UpDog - Dev Monitor

UpDog is a lightweight macOS menu bar application that monitors the health of your local development environment. Instead of manually checking if Docker is running, your database is up, or your API server started correctly, UpDog shows you everything at a glance with simple color-coded status indicators.

Key Features

• Menu Bar Status — See overall health instantly: green (all good), yellow (degraded), or red (something's down)
• Multiple Check Types — Monitor TCP ports, HTTP endpoints, Docker daemon, Docker containers, PostgreSQL, Redis, Kubernetes clusters, Elasticsearch, Kafka, RabbitMQ, and more
• Custom Commands — Run any shell command as a health check for maximum flexibility
• Profiles — Create different monitoring profiles for different projects and switch between them instantly
• Low Overhead — Runs quietly in the background with minimal resource usage
• Native macOS App — Built with Flutter, feels native, lives in your menu bar

Supported Health Checks

• TCP port connectivity
• HTTP/HTTPS endpoint status
• Docker daemon and container status
• PostgreSQL database connectivity
• Redis server (PING/PONG)
• Kubernetes cluster connectivity
• Elasticsearch cluster health
• Kafka and RabbitMQ message queues
• SSL certificate expiration
• Disk space thresholds
• Process monitoring
• WebSocket endpoints
• Custom shell commands

Who It's For

• Full-stack developers running multiple local services
• DevOps engineers testing infrastructure locally
• Teams with complex local development environments
• Anyone tired of "connection refused" errors from services that aren't running

How It Works

1. Add the services you want to monitor
2. UpDog checks them at your configured interval (default: 60 seconds)
3. View status from the menu bar icon or click to see details
4. Get notified when services go down

UpDog is free and designed for developers who want a simple, reliable way to know their local environment is healthy before they start coding.
