## What it is
A Dockerized REST API wrapper around signal-cli that exposes Signal Messenger functionality (registering numbers, sending/receiving messages, group management, attachments, device linking) over HTTP. It is written in Go and offers multiple execution modes trading off latency and memory usage.

## Use cases
- send signal messages from a script via http
- integrate signal notifications into home automation
- build a signal chatbot that receives and replies to messages
- send alerts to a signal group from monitoring systems
- automate signal messaging without the desktop app
- link signal-cli as a secondary device and control it via api

## When to choose
- you want to automate Signal messaging through a simple HTTP API
- you prefer a self-hosted Docker container with minimal setup
- you need to send/receive Signal messages from any language that can make HTTP calls

## When to avoid
- you need an official or fully supported Signal API with guarantees against account bans
- you cannot run Docker or a persistent container
- you need high-throughput messaging beyond what a single signal-cli instance can handle

## Facets
- artifact type: service
- maturity: active
- function: http-server, api-framework
- domain: messaging-platforms, self-hosted
- platform: self-hosted, go
- tags: signal-messenger, rest-api, signal-cli, messaging, dockerized, automation, docker, linux
