Hey everyone! 👋 I'm Jashan, and I'm really excited to finally share DevToolkit. The idea came from a simple frustration—I was constantly switching between different websites just to format JSON, decode a JWT, convert timestamps, or generate code from JSON. I wanted one place that was fast, clean, and didn't require signing in or sending my data anywhere. So I started building DevToolkit. Right now it includes tools like JSON Formatter, JWT Decoder, Base64 Encoder/Decoder, Unix Timestamp Converter, and a JSON to Code Generator with support for multiple languages. Everything runs directly in your browser for speed and privacy. This is still just the beginning. I'm planning to add many more developer tools and keep improving the experience based on feedback from real developers. I'd genuinely love to know: What's one developer tool you use all the time that you'd like to see added? Thanks for checking out DevToolkit and for any feedback you share—it'll help shape what I build next. 🚀

Love that everything runs locally in the browser, no sign-up wall in sight. The no-clutter approach makes it feel like a tool built by someone who actually uses these utilities day to day.

 Thanks so much! That was exactly the goal. I wanted DevToolkit to feel like a collection of tools developers could open, use instantly, and close—without accounts, unnecessary ads, or sending data to external servers whenever possible. Really appreciate you taking the time to try it!
