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! 🚀

Aliens PacMan

This is a submission for the Web Game Challenge, Build a Game: Alien Edition

What I Built

I created a classic PacMan game but with an alien flavor. The player must collect all the points in the map before any alien catches the player.

Demo

You can try the demo in Aliens PacMan Github Pages
and see the source code in the public repository

Journey

Since I wanted to deliver something because in previous challenges I ended up running out of time, this time I opted for something quicker and simpler.

I started by looking at some youtube videos to get inspiration on how to build a PacMan using just html/css/js, and after a couple of different tutorials (mainly https://www.youtube.com/watch?v=YBtzzVwrTeE), I created my own version.

The part of the game that was more challenging, was when thinking of different algorithms for the aliens to move across the map.
I think that if I wanted to release this game, it would still need a twist, since there are some situations where they act anything but smart. But for this challenge, I think it's enough as it is.
