Hi everyone! I'm Marcel, the creator of Tiny Dev Tools. I built this because I was tired of using tools that required a login, or send my sensitive data (like JWTs or JSON payloads) to unknown servers just for formatting or decoding. Most online tool collections are ad-heavy and slow. I wanted something fast, private, and beautiful that stays entirely in the browser. What started as a small set of JSON utilities has grown into a massive toolbox of 170+ tools. Key highlights: Total Privacy: Everything runs locally in your browser. Nothing is uploaded. Speed: No network latency. Results appear as you type. Developer Experience: Sleek dark mode, deep links for sharing, and 100% free. Everything is open source (MIT) and built with Next.js 15 & Tailwind CSS v4. I’d love to hear your feedback! Which tools are you missing? What can be improved? Thanks for checking it out! 🧰✨
