Developer comments
Hi everyone! I built ToolsAid with one simple principle in mind: your data should stay yours.

Like many of you, I was tired of Googling "JSON formatter" or "JWT decoder" and landing on ad-riddled websites where I had to paste sensitive data into a server I didn't trust. That's why I created ToolsAid.

The Core Promise:

100% Client-Side: Whether you are formatting JSON, decoding a JWT, or generating RSA keys, the logic runs entirely in your browser. Your code and data never leave your device.

No Bloat: No ads, no tracking cookies, and no mandatory sign-ups. Just the utilities you need, instantly.


I actively maintain this project and listen to user feedback. If there is a utility you’re missing or a bug you’ve found, please reach out via the support tab. Happy coding!
