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.
