Gretl is a port manager for developers. It sits in your menu bar, watches every port on your machine, and lets you name, group, start, stop, and share them — so "what's running on 3001?" is never a mystery. Works standalone or alongside your existing tools. Ships with a CLI (gr list, gr start), a Python/Ruby/Node SDK, and a gr.toml you can commit so teammates get the same setup automatically.

Launch websites with enterprise needs at startup speeds.

Hey PH! I built Gretl after losing too much time asking "what's on port 3000?" mid-sprint. The core idea: every port on your machine gets a name, a group, and optionally a start command — so your whole stack is one gr start away. The menu bar app and CLI share the same config, so whatever you set up in the UI is immediately available in scripts and CI. A few things I'm especially proud of: Auto-detect scans your running ports and suggests names from the process + working directory gr.toml lets you commit your port layout so new teammates get it automatically SDKs for Node, Python, and Ruby so you can orchestrate services in tests Would love to hear what groups/workflows you'd use this for — and happy to answer anything!
