Tired of ad-heavy tool sites? Welcome home.
👋 Hey there!
As a developer, I've always been frustrated by one thing:
"Why is it so hard to use a simple tool?"
- Character counter → Watch 10 ads first
- JSON formatter → Sign up required
- Image compressor → 3 files limit, pay for more
So I built something better.

It's not perfect, but I'm constantly improving.
