I Built ExtraTools.dev – Privacy-Focused Dev Tools That Run 100% in Your Browser 🚀

Hey Dev.to! 👋

I recently launched ExtraTools.dev. A set of privacy-focused developer tools that work entirely in your browser. No data leaves your device. No tracking. No ads. Just fast, lightweight, and private tools for everyday developer tasks.

Like many devs, I constantly use online tools for Base64 encoding, JSON validation, or JWT decoding. But I always wondered:

Why do these tools need to send my data to a server?
Why do so many have ads, pop-ups, or trackers?
Why isn’t there a lightweight, privacy-first alternative?
So, I built one. 🚀

What’s Available in ExtraTools.dev?

✅ Base64 Encoder/Decoder
✅ JSON Beautifier & Validator
✅ JWT Decoder
✅ File Extractor (convert files to binary/Base64)

Each tool runs 100% in the browser, ensuring your data stays local.

How It Works

🛠️ Built with Vanilla JavaScript (no unnecessary frameworks).
💡 Leverages Web APIs & Web Workers for better performance.
⚡ Instant Processing (no lag, no network calls).
🕵️ No Tracking, No Ads – Your data is yours.

It’s a small but growing project, and I’d love to hear feedback from the dev community.

What’s Next?

I’m planning to add more tools based on what developers actually need.

What’s missing? What other privacy-first dev tools would be useful? Let me know in the comments! 🚀
