# NetAlertX - Network, presence scanner and alert framework
Get visibility of what's going on on your WIFI/LAN network and enable presence detection of important devices. Schedule scans for devices, port changes and get alerts if unknown devices or changes are found. Write your own [Plugin](https://github.com/jokob-sk/NetAlertX/tree/main/docs/PLUGINS.md#readme) with auto-generated UI and in-build notification system. Build out and easily maintain your network source of truth (NSoT).

## π¦ Features
### Scanners
The app scans your network for **New devices**, **New connections** (re-connections), **Disconnections**, **"Always Connected" devices down**, Devices **IP changes** and **Internet IP address changes**. Discovery & scan methods include: **arp-scan**, **Pi-hole - DB import**, **Pi-hole - DHCP leases import**, **Generic DHCP leases import**, **UNIFI controller import**, **SNMP-enabled router import**. Check the [Plugins](https://github.com/jokob-sk/NetAlertX/tree/main/docs/PLUGINS.md#readme) docs for a full list of avaliable plugins.
### Notification gateways
Send notifications to more than 80+ services, including Telegram via [Apprise](https://hub.docker.com/r/caronc/apprise), or use native [Pushsafer](https://www.pushsafer.com/), [Pushover](https://www.pushover.net/), or [NTFY](https://ntfy.sh/) publishers.
### Integrations and Plugins
Feed your data and device changes into [Home Assistant](https://github.com/jokob-sk/NetAlertX/blob/main/docs/HOME_ASSISTANT.md), read [API endpoints](https://github.com/jokob-sk/NetAlertX/blob/main/docs/API.md), or use [Webhooks](https://github.com/jokob-sk/NetAlertX/blob/main/docs/WEBHOOK_N8N.md) to setup custom automation flows. You can also
build your own scanners with the [Plugin system](https://github.com/jokob-sk/NetAlertX/tree/main/docs/PLUGINS.md#readme) in as little as [15 minutes](https://www.youtube.com/watch?v=cdbxlwiWhv8).
### Workflows
The [workflows module](https://github.com/jokob-sk/NetAlertX/blob/main/docs/WORKFLOWS.md) allows to automate repetitive tasks, making network management more efficient. Whether you need to assign newly discovered devices to a specific Network Node, auto-group devices from a given vendor, unarchive a device if detected online, or automatically delete devices, this module provides the flexibility to tailor the automations to your needs.

## π Security & Privacy
NetAlertX scans your local network and can store metadata about connected devices. By default, all data is stored **locally**. No information is sent to external services unless you explicitly configure notifications or integrations.
To further secure your installation:
- Run it behind a reverse proxy with authentication
- Use firewalls to restrict access to the web UI
- Regularly update to the latest version for security patches
See [Security Best Practices](https://github.com/jokob-sk/NetAlertX/security) for more details.
## β FAQ
**Q: Why donβt I see any devices?**
A: Ensure the container has proper network access (e.g., use `--network host` on Linux). Also check that your scan method is properly configured in the UI.
**Q: Does this work on Wi-Fi-only devices like Raspberry Pi?**
A: Yes, but some scanners (e.g. ARP) work best on Ethernet. For Wi-Fi, try SNMP, DHCP, or Pi-hole import.
**Q: Will this send any data to the internet?**
A: No. All scans and data remain local, unless you set up cloud-based notifications.
**Q: Can I use this without Docker?**
A: Yes! You can install it bare-metal. See the [bare metal installation guide](https://github.com/jokob-sk/NetAlertX/blob/main/docs/HW_INSTALL.md).
**Q: Where is the data stored?**
A: In the `/config` and `/db` folders, mapped in Docker. Back up these folders regularly.
## π Known Issues
- Some scanners (e.g. ARP) may not detect devices on different subnets. See the [Remote networks guide](https://github.com/jokob-sk/NetAlertX/blob/main/docs/REMOTE_NETWORKS.md) for workarounds.
- Wi-Fi-only networks may require alternate scanners for accurate detection.
- Notification throttling may be needed for large networks to prevent spam.
- On some systems, elevated permissions (like `CAP_NET_RAW`) may be needed for low-level scanning.
Check the [GitHub Issues](https://github.com/jokob-sk/NetAlertX/issues) for the latest bug reports and solutions and consult [the official documentation](https://jokob-sk.github.io/NetAlertX/).
