Hey Product Hunt! 👋 I'm Mohammed Elmahdy, the maker of DevLite. As a Solution Architect, I constantly found myself pasting highly sensitive data—JWTs, proprietary JSON payloads, database connection strings, and server logs—into random, ad-riddled web tools just to format or decode them. It’s a massive security risk, and frankly, a terrible UX. So, I built the tool I wished existed. DevLite is a 100% offline, zero-backend utility ecosystem. It runs entirely entirely in your browser. Once it loads, you can turn off your Wi-Fi, and every single tool still works at lightning speed. Here is what’s under the hood: 🔒 Privacy by Design: Zero external API calls. Your data never leaves your machine. ⚡ .NET WASM Engine: Heavy cryptographic tasks (RSA/AES generation) and complex AST parsing run at near-native speeds natively in the browser. 🛠️ 20+ Tools: Everything from CIDR Subnet Calculators and Cron Generators to JSON Formatters and Hash Generators. 📌 Personalized Workspace: Pin your most-used tools to the top to create your own custom dashboard (saved via local storage). 📱 PWA Ready: Install it as a standalone app on your OS. I built this to be the ultimate safe sandbox for engineers, DevOps, and SysAdmins. I would love for you to try it out, throw your most complex payloads at it, and let me know what tools you'd like to see added next! I’ll be here all day answering questions about the .NET WASM/React architecture. Cheers! 🚀
