MiniToolDesk: The 100% Private, Client-Side Developer Toolbox

Hey Product Hunt! 👋 I'm the maker behind **MiniToolDesk**. Like many engineers, I use browser utilities dozens of times a day — whether it's formatting an unruly JSON payload, tweaking a subtle CSS box shadow, or debugging an authentication JWT. Over time, I grew frustrated with two huge problems in almost every tool out there: 1. **The Privacy Risk**: Most web utilities silently transmit your raw data to their backend servers. When dealing with production error logs, customer PII, or internal tokens, pasting code into random online sites is a massive corporate security risk. 2. **Ad Fatigue & Clutter**: Slow-loading pages plastered with intrusive ads and popups that constantly disrupt your flow state. So I built **MiniToolDesk**: ⚡ **100% Client-Side Sandbox**: All computations (JSON formatting, Base64, WebCrypto hashing, Regex, JWT parsing) run entirely in your local browser sandbox. You can literally disconnect your WiFi and the tools still work. Zero server uploads, zero data collection. 🎨 **Visual & Instant**: Interactive sliders for CSS Box Shadows, Glassmorphism, and Gradients with smooth 60fps real-time previews. 🌍 **Native in 7 Languages**: Fully localized in English, Japanese, German, Spanish, French, Portuguese, and Simplified Chinese. 💻 **Open-Source Core**: Powered by our open-source SDK (`minitooldesk-core` on GitHub and npm). MiniToolDesk is 100% free with no signups, no paywalls, and no corporate tracking. It’s built to sit comfortably in your bookmarks bar as a quiet, trustworthy daily companion. I'd genuinely love to hear your feedback, thoughts, or critique! 👉 **What developer utility would you love to see added next?** Thank you for checking it out! 🚀
