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

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.
