Say goodbye to port collisions on localhost:3000 and more with Portless! 🤯

Say goodbye to port collisions and ugly local URLs. Meet Portless - a dev tool that replaces port numbers with stable, named .localhost URLs (for both humans and AI agents!). 🚀

Check it out: https://port1355.dev/

Instead of standard dev commands, simply wrap them with Portless: 

❌ next dev ➡️ http://localhost:3000 
✅ portless myapp next dev ➡️ https://myapp.localhost

Here's why it's a game-changer for local development: 

✨ Zero port conflicts: Portless runs a reverse proxy and auto-assigns random ports under the hood. It works automatically with Next.js, Express, Nuxt, Vite, Astro, and more. 

🔒 Instant HTTPS: One-time setup to auto-generate certs. No more annoying browser security warnings for local testing. 

🌿 Git Worktree Magic: This is the killer feature. If you use linked worktrees, Portless auto-detects the branch name and prepends it as a subdomain! (e.g. fix-ui.myapp.localhost). No config changes needed. 

🏗️ Microservices Ready: Easily organize your apps with subdomains like api.myapp.localhost or docs.myapp.localhost.

You can even set up custom TLDs like .test if you prefer!

If you want a cleaner, zero-headache local dev environment, this is absolutely worth installing (Node 20+ required).
