Features

Built for the
terminal generation

Scans every 5 seconds. Zero config. Works the moment you open it.

01

Runtime-aware

Knows node, python, bun, go, ruby, deno, rust. Dev ports surface automatically — no list to maintain.

02

Instant alerts

HUD toast the second a port opens or closes. No permission dialogs. No notification settings.

03

One-click actions

Browser · Finder · Terminal · Copy URL. Everything from the menu. Nothing to type.

04

Deep Docker support

Real container names, Compose stacks, live stats, logs, shell — not just a port number.

05

Knows what to protect

AirPlay on 5000? Handoff on 7000? Flagged in orange. Needs confirmation to kill.

06

No more silent collisions

Port 3000 already taken? Know it before you run. No cryptic errors, no digging through logs.

Docker

Compose-aware.
From day one.

Ports map to container names. Stacks collapse to one line. Everything else is a hover away.

  • group Compose stacks — one line per project, hover to expand all services
  • control Restart · Pause · Stop — without leaving the menu bar
  • logs Container & project logs — opens docker logs -f in your terminal
  • shell Open shell — docker exec -it one click away
  • open Docker Desktop — auto-detected, deep-linked

Arc. Ghostty.
Docker Desktop. Done.

Pick your browser, terminal, and container manager. Add custom port ranges. It remembers everything.
