The Browser Company to sunset Arc browser in December 2026

The Browser Company announced on Thursday that it will sunset the Arc browser on December 22, 2026. The company cited rising security costs in the age of AI as the reason for the decision. New Arc accounts can no longer be created as of Thursday.

Starting November 23, users will no longer be able to sign in or sync tabs on Arc. On the same date, Arc Search on iOS and Android will lose AI features including 'Browse for Me'. Arc Search will also be removed from the Google Play Store. On December 22, Arc will stop working entirely on Mac and Windows. Arc accounts will be deactivated and personal data deleted within 30 days of the shutdown.

The Browser Company claims Dia surpasses Arc in speed, stability, and security benchmarks. Dia will carry over equivalents of several core Arc features including Profiles and vertical tabs. Passwords, bookmarks, extensions, and history will seamlessly transfer to Dia. CEO Josh Miller stated that open-sourcing Arc would require also open-sourcing the proprietary Arc Development Kit (ADK). User reactions on social media were largely disappointed by the shutdown.

The Browser Company was acquired by Atlassian for $610 million in 2025. In 2025, The Browser Company pivoted to AI and its Dia browser, dropping Arc into maintenance mode. The shutdown officially closes a chapter that began in 2025 when the startup stopped active feature development on Arc.
