port0

What it does

port0 assigns free ports, injects PORT, and serves your local apps on clean hostnames. Run "port0 npm run dev" Access at: project.localhost, project.web, project.local works for any languages, and frameworks. just wrap it with "port0"

port0 is a lightweight daemon that auto-assigns free ports, injects the PORT environment variable, and reverse-proxies traffic to clean hostnames like project.localhost . No project-level config files required. Port assignment and routing are derived from your working directory automatically. Automatically finds an open port and injects it into your process via environment variables. Say goodbye to port 3000 conflicts. Access your local apps via app.localhost or app.web instead of memorizing messy IP addresses and port numbers. Built-in reverse proxy with WebSocket support and an embedded DNS server. Works seamlessly across macOS, Linux, and Windows. Detects OS/arch, downloads the proper…from port0.bluephantom.dev

  Port Zero – How I learned to stop worrying and love PORT=0Jul 2026 · portzero.net · ▲19

  Hi HN, Recently I wasted several hours wrangling my dev environment only to find out that the browser frontend was talking to the wrong version of the backend. This got me thinking--why on earth are we still using simple numbers to describe which process to connect to? Why not use names instead? I thought of all the times a program wouldn't start because of port conflicts. The more I thought about it, the crazier it seemed. Modern operating systems already offer no-conflict ports: if you make your TCP server listen on port 0, the OS assigns you a random available port. But that only solves…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
