## What it is
WatchYourLAN is a lightweight network IP scanner written in Go with a web GUI, designed to discover and track hosts on a local network via ARP scanning. It sends notifications when new hosts appear, maintains online/offline history, and can export data to InfluxDB2 or Prometheus for Grafana dashboards.

## Use cases
- monitor which devices are connected to my home network
- get notified when a new device joins my LAN
- track online/offline history of network hosts
- detect unknown devices on my network for security
- visualize network host data in a Grafana dashboard
- keep an inventory of all devices on my LAN

## When to choose
- you want a simple, lightweight self-hosted LAN device scanner with a web UI
- you need alerts when new devices appear on your network
- you want to export network presence data to Prometheus/InfluxDB and Grafana
- you run a home lab or small network and want device history

## When to avoid
- you need built-in authentication (requires external SSO like Authelia)
- you need deep packet inspection or full network monitoring like Nagios/Zabbix
- you need to scan networks across multiple subnets or WANs
- you need enterprise-grade intrusion detection with signature analysis
