What It Does

Problem: Running 15+ projects in ~/Sandbox, each with docker-compose, and manually tracking which ports are in use? Constant conflicts.

Solution: portman auto-assigns ports from predefined ranges and prevents collisions:

portman new myapp        # Auto-assigns: frontend:3000, backend:8000, postgres:5432, redis:6379, langfuse:3200
portman list             # View all assigned ports across all projects
portman check            # Detect conflicts (should never happen)
portman scan             # See what's actually listening on your Mac/Linux/WSL2
portman export myapp     # Copy-paste docker-compose ports snippet

---

Installation

cd ~/Sandbox/portman
bash install.sh
source ~/.zshrc    # or ~/.bashrc, ~/.bash_profile, etc.

Then:

portman --help
portman new myproject

Registry Location

All port assignments are stored in:

~/.portman/registry.json

This is a global file shared across all projects, persists across terminal sessions, and is auto-created on first run.
