A lighthouse for your
local servers

Everything you need to keep track of your development environment, nothing you don't.

Zero Configuration

Launch Harbor and it immediately finds every dev server on your machine. No config files, no port lists, no manual setup.

Auto-Discovery

Detects Node, Python, Ruby, Go, Rust, Deno, Bun, PHP, Java, .NET, Elixir, and more. If it's listening on a port, Harbor sees it.

One-Click Actions

Open any server in your browser instantly or gracefully terminate processes with a single click. Complete with confirmation safeguards.

Search & Filter

Quickly find servers by name, port, or process ID. When you're juggling multiple projects, search makes it effortless.

Live Refresh

Your server list updates every 3 seconds automatically. Start a new dev server anywhere and it appears in Harbor within moments.

Light & Dark Themes

Three theme modes — system, light, and dark. Harbor looks right at home on your Mac no matter your preference.
