About Localhoston

What is Localhoston

Localhoston is a macOS desktop application that manages local development servers. It auto-detects over 20 frameworks — including Next.js, React, Vue, Python, and Go — and lets you start, stop, and monitor dev servers with a single click. Each project gets its own custom localhost domain, eliminating port conflicts and terminal commands. Built for designers, PMs, and creators who use AI coding tools but aren't comfortable with the terminal.


Why I built this

Hi, I'm Jongjin.

In 2020, the pandemic hit and I had to close my business. My kid was 2 years old, so I stayed home to take care of him. I was a full-time dad for five years.

By 2025, AI was changing everything. Tech companies were hiring less. I tried to find a job as a technical PM, but no one was looking for someone who hadn't worked in five years. So I decided to build my own thing.

That summer, I found Claude Code — an AI that helps you write code. I made a small website called getclaudecode.com to help people install it. Then I started building a real product.

That's when I ran into a problem.

Every time I was working with the AI, my local server would stop running. I'd have to tell the AI: “The server is not running. This site can't be reached. Please restart it.” Again and again. I knew I could just open a terminal and type npm run dev — but when you're in the middle of working with AI, switching to another window just to type a command is annoying.

And I wasn't the only one. Non-developers — designers, creators, PMs, solo founders — were all hitting the same wall. They'd ask their AI “What is localhost?” or upload a screenshot of an error page, hoping the AI would fix it.

These people didn't need to learn the terminal. They just wanted to build their app.

So I built Localhoston — to fix this for all of us, and to stop wasting tokens on “please restart the server.”

You drop your project folder in. You press play. And it works.
