No internet? Still talking.

Most days, Ratspeak runs over the internet, like any app. Now take things away.

  1. No internet.

    Same Wi-Fi. Devices on one Wi-Fi or LAN still find each other.

  2. No Wi-Fi.

    Bluetooth. Phones in the same room talk directly.

  3. Not in the same room.

    LoRa radio. Long range with no towers or internet. Needs a LoRa radio or one of the handhelds above.

  4. No central server.

    Devices relay for each other. One message can hop across all of the above.

  5. See what a relay sees

No sign-up.

Ratspeak makes your address on your device. People reach you with it, and it says nothing about who you are.

Your address

Made on your device

So how do people find you?

  • Join a public network. Pick a public server in the app. People there show up under Peers, and every message stays end-to-end encrypted.
  • Add friends. Scan their contact card QR in person, or paste the address they send you.
  • Meet people nearby. Turn on Local network or Bluetooth and people close by show up too, no internet needed.
