Private Messaging.
No Servers. No Internet.
Txter is a mesh messaging app that sends end-to-end encrypted messages over BLE, Wi-Fi Direct, and LoRa — no cell towers or internet connection required.
Built Different
Designed from day one to work without infrastructure.
End-to-End Encrypted
Every message is encrypted with Ed25519 keys before it leaves your device. Only the intended recipient can read it.
Multi-Hop Mesh Relay
Messages hop across nearby devices to reach their destination. Your phone is both a messenger and a relay node.
No Account Required
Your identity is a cryptographic key pair generated on your device. No phone number, no email, no sign-up.
BLE + Wi-Fi Direct + LoRa
Three transport layers for maximum reach. Bluetooth for close range, Wi-Fi Direct for higher throughput, LoRa for kilometers.
Privacy Verified
No servers, no accounts, no data collection. Our privacy claims are self-evident — everything stays on your device.
Censorship Resistant
No central server to block or shut down. The mesh is the network — as long as devices are nearby, messages flow.
How It Works
Install & Generate Identity
Download Txter and a unique Ed25519 key pair is generated locally on your device — that's your identity.
Exchange QR Codes
Meet your contact in person and scan each other's QR code. This creates a trusted, verified connection.
Send Messages Off-Grid
Messages are encrypted and relayed across the mesh. No internet, no towers, no third parties.
