Comms that hold
when the coast does not.
Gulf Coast Mesh is a volunteer-built communications fabric — anchored in Louisiana, growing across the US Gulf Coast. Open hardware. Decentralized routing. Real neighbors on the other end.

Rooftops, towers, and front porches — all on the same mesh.
Mesh radios pass messages neighbor-to-neighbor over license-free LoRa. Backbone repeaters live on real towers and high rooftops, with three more tower sites coming online in the next three months.
Live maps you can actually read
Watch Meshcore and Meshtastic activity ripple across the coast in real time. See who heard whom, which repeaters are hot, and where the next install would matter most.
Built for hurricane season
When the cell network drops and the internet goes with it, the mesh keeps moving — on solar, battery, or a USB pack — backed by our repeaters on tall sites.
Open and tinkerable
Open firmware, open docs, open neighbors. Hack the stack, file a PR, or just show up and ask questions.

Meshcore
One obsession: messages that arrive. Meshcore is the backbone of the Gulf Coast network — reliability-first routing built to scale from a single rooftop to the whole coast.
Meshcore
Reliability-first routing with deep pathing — up to 32 hops for coast-scale links and repeater backbones.
From box-fresh radio to the coast-wide net in three steps.
