Similar to Arc, Zen has a non-cluttered interface that mostly stays out of your way and is built around a sidebar that encourages you to keep things simple and organized. Iâm not sure if the design is specifically inspired by the aspects of Arc that people have liked most, or if theyâre just chasing the same goals.
Unlike Arc, Zen is Free-as-in-Libre Software, built on Firefox instead of on Chromium, runs on more platforms (Windows, macOS and Linux), and doesnât require you to sign into a cloud account just to use the browser. And it actually has bookmarks! (It also doesnât have AI features like Arcâs summaries and so on.)
Like Waterfox it removes Mozillaâs existing data collection. It doesnât go as far on privacy as LibreWolf, but itâs notable that Zenâs privacy policy starts out with âInformation We Do Not Collect.â
Connections and Compatibility
It can connect to Firefox Sync (which is encrypted) and is compatible with Firefox add-ons. There are the usual hoops to jump through when you first install it to get native messaging to connect to KeePassXC, unless youâre using running it through Flatpak on Linux, in which case the hoops donât work either (see below).
Zen canât play media locked by Widevine DRM, because the small team canât justify spending the money on the license when there are other things they want to build. (For comparison, LibreWolf rejects DRM support on principle.) If you want to watch Netflix or whatever on your desktop, you can use another browser like Waterfox for it.
As with LibreWolf and Waterfox, not all of the documentation has been copied and updated to be Zen-specific yet, and in some cases it just links straight to the Firefox docs. I do appreciate that the About box tells you both what Zen version youâre using and what Firefox version itâs built on.
Flatpak, AppImage & Linux
When installed using Flatpak, web browsers canât connect over native messaging to KeePassXC. And Zen doesnât actually open the first page when opening a link from another app unless itâs already running. These are both fixed by using the AppImage, but now I need to manually add a zen.desktop
file and icon so itâll show up in the system menu. Then I have to either update the AppImage manually or install another tool to update the AppImage automatically, plus it turns out thereâs another bug where the AppImage Zen opens a new copy of Thunderbird on the rare occasions I click on an email address, which launches a blank profile to avoid conflicting with the already running oneâŠ
I finally ended up just downloading the tarball and pointing zen.desktop
to it. Itâs old-school, but it all works properly!
Availability
Regular installers with updaters for Windows and Mac. Flatpak, AppImage and tarballs for Linux. Both Intel/AMD and ARM on all platforms.
No mobile version. I think the closest comparison would still be Arc Search, but as with the desktop version, Arc isnât Free (just free) or Gecko-based.
