Hi Product Hunt 👋 I built ToolDeck because I constantly needed small developer utilities like JSON formatters, Base64 encoders or timestamp converters. Most existing tools felt slow, cluttered with ads or required sending data to servers. So I started building a fast, privacy-friendly toolbox that runs entirely in the browser. Key ideas behind ToolDeck: • ⚡ extremely fast (static + CDN) • 🔒 everything runs locally in your browser • 🧰 simple developer-focused tools • 🚫 no signup, no installs Right now it includes tools for JSON, encoding, converters and security utilities — and I'm planning to add many more. I'd love to hear what tools developers use the most so I can prioritize the next ones. Thanks for checking it out!
