The Open-Source Browser That Wants Your Attention, Not Your Data

Every browser competes for your attention. Most of them quietly compete for your data too - and few are willing to publish their entire source code to prove otherwise.

That is exactly what makes our newest listing worth a look. Zen Browser just joined the Web Browsers section on CODECS.COM, and it arrives with a refreshingly blunt pitch: we care about your experience, not your data.

What Exactly Is Zen Browser?

Zen is a free, open-source browser built on top of Mozilla Firefox. That means it runs on the Gecko engine - one of the last serious alternatives to the Chromium code that powers almost every other browser today.

Visually, it borrows the best idea from Arc: a clean vertical sidebar instead of a crowded horizontal tab strip.

The result feels less like a row of shouting tabs and more like an organized workspace.

Four Features That Actually Change How You Browse

• Workspaces - keep work tabs, research tabs and personal tabs in separate spaces, then switch between them instantly.
• Compact Mode - the interface disappears when you do not need it, giving videos and articles the full screen.
• Split View - put two tabs side by side without juggling windows. Great for comparing specs or following a guide while you work.
• Glance - jump straight to your most-used tabs without digging through history.

Why This Matters for Your Privacy

If you read our breakdown of who's spying and who's protecting you in 2026, you already know the browser market splits into two camps. Zen lands firmly in the protective one.

Because it inherits Firefox's tracking protection and adds no telemetry-driven business model on top, there is simply less of your data in motion.

The browser is one piece of the puzzle, though - pair it with our 5-minute guide to stopping Windows 10/11 data collection and you close the loop at the operating system level too.

Should Chrome Users Switch?

Not necessarily - and we will not pretend otherwise. Google Chrome still wins on raw extension count and web app compatibility, which is why it stays one of our most downloaded listings.

Developers and testers also have a practical reason to keep Chrome around: automation. Tools like ChromeDriver only talk to Chrome, so anyone running Selenium scripts or automated QA cannot walk away from it.

The smart move for most people is both: Chrome for the sites and workflows that demand it, Zen for everyday browsing where privacy and focus matter more.
