Home Network Inventory is a

Home Network Inventory is a self-hosted web application for tracking devices on a home network. It stores information about devices, their network interfaces, IP addresses, Wi-Fi networks, physical ports, credentials, services, and connections between devices.

Supports multiple homes — an apartment, a country house, an office — each with its own isolated inventory.

Designed to be simple enough for a home lab, but structured enough to keep the inventory clean and searchable.
