The Browser Company is officially sunsetting the Arc browser on December 22, 2026, as it pivots resources toward its AI-first browser, Dia.
New account creation has ceased, mobile apps will lose sync and AI features on November 23, and desktop apps will stop functioning entirely in December before user data is purged.
The cost of security and the transition to Dia
The announcement was made on Thursday, and the company said the decision was due to the increasing costs of keeping a browser secure in the new age of artificial intelligence. New Arc accounts cannot be created as of Thursday.
The company was acquired by Atlassian for $610 million in 2025.
Next steps and milestone dates
The termination of the service will be gradual:

- 23 November: The Arc Search mobile app will lose its AI features, such as auto-search. Users will no longer be able to log in or sync tabs, but the app will continue to function as a simple, local program.
- 22 December: Arc will stop working permanently on Mac and Windows computers. Accounts will be deactivated and user data will be deleted within 30 days. On the same day, the Arc Search app will be removed from the Google app store.
Why is it not provided as open source?
Several users have asked the company to make the Arc code freely available to the public. However, the company's CEO, Josh Miller, has previously explained that Arc is based on technology that is also at the core of the new Dia program. If the code were released, the company would essentially be giving away the intellectual property of Dia.
What will apply to the new program?
Dia will incorporate features that users have come to know in Arc, such as different profiles, vertical tabs, and bookmark grouping. Passwords, bookmarks, extensions, and history will be transferred to Dia, while Arc features will remain free with optional use of artificial intelligence.
