The Browser Company announced it will permanently sunset its flagship Arc browser on December 22, 2026. The move gives current users two months to migrate their browsing setups before the application becomes inaccessible on macOS and Windows and user accounts are fully deactivated. [1][2]
The shutdown process unfolds in stages. Starting immediately, new account creation is blocked. On November 23, mobile apps on iOS and Android will lose sync capabilities, sign-in functionality, and the Browse for Me tool alongside other AI features. The firm is directing users toward Dia, its newer browser, promising free core features, optional AI, and seamless data transfers for passwords, bookmarks, extensions, history, and tab structures.

The developer explained that maintaining browser security requires extensive resources in the AI era, prompting engineering and security staff to concentrate exclusively on Dia. The shift comes as other experimental projects reassess their footprints, such as OpenAI closing down its Atlas browser earlier in the year. [1]
