I built DevPocket to replace ad-heavy, slow utility sites. It’s a collection of 14 essential tools (JSON Formatter, ROAS Calculator, SQL Formatter, etc.) built with a focus on privacy and speed. Key Features: 🔒 100% Private: Your data never leaves your browser (Audited 100/100). ⚡ Ultra Fast: Vanilla JS architecture with zero trackers. 📱 Responsive: Modern Bento-grid UI that works on any device. 🛠️ Precision Logic: No floating-point errors in our calculators.
