Harbor lives in your menu bar and auto-discovers every local development server running on your machine. No configuration. No setup. Just clarity.
Everything you need to keep track of your development environment, nothing you don't.
Launch Harbor and it immediately finds every dev server on your machine. No config files, no port lists, no manual setup.
Detects Node, Python, Ruby, Go, Rust, Deno, Bun, PHP, Java, .NET, Elixir, and more. If it's listening on a port, Harbor sees it.
Open any server in your browser instantly or gracefully terminate processes with a single click. Complete with confirmation safeguards.
Quickly find servers by name, port, or process ID. When you're juggling multiple projects, search makes it effortless.
Your server list updates every 3 seconds automatically. Start a new dev server anywhere and it appears in Harbor within moments.
Three theme modes — system, light, and dark. Harbor looks right at home on your Mac no matter your preference.
Download the app and drop it in your Applications folder. That's the only setup.
Run your dev servers as you normally would. Harbor watches quietly from your menu bar.
See every running server at a glance. Open in browser or terminate — all one click away.
Stop guessing which ports are in use. Start knowing.
