We’ve all been there. You are deep in the debugging zone, you need to quickly format a massive JSON payload, verify a SHA-256 hash, or decode a JWT.
What’s the first thing you do? You Google "JSON formatter online" and click the first link.
For a long time, I did the same. But eventually, I realized how broken this workflow is.
The Problem with Most Online Dev Tools
Most top-ranking developer utility sites suffer from three major issues:
- Privacy Risks: When you paste your company’s JSON data or a JWT into a random online tool, you are often sending that data to their backend server.
- Ad Clutter: Finding the actual "Format" button among 5 different Google Ads is incredibly frustrating.
- Friction: Some tools now ask you to create an account or hit a paywall after 3 uses.
As developers, we need our tools to be invisible. We need them to be fast, secure, and get out of the way.
Building a Client-Side Alternative
I decided to build my own suite of tools where privacy is the default, not a feature.
Enter DevProo — a completely free, zero-friction developer tools hub.
My philosophy for building DevProo was simple:
- 100% Client-Side: Everything runs locally in your browser. Whether you are generating a hash or formatting JSON, your data never leaves your machine.
- Zero Friction: No sign-ups, no logins, no paywalls.
- No Clutter: A clean UI so you can get in, get your result, and get back to your IDE.
What's inside?
Currently, I've built the utilities that I use the most on a daily basis:
- Data Formatting: JSON & JWT utilities.
- Security: SHA-256 and Hash Generators.
- Time: Epoch and Timezone converters.
- UI/UX: WCAG Contrast Checkers and Favicon generators.
I'd love your feedback!
I am actively maintaining this and adding new tools every week.
I’d love for you to try it out at DevProo.co.in and let me know what you think.
What is that one small utility tool you use every day that you'd like me to add to this suite? Let me know in the comments!
