LabDeck
Real-time homelab HUD for distributed node visibility, metrics, and operational status.
Overview
LabDeck is a local-first dashboard built to give real-time visibility into distributed homelab nodes. It aggregates Prometheus metrics, service health, and infrastructure status into a clean visual HUD that works offline and prioritizes operational clarity over decorative visual noise.
Technology Stack
Capabilities
- Real-time metrics aggregation
- Service health status display
- Visual status indicators
- Offline-first local caching
- Node-level resource monitoring
- Actionable alerting and status
Implementation
LabDeck is implemented as a Tauri desktop application with a Rust backend and TypeScript frontend. It fetches metrics from local and remote Prometheus endpoints, caches data locally, and renders a visual HUD with color-coded status indicators and quick-action buttons.
Problem
With homelab nodes scattered across multiple machines, tracking system health, service status, and resource utilization became fragmented. Local dashboards required network access, and external monitoring tools added latency and complexity.
