Introducing a developer toolbox.

One more in an ocean of toolboxes.

I’ve always wanted to develop my own toolbox. I have never been truly satisfied with the product out there.

A free toolbox, without ads, no cookies, fully client-side, lightweight and no registration needed!

This toolbox is designed to be simple, efficient, and respectful of your privacy. It’s fully client-side, meaning all processing is done in your browser without the need for server-side interaction.


  • Lightweight: Optimized for speed and efficiency.
  • No Ads or cookies: Enjoy an uninterrupted experience without tracking.
  • Fully Client-Side: Your code and data stay on your machine, ensuring privacy and security.
  • Versatile Tools: Includes a variety of tools useful for developers regardless of different languages and frameworks.

I have open-sourced it at so that multiple contributors can participate in making it a complete toolset.
