The Browser Company sunsets Arc browser, directing users to Dia by December 2026
The Browser Company, acquired by Atlassian for $610 million, will discontinue its Arc browser on December 22, 2026. The move prioritizes resources for its AI-focused successor, Dia, which the company claims offers superior security and stability. Users have two months to migrate their data, with new account creation halting immediately and mobile AI features disabling in November. This consolidation marks the end of Arc’s independent development cycle.

The Browser Company has officially set a sunset date for its flagship Arc browser, ending its development cycle on December 22, 2026. The company, which was acquired by Atlassian for $610 million last year, is shifting its entire engineering and security focus to Dia, a new browser designed with AI integration and modern security standards in mind. The decision follows a period where Arc development had stalled, with the company previously acknowledging that its resources were better allocated to its successor.
The transition will occur in stages. Starting immediately, new users can no longer create Arc accounts. On November 23, 2026, mobile users on iOS and Android will lose access to AI features such as 'Browse for Me' and will no longer be able to sync tabs. The final phase on December 22 will see the desktop versions of Arc for macOS and Windows become inaccessible, Arc accounts deactivated, and the Android version of Arc Search removed from Google Play.
The Browser Company emphasizes that migrating to Dia is designed to be seamless, with passwords, bookmarks, extensions, and browsing history transferring automatically. The company asserts that Dia now outperforms Arc in stability, speed, and security, and that the AI features in Dia are optional. For users who prefer an alternative to Dia, the Zen browser is frequently cited as a viable option for those seeking an Arc-like experience.
