A 15-minute life-circle evaluation platform: query a residential area, fetch surrounding POIs, compute a weighted life-circle score and generate a Markdown/HTML report — all in the browser. You need your own Amap (Gaode) "Web Service" API key, entered in the in-app settings page (no keys are bundled); an optional DeepSeek API key enables AI reports.

A self-hosted dashboard plus a bundled collector. Devices are listed as plain cards (status dot, name, address, one live line of CPU/memory/GPU); tap "基本信息" on a card to open a dedicated detail screen with live metrics, per-partition disk usage and the full hardware info — the same layout on every screen size. One node is online out of the box (the app's own collector, running inside the Lazycat container — resource figures are container-view). Download the collector from the dashboard to install on your other computers; each device's port can be set or changed in the ⚙️ settings panel (default 8080; existing devices are editable); each machine's online state, CPU/memory/disk usage and GPU utilization (read directly on NVIDIA / AMD; Intel iGPUs report clock occupancy; some legacy drivers expose nothing — the dashboard says so instead of showing 0%), hostname, OS, CPU model, display name and resolution, and LAN IP all land in one dashboard, and all data stays inside your LAN.
