We’re a small team that believes software should work for you, not against you.
Zozimus Technologies started with a simple frustration: every browser extension we tried either harvested our data, locked features behind paywalls, or required an account just to block a website.
So we decided to build our own. Extensions that are genuinely private, completely free, and open source. No strings attached. No dark patterns. Just tools that do exactly what they promise.
Every line of code we write runs locally in your browser. We don’t operate servers, collect analytics, or even know how many people use our extensions. And that’s exactly how we like it.
A full image editing toolkit in the browser sidebar — crop, resize, 16 filters, and 12 creative effects. Zero dependencies.
Simple, reliable website blocking with child safety protection. Our first extension built on the principle of privacy by default.
Born from the belief that useful software doesn’t need to spy on its users. We started building tools we’d actually want to use.
We don’t collect data. Not because regulations require it, but because we believe your browser is your personal space.
We use vanilla HTML, CSS, and JavaScript. No frameworks, no build tools, no dependencies. The result is faster, smaller, and more transparent code.
No premium tiers, no subscriptions, no “upgrade to unlock” banners. Every feature is available to everyone, always.
All our code is public on GitHub. We believe transparency builds trust — and trust is earned, not assumed.
We keep everything free. If you find our tools useful, a small donation helps us keep going.
