I Built a Free JSON Tool for Developers (Because I Was Tired of the Rest)

I don’t know about you, but I’m getting tired of the state of the web for developers.

Every time I search for a quick JSON formatter or validator, I land on a page packed with ads, trackers, and popups. Sometimes it even slows down my browser just trying to load the tool.

Sure, I could use my IDE for that. But it’s often slower and less user-friendly than a lightweight, focused web page.

So I built my own.

It lets you:

✅ Format JSON with proper indentation
✅ Validate JSON in real time with error reporting
✅ Generate TypeScript, Java, Python, or C# models instantly
No ads. No tracking. No friction.
Just a tool my team and I use every day — so I figured, why not share it?

💸 My only costs? A domain name and a small Next.js bill.
But if it saves time and frustration, it’s totally worth it.

🛠️ Built with Next.js, Tailwind, and TypeScript
📬 I’ll share how I built it — and how I kept it lightweight and fast — in an upcoming post.

This also reflects a mindset I’m trying to build inside my company:
👉 When a developer builds something useful for the team, they’re encouraged to make it available to other developers too.

It’s a simple way to turn internal tools into public value — and sometimes, those small tools make a big difference.
