An open client for the MeshCore LoRa mesh.
MeshCore Open is an unofficial, MIT-licensed Flutter app for MeshCore — the open LoRa mesh radio protocol. Pairs to your node over BLE, USB, or TCP from Android, iOS, Linux, macOS, Windows, or web. No internet, no cell service, no accounts.
Built for the field, not the demo.
The things that get cut from "v1" of most apps are the things you'd actually need at 2am, twenty miles from a cell tower. So they ship in v1 here.
Six platforms, one client
A single Flutter codebase running on Android, iOS, Linux, macOS, Windows, and the web. Pair the same identity from whichever device is in your pocket.
BLE · USB · TCP
Three ways to talk to a node: Bluetooth LE for handhelds, USB serial for desktop rigs, TCP for repeater hubs on your LAN. Pick whatever’s plugged in.
Live mesh map
Plot nodes on OpenStreetMap, trace the actual path messages took, run line-of-sight terrain analysis, share MGRS pins, cache tiles offline before you head out.
Full repeater hub
Manage repeater and room nodes from anywhere on the mesh — status, telemetry, neighbors, full CLI, and a complete settings panel that’s admin/guest-aware.
Modern messaging on a slow radio
DMs, broadcast channels, private communities, reactions, replies, inline GIFs, on-device LLM translation, optional SMAZ compression to squeeze more text per packet.
Open source, no accounts
MIT licensed, built in the open with 14+ contributors and 15 UI languages. No sign-up, no servers, no telemetry — your keys live on the device.
