Serein

A browser that doesn't track you. No ads, no profiling, no distractions.

Private

Your browsing data stays local. No trackers, no servers collecting profiles.

Simple

Clean interface. No clutter, no notifications fighting for attention.

Fast

Lightweight engine. Blocks what slows you down before it loads.

Getting started

Get Serein. Runs on Mac, Windows, and Linux.

Make it your primary browser. Takes 30 seconds.

Everything else is automatic. Trackers blocked, data stays local.

Your data shouldn't be a product

Most browsers track every site you visit, every search, every click—then sell it. Serein keeps that data on your machine.

Ads don't belong in the browser

Tracking pixels, ad networks, behavioral profiling—blocked before they load. The web is faster and cleaner.

Built for actual privacy

Not marketing. Not a privacy theater. Actual privacy: open source, auditable, no servers collecting your activity.

Ads, analytics, profiling networks—all blocked before they connect.

Address bar, tabs, settings. Nothing you don't need.

No bloat. Pages load and respond quickly.

Code is public. Audit it, contribute to it, verify it yourself.

Bookmarks and settings sync across devices. Everything stays encrypted locally.

Tab through everything. No mouse needed unless you want it.

Free and open source. Always will be.
