As a frontend developer, I enjoy building tools that are actually useful in day-to-day life — tools that are fast, clean, and respect user privacy.
That’s why I created Run It Free, a collection of free browser-based tools that work instantly without sign-ups, uploads, or unnecessary distractions.
🚀 GST Calculator
One of the latest tools on the platform is a modern GST Calculator designed for freelancers, businesses, students, and developers.

Why I Built It
Most GST calculators online have a few common problems:
Outdated and cluttered UI
Too many ads and popups
Slow performance
Confusing workflow
Require unnecessary sign-ups
I wanted to build something different:
✅ Free forever
✅ Privacy-first
✅ Runs entirely in your browser
✅ No uploads
✅ No sign-up required
✅ Fast and mobile-friendly
The goal was simple: create a clean utility that anyone can use instantly.
