PortMap

A lightweight macOS utility that shows what's listening on your dev ports — and lets you act on it instantly.

Features

Live port list — polls TCP listeners in a configurable range (default 3000–9999) every 1.5 s
Project inference — resolves each process's working directory and walks up to find the nearest package.json, Cargo.toml, or pyproject.toml to show the project name
Copy URL — copies http://localhost:PORT to clipboard
Copy Path — copies the project directory as a shell-escaped path, ready to cd into
Kill — sends SIGTERM to the process
Configurable refresh — Fast (500 ms), Medium (1.5 s), Slow (5 s), or Custom
Zoom — Cmd+= / Cmd+- / Cmd+0, persisted across launches
Window size — remembered across launches

bun install
bun run tauri dev

# Full build (includes .app + .dmg installer)
bun run tauri build

# .app only — skips DMG creation
bun run tauri build --bundles app

Output: src-tauri/target/release/bundle/macos/PortMap.app

Drag into /Applications. On first launch, right-click → Open to bypass Gatekeeper (app is unsigned).

Note: DMG creation requires Automation permission granted to your terminal in System Settings → Privacy & Security → Automation → Finder.
