Local-first · off-grid · open source

Messaging that grows where you are.

LOAM is a messaging network with no internet, no accounts, and no cloud. One person hosts it on a laptop, a Raspberry Pi, or a phone. Everyone nearby scans a QR code and joins over local WiFi.

Runs offline. Anonymous by default. AGPL-licensed.

How it works

Three steps to a network of your own

  1. 1

    Someone hosts

    Run LOAM on a laptop, a Raspberry Pi, or an Android phone. It starts a local WiFi hotspot and prints a join QR — no servers, no setup.

  2. 2

    People scan & join

    Nearby devices scan the QR to connect and open LOAM in the browser. Everyone gets an anonymous, ephemeral identity — no email, no phone number.

  3. 3

    You talk, locally

    Post to channels, reply in threads, DM, react — and optionally chat with a local AI assistant. Everything stays on the local network.

What you get

Small, private, and resilient

Local-first

Messages live on the local network and in your browser's cache. No cloud round-trips, works with zero internet.

Anonymous & ephemeral

A generated name and avatar, no account. Optional disappearing-message timers keep history minimal.

Channels, threads & DMs

Public channels for coordination, threaded replies for focus, and private direct messages between two people.

Installable PWA

Add it to your home screen and keep reading against the local cache even when the signal drops.

Optional local AI

Point it at a local Ollama model and an assistant appears as a contact — answers stay on the host, offline.

Phone as the host

The Android app turns a phone into the node: it runs the server, starts the hotspot, and shows the join QR.

Who it's for

For people, where the network isn't.

LOAM is built for moments the internet can't reach — and for keeping ordinary people connected when staying in touch is what matters most.

  • Communities off the grid — remote areas, boats, camps, anywhere without coverage.
  • Events & gatherings — a room, a venue, a field: a private space to coordinate.
  • When infrastructure fails — outages and disasters, where a hotspot is the only link.
  • Organisers & helpers — a simple, no-account way to reach the people around you.

These protections exist to keep everyday people safe and connected — not to hide wrongdoing.

Open source

Yours to run, read, and improve.

LOAM is free and open source under the AGPL. Read every line, run your own node, and help build the roadmap — from encrypted storage to LoRa relays that reach beyond one hotspot.

  • Preact PWA client
  • SQLite storage, encrypted at rest
  • Deterministic anonymous identities
