Blink

Blink is a menu bar utility for macOS developers that monitors your running dev servers and iOS simulators.

Features

• Live server monitoring — see every dev server running on your machine with port, framework, and project name
• Framework detection — automatically identifies Next.js, Vite, Nuxt, Remix, Astro, Django, Flask, Rails, and more with brand-accurate colors
• Simulator tracking — lists all booted iOS simulators with device name and runtime version
• Simulator focus — click a simulator to bring its window to the front, even if minimized
• One-click actions — kill a server, shut down a simulator, or stop everything at once
• Open in browser — jump to localhost from any server entry
• Copy to clipboard — click any port to copy the localhost URL
• Menu bar presence — always know how many services are running at a glance

How It Works

Blink polls every few seconds using standard macOS tools:

• Port scanning — lsof to find listening TCP ports
• Framework detection — inspects process arguments and working directory
• Project names — reads package.json, Cargo.toml, or falls back to the directory name
• Simulators — xcrun simctl for booted simulator data

No background daemons, no elevated permissions, no network access. Everything runs locally.

Tech Stack

• SwiftUI with MenuBarExtra
• Swift concurrency (async/await, TaskGroup)
• @Observable for reactive state
• macOS 14+ (Sonoma)
