About Me
I'm a Belgium-based developer who's been building stop-it since 2014 — a free, browser extension that blocks adult content, phishing sites, and trackers.
After Chrome's Manifest V3 transition forced a full technical rebuild in 2024, I've spent the past year growing it back from scratch, now protecting 2,000+ active users across Chrome and Opera.
No tracking, no data collection, no accountability-partner gimmicks — just a lightweight tool that does one job well.
Currently focused on organic growth, real user feedback, and building a sustainable premium tier.
