What happened
The Browser Company is shutting down Arc on December 22, 2026, and pushing users to its AI-first browser Dia. New Arc accounts are already blocked; on November 23 Arc Search on iOS and Android loses AI features like “Browse for Me” and sign-in/sync, and on December 22 Arc stops working on Mac and Windows, accounts are deactivated, and personal data is deleted within 30 days. The company says browser security costs are rising, while open-sourcing Arc is blocked because it depends on the proprietary Arc Development Kit that also powers Dia.
Why it matters
If you or your team still use Arc, you have a hard migration deadline: export bookmarks, passwords, and any local workflow data before December 22, because accounts are deactivated and personal data is deleted within 30 days. The open-source request is also concretely blocked by the proprietary ADK shared with Dia, so teams should not plan around Arc becoming community-maintained.
Discussion angle
What is the practical migration checklist for anyone still on Arc, and does the proprietary ADK explanation change how you evaluate AI-browser lock-in for internal tools?
