Privacy isn't a feature. It's the foundation.
Umbra blocks ads and trackers before they load, isolates every tab, strips tracking parameters, and encrypts your browsing history — all without slowing you down.
Built from the ground up for privacy — not bolted on as an afterthought.
50,000+ rules compiled directly into the WebKit engine. Ads and trackers are blocked before they even load — not just hidden.
Every tab gets its own ephemeral data store. Cookies, cache, and storage are wiped when you close a tab. Sites can't track you across sessions.
Canvas noise, WebGL renderer spoofing, and navigator property normalisation make your browser harder to fingerprint across sites.
Your bookmarks and browsing history are encrypted with AES-256-GCM. The key lives in your system keychain — never on disk in plaintext.
Every connection is automatically upgraded to HTTPS. If a site can't support it, you're warned before you proceed.
Tracking parameters like utm_source, fbclid, and gclid are stripped from every URL before the page loads.
Strip away clutter and read articles in a clean, distraction-free dark view. One click, any page.
DNS queries go over HTTPS to Cloudflare, Google, or Quad9 — your ISP can't see what sites you're looking up.
Built-in download manager with progress tracking, file chooser, and reveal-in-finder support.
Umbra isn't a Chromium fork with an ad blocker bolted on. It's built on WebKit — the same engine as Safari — with privacy engineered into every layer.
Native apps built for each platform. No Electron. No bundled Chromium. Just a fast, lightweight browser that respects your system.
