Show HN: Locport – manage localhost ports and prevent conflicts (opens in new tab)

Tiny open source tool that introduces .localhost file convention to keep track of all your local project hostnames and ports, without a need for a proxy.

I was inspired by DHH's Rails World 2025 keynote on how 37Signals currently handles running apps in development. I realized this whole approach can be standardized.

This tool helped me to simplify my local development environment, by dropping a proxy solution, and just utilizing the fact that each app can live on it's own port and have secure context (no need for HTTPS to allow things like copy to clipboard) thanks to modern browsers and .localhost. No need to modify /etc/hosts or anything else, it works out of the box.
