NEW Lumen 1.5.2 is here

The quiet browser
for your Mac.

Lumen is a minimal, fast browser built on WebKit. It blocks ads and trackers out of the box, and turns off with one click when you need it to.

Free · macOS 14 or later · Apple silicon and Intel · Beta

Why Lumen

Everything you need.
Nothing that gets in the way.

The speed and battery life of WebKit, the engine behind Safari, with the features Safari is missing.

Ads blocked, natively

Ads and trackers are stopped before they load, using WebKit's own content blocker. No extension, no slowdown.

Off in one click

If a site misbehaves, turn the blocker off for that site only. Or everywhere, with ⇧⌘B.

One bar for everything

Addresses, searches, open tabs, bookmarks, history and every command live in a single command bar. Press ⌘L.

Light on memory

Tabs you haven't touched in a while hibernate, then wake up exactly where you left them, history included.

Split view and reader

Put two pages side by side, or turn a cluttered article into a clean, readable page.

Private by default

Tracking removed from links, automatic HTTPS, Global Privacy Control and private windows that forget everything.

Passwords with Touch ID

Lumen saves your passwords in the Mac's Keychain, fills them after Touch ID and suggests strong new ones.

Tab groups

Drag a tab onto another to make a group, or let Lumen tidy tabs from the same site into one.

Sites as apps

Install any site as an app with its own window and Dock icon, kept apart from your browsing.

Lumen Shield

Ad blocking you can actually switch off.

Most blockers are all or nothing. Shield gives you a clear switch for every site, and sensible defaults everywhere else.

  • Works offline. A built-in list covers the biggest ad and tracking networks from the first launch.
  • Community lists. Turn on EasyList and EasyPrivacy for tens of thousands more rules, refreshed weekly.
  • No cookie walls. Consent banners are hidden and the page scrolls again.
  • Fewer YouTube ads. Video ads are stripped or skipped automatically.
  • Third-party cookies blocked. Sites can't follow you around the web.

Clean links

Links without the luggage.

Shared links are stuffed with tags that tell advertisers where you came from. Lumen strips them before the page even loads, so you land on the same page, minus the tracking.

  • Removes utm_, fbclid, gclid, msclkid and dozens more
  • Knows the site-specific ones on YouTube, Spotify, Amazon and X
  • "Copy Link Without Tracking" in every page's menu

Make it yours

Your browser, your colours.

Pick an accent colour, put the sidebar on either side or switch to tabs along the top, float the page with rounded corners, and choose your start page. Try a colour:

  • Window tint that follows each site's colour
  • Your own CSS for any site: hide distractions, change fonts
  • Search shortcuts: type yt lofi to search YouTube

Dusk
Ocean

Questions

Good to know.

Is Lumen free?

Yes. Lumen is free to download and use.

Does Lumen collect any data?

No. There are no analytics and no accounts. Lumen only talks to the sites you visit. If you turn them on, it also downloads filter lists from easylist.to and fetches search suggestions from your search engine. Suggestions are off by default.

Why does macOS warn me when I open it?

The beta isn't notarized by Apple yet. Right-click Lumen.app and choose Open, and macOS remembers your choice from then on.

Which engine does Lumen use?

WebKit, the same engine as Safari. Sites look and behave the way they do in Safari, and you get its speed and battery life.

Can I bring my bookmarks and passwords?

Yes. Lumen imports bookmarks, history and sign-ins straight from Safari, Chrome, Firefox, Opera, Brave, Edge and Arc. Passwords come across from a CSV exported by the Passwords app or your old browser, and are kept in your Mac's Keychain behind Touch ID.

Does it block every YouTube ad?

Most of them, most of the time. YouTube changes its ads often, so some may still get through.
