The Browser Company to shut down Arc browser on December 22, 2026 and move users to AI-first Dia
The Browser Company, now owned by Atlassian, announced on 2026-10-22 that it will sunset its Arc browser on December 22, 2026 and direct users to Dia, its AI-first browser. The company cited the rising cost of keeping a browser secure in the age of AI and said its engineering and security teams will focus on Dia. This is product and business news with no direct threat or vulnerability, but Arc users will be left without a supported browser after the cutoff.
Detalhes técnicos

- On December 22, 2026, Arc stops working on Mac and Windows. Accounts are deactivated and personal data is deleted within 30 days. Arc Search is removed from the Google Play Store.
- Arc and Dia both run on the proprietary Arc Development Kit (ADK). The CEO said this is why Arc cannot be meaningfully open-sourced.
Remediação
- Arc users should migrate to Dia or another supported browser before December 22, 2026. Passwords, bookmarks, extensions and history transfer to Dia.
- After the shutdown Arc will receive no security updates, so it should not be used as a primary browser.
