StackDevTools - Free online tools for developers and creators

Hi everyone 👋 I built StackDevTools to simplify everyday developer and user tasks — things like formatting JSON, comparing text, converting JSON to YAML/XML, changing text cases, and even calculating age differences. Most online tools are cluttered or slow, so I wanted to build something that’s simple, fast, and reliable — designed to help developers focus on what matters. StackDevTools is continuously growing — I’ll be adding many more tools soon. I’d love your thoughts and suggestions — what tools should I add next? 💡
