Kora
Mesh Messaging for Your Neighborhood
Chat with neighbors using Bluetooth and Wi-Fi Direct — no cell towers, no internet, no servers. Kora creates a local mesh network so your building stays connected even when the grid goes down.
How Kora Works
A mesh network in your pocket — no servers, no internet, no monthly fees.
Mesh Networking
Kora uses Bluetooth Low Energy and Wi-Fi Direct to form a local mesh network between nearby devices. Messages hop from phone to phone.
No Internet Required
Send messages, share posts, and chat in groups without any cell service or Wi-Fi. Perfect for buildings, campgrounds, and emergencies.
Community Board
A shared bulletin board for your building or neighborhood. Post lost & found, events, safety alerts, and for-sale items — all local.
Emergency Broadcast
Send priority emergency messages that relay through the entire mesh network with maximum reach — even through offline devices.
Building Networks
Create a dedicated group for your building with a QR code poster. Neighbors scan to join and instantly connect to the local mesh.
Privacy First
No accounts, no phone numbers, no cloud. All communication stays on-device and within the local mesh. Pseudonymous by default.
Get Connected
Three steps to a mesh-connected building.
Install Kora
Download from Google Play. No sign-up, no phone number — just open and go.
Start the Mesh
Tap "Start Mesh" and Kora begins discovering neighbors via Bluetooth and Wi-Fi Direct.
Invite Neighbors
