Hi everyone ๐
I built StackDevTools to simplify everyday developer and user tasks โ 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 thatโs simple, fast, and reliable โ designed to help developers focus on what matters.
StackDevTools is continuously growing โ Iโll be adding many more tools soon.
Iโd love your thoughts and suggestions โ what tools should I add next? ๐ก
