Every time I searched for a “JSON formatter” or “JSON viewer” I ended up on some old looking site filled with ads, popups, or weird network calls in the background.

I’d paste my data… and then realize -

“Wait, I just gave my JSON file to some random server on the internet.” 😅

As a dev, that didn’t sit right with me. So I decided to fix it for myself.

The Idea

I wanted something that:

  • Works instantly, with zero lag
  • Runs 100% on the client - no backend, no tracking
  • Feels modern, not like a 2010 web tool
  • Lets me explore JSON easily (collapsible, clean, dark UI)
  • Basically - a JSON viewer that respects both privacy and design.
