Hi Product Hunt community! 👋 I got tired of shifting between dozens of bloated, slow, and tracking-heavy websites just to do simple tasks like decoding a JWT token, testing a regex, or formatting a chunk of SQL. Many of those tools send your sensitive text to a backend server, which is a massive privacy risk. That’s why I built this DevTools Hub. 🚀 What makes it different: 100% Client-Side & Private: Your logs, tokens, and data never touch any server. Everything runs safely inside your browser. Blazing Fast: Powered by Next.js 15 and Tailwind v4 with aggressive dynamic loading. Offline-First (PWA): Install it as a desktop or mobile app and use all 75+ tools completely offline. Power-User UX: Features an instant Command Palette (Ctrl+K) for navigation and a persistent Scratchpad drawer to keep your clipboard history safe between tools. It's completely free, and I’m dedicated to adding even more utilities. I would absolutely love to hear your feedback, feature requests, or any tools you’d like to see added next! Thank you! 🙌
