MeshTrax

MeshTrax is a free, open-source companion app for MeshCore LoRa mesh networking devices. Connect to your radio and send messages across the mesh — no internet, no accounts, and no cloud servers.

Communicate off-grid over long-range LoRa radio — hiking, at an event, in an emergency, or just exploring mesh networking. Your messages, contacts, and keys stay on your device and your own hardware.

Note: MeshTrax is an independent, community-built client and is not the official MeshCore app. It requires a compatible MeshCore device to be useful , it is not a standalone messenger.

Optional online features (maps, terrain, GIFs) connect to third-party services only when you use them. See the privacy policy for details.
