Foxd is a robust, local-first LAN monitoring daemon designed to track device presence and provide real-time notifications. Built with Rust, it passively observes local networks using ARP traffic, DHCP signals, and the Linux neighbor table, ensuring minimal false positives without active probing. Key Features:

• Passive Device Discovery: Continuously monitors your LAN to detect devices.
• Real-Time State Tracking: Maintains an internal state machine for each device, tracking joins, disconnects, and intermittent connectivity.
• Notifications & Automation: Trigger notifications or actions when devices appear, disappear, or violate rules, supporting Telegram, ntfy.sh, webhooks, and API-driven outputs.
• Embedded Web Console & API: Ships with an embedded web UI and REST API for managing devices, rules, and configuration, eliminating the need for an external web server.
• Single Static Binary: Compiles into a single Rust binary, designed to run reliably on Raspberry Pi, home servers, and bare-metal Linux systems.

Foxd emphasizes reliability, low overhead, and local control, making it ideal for environments where these factors are prioritized over dashboards and vendor lock-in. It operates offline, storing device state, rules, and configuration locally, ensuring clean restarts and continuous operation. Developed by P8labs, Foxd reflects a philosophy of creating durable software that integrates seamlessly with other systems while remaining unobtrusive once deployed.
