Local Port Cheatsheet

Automatically log and quickly open every dev server you run locally

Problem

Developers often run multiple local services whose ports are scattered across terminals, and soon forget which service is on which port. Terminal history is lost after restart, forcing them to dig through project configs or restart. It gets especially messy when juggling several projects, making it hard to find a local page that was running earlier.

Solution

A small menu-bar/tray app that automatically watches new listening ports on your machine and records the associated process and directory. It shows a visual list where you can click to open in a browser or copy the address, with support for aliases, project grouping, and stale-port reminders.

Users

Full-stack and indie developers juggling multiple local projects

MVP

Watch local listening port changes; show port, process name, and working directory; click to open browser or copy URL; add manual aliases; menu-bar resident

Revenue

Free basic version; one-time or subscription for history, project grouping, multi-device sync, and a CLI

Why now

Local dev services are proliferating and AI coding tools make starting them even more frequent, yet the OS offers no convenient port history; an indie can build a lightweight cross-platform tool
