After getting tired of bookmarking dozens of online tools for basic dev tasks, I decided to build my own comprehensive solution. Here's Developer Tools Hub!
🛠️ What's Inside
Core Utilities:
- JSON formatter, validator & converter
- Base64 encoder/decoder with file support
- JWT token decoder with payload visualization
- Hash generator (MD5, SHA-1, SHA-256, SHA-512)

💡 Key Learnings
- Client-side processing is crucial for developer tools (privacy + speed)
- Mobile-first design matters (devs code on phones too!)
- Comprehensive testing prevents production bugs
- Performance optimization makes or breaks user experience
🎯 What's Next
Planning to add:
- Code formatters for more languages
