A single-user, self-hosted dashboard that brings together Habit Tracking Analytics, Fitness & Health Analytics, Homeserver Monitoring, and a Tech-Minimalist AI Chat into one unified interface.

Built with Next.js 16 (App Router + Turbopack), React 19, Tailwind CSS v4, shadcn/ui (Base UI base-nova), Drizzle ORM, PostgreSQL, and Recharts, the dashboard embraces a dense, terminal-inspired design focused on clarity, speed, and resilience.

✨ Features

📊 Habit tracking analytics with streaks, trends, and achievements

🏃 Fitness analytics powered by Intervals.icu

🖥️ Homeserver monitoring with telemetry and uptime metrics

🤖 Terminal-inspired multi-model AI chat

🔒 Cloudflare Zero Trust + origin verification

📱 PWA support with mobile home screen icons

⚡ Graceful degradation when external services are unavailable

🧭 Architecture

The dashboard is built around five core design principles.

Principle

Description

Tech-Minimalist UI

Flat dark theme, strong typography, minimal chrome, and clear visual hierarchy.

Resilient Degradation

Pages use Promise.allSettled() so individual service failures never take down the entire dashboard.

Lazy Database Initialization

Drizzle establishes connections only on the first query, preventing startup failures when PostgreSQL or environment variables are unavailable.

Power-Window Awareness

The homeserver is recognized as ASLEEP or TRANSITION outside configured schedules instead of being reported as offline.

Local Data Mirroring

Intervals.icu activities are mirrored into PostgreSQL, enabling advanced analytics without API rate-limit concerns.

🔒 Security

The application uses multiple layers of protection.

Allows direct access from localhost, LAN, and Tailscale.

Redirects unknown hosts to the canonical domain.

Validates the Cloudflare origin-secret header.

Prevents direct access to the underlying Vercel deployment.
