The Problem
Last year, WatchTowr Labs discovered something terrifying: jsonformatter.org and codebeautify.org exposed 80,000+ credentials.
AWS keys. Database passwords. SSH recordings. All leaked because these "free tools" stored user data on their servers.
The Solution
I built PinusX DevTools — a JSON/YAML toolkit that runs 100% client-side.
Your data never leaves your browser. No server. No storage. No risk.
What It Does
- ✅ JSON Formatter
- ✅ JSON Validator
- ✅ YAML Formatter
- ✅ JSON ↔ YAML Converter
- ✅ JSON Diff
Tech Stack
- React 18 + Vite
- Monaco Editor (same as VS Code)
- Tailwind CSS
- Hosted on Vercel
Why Client-Side Matters
Every character you paste stays in your browser. Open DevTools, check the Network tab — zero requests to any server.
This is how developer tools should work.
What's Next
I'm using this as a foundation to test demand for other developer tools:
- Webhook testing
- API monitoring
- Schema validation
