Meet JustPorts

Every dev server. One clean view.

Run justports from anywhere. It connects open ports to their processes, working directories, and project files so you see useful names instead of anonymous PIDs.

Automatic discovery

Finds active listeners, common web stacks, project names, paths, and launch URLs.

Launch Again

Snapshots useful services as they appear and remembers safe commands for the next session.

Safe service control

Press K to stop the selected service after confirmation and strict PID, user, start-time, and port checks.

One-key navigation

Open the URL in your browser, reveal the project folder, refresh, filter, or relaunch.

The full toolkit

Small tools. Seriously useful.

Each command owns one job, exposes its choices, and starts with defaults that work.

Build & run

Understand projects, processes, and local services without the scavenger hunt.

justports

Dev server dashboard

Discovers running servers, names their projects, opens URLs, remembers launch commands, and safely stops a selected service.

justport

Port inspector

Finds exactly what owns a port and can terminate it with identity checks that protect unrelated processes.

Process cleanup

A clean terminal UI for finding and ending development processes that are hanging around.
