I built a Privacy Scanner & Freelance Calculator as a PWA (Open Source)

Hi everyone! 👋

I'm Federico, a developer from Italy. I've been working on optimizing my personal site and decided to turn it into a fully installable PWA (Progressive Web App).

Instead of just a blog, I wanted to build useful client-side tools that run directly in the browser without sending data to a server.

I'd love your feedback on the suite I've built so far:

1. NetGuard: A browser fingerprinting and IP leak detector (it checks WebRTC leaks and what your browser reveals)
2. RateMate: A financial calculator for freelancers to estimate net income and taxes
3. PassFort: A client-side password strength auditor

👉 You can check them out here: https://federicosella.com/

Tech Stack:

• Built with Hugo (Static Site Generator)
• Vanilla JS for the tools (no heavy frameworks)
• PWA Manifest for mobile installation
• Hosted on GitHub Pages

If you have any suggestions or spot any bugs, please let me know!

I've developer all of this with the usage of gemini and claude code, please be kind

Thanks for checking it out! 🚀
