Overview

Hiras turns an Android phone into a self-hosted, LAN-only SMS gateway. Anything on your network can send and receive SMS through the phone's SIM over a small REST API, with no accounts, no cloud, and no subscriptions.

These pages cover setup, the full API, the built-in test modes, inbound webhooks, and how Hiras handles your data. Every detail here reflects what the app actually does.
