NetAlertX

NetAlertX

Self-hosted network visibility and presence scanner that discovers connected devices and alerts on new, unknown, or changed hosts across your LAN/Wi‑Fi.

NetAlertX is a network visibility and alerting service that scans your LAN/Wi‑Fi to discover connected devices and detect presence, reconnections, disconnects, and other changes. It helps you maintain an accurate device inventory and get notified when something unexpected appears on your network.

Key Features

  • Scheduled network scans to detect new, unknown, or returning devices
  • Change detection for device status and network attributes (for example IP changes)
  • Multiple discovery/import methods (such as ARP scanning, DHCP lease import, Pi-hole imports, UniFi controller import, and SNMP router import)
  • Extensible plugin system for custom scanners and integrations, with UI generation support
  • Web UI for device inventory, status history, and network overview
  • Notifications via multiple gateways (including NTFY, Pushover, Pushsafer, and Apprise-supported services)
  • Integrations via API endpoints and webhooks, including smart-home workflows

Use Cases

  • Detect and alert on unauthorized or unexpected devices joining a home or small-office network
  • Presence detection to trigger automations when key devices arrive or leave
  • Build and maintain a lightweight network source of truth and device inventory

Limitations and Considerations

  • Some scan methods (notably ARP-based scanning) may not discover devices across different subnets without additional network setup
  • Low-level scanning can require elevated network permissions depending on the deployment environment

NetAlertX is well-suited for homelabs and small networks where you want straightforward device discovery, change tracking, and actionable alerts. Its plugin and notification ecosystem makes it adaptable to different network setups and automation needs.

Scanopy is a network discovery and documentation platform that scans your environment to identify hosts, services, and how they connect. It generates interactive topology diagrams that stay up to date through scheduled and distributed discovery.

Key Features

  • Automatic discovery of hosts, subnets, and service relationships
  • Interactive topology visualization with customization for clear network diagrams
  • 200+ built-in service definitions to identify common infrastructure and applications
  • Distributed scanning using deployable daemons across network segments and VLANs
  • Docker-aware discovery to map containerized services
  • Multi-user organization management with role-based permissions
  • Change tracking and versioning to compare network state over time
  • Export and sharing options for diagrams and live views

Use Cases

  • Homelab and multi-VLAN network documentation without manual diagram maintenance
  • IT and DevOps inventory and dependency mapping across servers and container stacks
  • Audit, compliance, and exposure reviews by visualizing reachable services and misconfigurations

Limitations and Considerations

  • Some features and collaboration workflows may be oriented toward organizational use (multi-user, roles), which can add complexity for very small setups

Scanopy is well-suited for teams and individuals who want continuously updated network diagrams and documentation generated from real discovery data. It reduces ongoing documentation effort while improving visibility into network topology and exposed services.

SIP3

SIP3

Self-hosted platform for capturing SIP/RTP traffic, analyzing call flows, and monitoring VoIP quality metrics with dashboards and alerts.

SIP3 is a self-hosted VoIP monitoring and analytics platform focused on SIP signaling and RTP media. It captures traffic, reconstructs call flows, and calculates voice-quality and performance metrics to help operators and engineers troubleshoot and assure service quality.

Key Features

  • SIP signaling capture and correlation into call legs/sessions with message-level details
  • RTP/media analysis with common VoIP quality metrics (e.g., jitter, packet loss, latency; MOS where supported)
  • Call flow visualization and drill-down troubleshooting (who-called-who, routing, failures)
  • Search and filtering across calls/sessions for investigations and support workflows
  • Time-series dashboards for QoS/QoE and signaling statistics
  • Alerting/thresholding for degradations and abnormal behavior (implementation depends on stack)
  • Horizontal scaling via collector/receiver components and backend storage

Use Cases

  • NOC monitoring of VoIP/SIP trunks, SBCs, and PBX platforms
  • Root-cause analysis of one-way audio, bad quality, failed calls, and routing issues
  • Capacity planning and SLA reporting using aggregated QoS and signaling metrics

Limitations and Considerations

  • Feature depth (dashboards, alerts, MOS support) depends on the deployed SIP3 stack and configuration; some advanced analytics may require additional components.

SIP3 is suited to telecom/VoIP environments needing packet-based visibility into SIP and RTP behavior. It provides the tooling to move from raw captures to actionable call-centric analytics and ongoing quality monitoring.
