I built InSpectre (https://inspectre.cc/), an open-source, self-hosted platform designed to discover, track, fingerprint, and security-scan every device on a local network without relying on third-party cloud services.
As a homelab administrator and sysadmin, I wanted a single dashboard to keep track of active LAN devices, catch vulnerabilities before they become problems, track household presence, and manage container infrastructure without sending telemetry outside my local network.
Key features:
Device Discovery and Fingerprinting: Uses active ARP sweeps combined with a passive ARP/DHCP sniffer to spot new devices immediately. It auto-classifies devices using OUI, DHCP parameters, and port patterns. Security and Vulnerability Scanning: Integrates Nuclei and nmap (-sV) for scheduled CVE scanning per device with a severity-grouped dashboard. Traffic Control and Blocking: Allows you to pause network access or set recurring block schedules per device via ARP MITM. Presence Tracking: Groups multiple devices (phone, laptop, smartwatch) under individual people to provide a unified Home/Away status and per-person schedule controls. Docker and Proxmox Monitoring: Streams logs, scans images with Trivy for CVEs, and manages container updates with automated rollbacks. Integrations: Native Home Assistant MQTT auto-discovery, 16 notification channels (ntfy, Gotify, Telegram, Pushover, Discord, etc.), and custom JSON/YAML plugins.
Architecture: The app runs as four lightweight Docker containers (frontend, backend, probe, and Postgres). By default, zero bytes leave your LAN unless you explicitly configure an external notification integration. It is dual-licensed under AGPL-3.0 and Commercial.

I would love to hear your feedback on the architecture, features, or performance. What tools do you currently use for LAN visibility, and what features would make this more useful in your setup?
