Zen Browser offers privacy-focused alternative as Arc browser phases out
A new open-source browser modeled on Arc's interface design but without AI features is attracting users displaced by Arc's shift toward AI and eventual discontinuation.
What happened
Atlassian acquired Arc's parent company and redirected development toward Dia, an AI-focused browser, leading to Arc's planned shutdown. Zen Browser, a free and open-source project, replicates Arc's visual design and interface innovations—including a left-aligned tab bar, pinned sites launcher, siloed spaces, and customizable UI mods—while deliberately omitting AI components. In addition to Zen Mods, you can install Firefox extensions. The browser implements a "glance" view feature where links open as temporary pop-over tabs, and has a floating bar activated by Command+T or CTRL+T for launching new tabs, switching tabs, searching, and triggering extensions. Zen currently cannot play DRM-protected video content like Netflix and Spotify, as the Zen Team works to obtain a Widevine license from Google. Firefox's Web MIDI support is also lacking, which affects certain functionality.
Context
Arc's discontinuation leaves users seeking alternatives that retained its design innovations without the AI and data-collection concerns associated with its corporate ownership transition. Zen fills that gap by offering the interface improvements that made Arc distinctive—organizational features and visual freshness—while operating as a volunteer-driven, donation-supported project that does not monetize user data. However, Zen's technical limitations (no DRM support for video streaming services, limited Web MIDI compatibility) mean users may still need secondary browsers for certain tasks. The choice between Zen and Dia represents a split between privacy-focused and AI-integrated browser philosophies for users migrating from Arc.
