🚀 Meet Dev Tools: The Ultimate, Privacy-First Toolkit for Modern Developers

As developers, we’ve all been there—juggling half a dozen browser tabs to encode a string, format JSON, check a regex, or grab a quick UUID. Jumping between multiple sites is distracting. Many existing tools feel cluttered, slow, or send your data off to unknown servers.

I craved a better way—so I built one.

Dev Tools: A fast, privacy-first, all-in-one toolkit with 21+ developer utilities. Everything runs client-side—your data never leaves your browser.

🎯 What is Dev Tools?

Dev Tools is a curated collection of essential developer utilities—beautifully designed, highly performant, and built to maximize privacy. Whether you’re writing frontend, backend, DevOps scripts, or learning new technologies, Dev Tools streamlines your workflow by giving you all the right tools, instantly.

100% Client-Side Processing: No data is ever sent or stored—your code, tokens, and strings stay with you.

Blazing Fast: Built with Next.js 15, React 18, and optimized for real-world speed.

Intuitive Design: Keyboard shortcuts, responsive UI, accessibility, and both light/dark modes make it a joy to use.

💡 Why I Built Dev Tools

I started by using various developer tool websites, but always wanted more—more privacy, more speed, better UX, and tools truly relevant to daily developer needs.

Instead of settling for compromises, I architected Dev Tools with:

An interface that’s easy, familiar, and delightful

Real-world tools—no clutter, just what devs need most

Thoughtful touches—smart button states, error handling, and lightning-fast feedback

Privacy as a core feature, not an afterthought

I didn’t set out to clone existing platforms—I wanted to improve on them and shape Dev Tools into my ideal developer toolkit.
