I was tired of slow, ad-filled tool websites that upload my data to their servers just to format a JSON file.
So I built VelnoxLabs — 51 free browser-based tools that run 100% in your browser. No sign-up. No server upload. No tracking.
Here's what's inside:
Developer Tools
- JSON Formatter & Validator
- cURL to Python Requests Converter
- Cron Expression Generator
- UUID v4 Generator
- Base64 Encoder & Decoder
- JWT Decoder
- And many more...
Everyday Tools
- Image Resizer
- Word Counter
- Age Calculator
- BMI Calculator
- Tip Calculator
- Invoice Generator
Tech Stack
- Next.js (App Router)
- TypeScript
- Tailwind CSS
- Deployed on Vercel
Everything runs client-side. Your data never leaves your browser.
