The Arc browser shutdown is scheduled for Dec. 22, 2026, as The Browser Company shifts its engineering and security resources to Dia. The company announced the decision on Oct. 22, ending development and support for its once-popular browser.
The company cited rising security demands as a major reason for the move. It says Dia was built to meet newer security requirements and will become its primary browser.
Arc Browser Shutdown Timeline and User Data
The closure will happen in three stages. New Arc account registrations ended Oct. 22, although existing desktop users can continue browsing until December.
On Nov. 23, Arc Search will lose AI features, including Browse for Me, on iOS and Android. Users will also lose account sign-in and tab synchronization, although basic mobile browsing will remain available temporarily.
On Dec. 22, Arc will stop working on macOS and Windows. Accounts will be deactivated, and associated personal data will be deleted within 30 days. Arc will also be removed from Google Play.
Users can transfer passwords, bookmarks, browsing history and extensions to Dia before the deadline. Arc’s Spaces become Profiles, while vertical tabs remain available through an optional sidebar. Pinned tabs and folders also carry over.
The company says these familiar browser features will remain free in Dia, with optional AI functionality.
Why The Browser Company Is Moving to Dia
The shutdown has disappointed some users, prompting renewed discussion on X about Arc’s future. The browser had developed a dedicated following because of its distinctive interface and productivity features.
Calls to preserve the browser have also circulated within its community, including earlier user commentary.
CEO Josh Miller previously addressed open-source requests in a May 2025 letter. He explained that Arc depends on the proprietary Arc Development Kit, which also powers Dia. Releasing that technology could expose intellectual property central to the company’s business.
The shift follows Atlassian’s $610 million acquisition of The Browser Company in 2025. TechAmerica.ai previously examined Arc, Dia and competing browsers as AI-powered alternatives gained attention.
The company stopped active Arc feature development in 2025 after finding that its complex interface limited mainstream adoption. With Dia now its sole focus, Arc users must export their information or migrate before December’s deadline.
