ToolsLab - 50+ Free Developer Tools - Showcase Project

ToolsLab is a comprehensive suite of 20+ professional developer tools that run entirely in your browser. No server processing, no data tracking, no account required. 🎯 The Problem Developers waste time jumping between dozens of websites for simple tasks. Most online tools are plagued with intrusive ads, require registration, or process your data server-side (privacy nightmare). You paste sensitive API keys, JWTs, or private data into random websites hoping they're trustworthy. 💡 The Solution ToolsLab provides a unified platform where every tool runs 100% client-side. Your data never leaves your browser. Built with Next.js 14 and optimized for performance (<1.5s load on 3G), it offers essential utilities like: JSON/SQL/XML formatters with syntax highlighting Base64/URL encoders with file support JWT decoder with signature validation UUID/Password generators with bulk options Hash generators (MD5, SHA256, bcrypt) QR code generator with logo embedding Text diff checker with merge conflict resolution Regex tester with live matching Color picker with WCAG contrast checker And 10+ more tools... ⚡ Key Features ✅ Zero server processing - everything runs locally ✅ No registration or login required ✅ Dark mode with system preference detection ✅ Mobile responsive design ✅ Keyboard shortcuts for power users ✅ Works offline after first load 🚀 What's Next Currently gathering feedback to prioritize the next batch of tools from our roadmap of 50+ utilities.
