessels or rigs where satellite uplink is limited or expensive. Rhun keeps the crew connected without relying on external infrastructure.
Forest and remote field ops
Survey teams, environmental researchers, emergency responders, and anyone working in terrain where coverage isn't a given.
Infrastructure-denied environments
When the communications infrastructure around you is unavailable, contested, or compromised. Rhun doesn't depend on it.
