Arc desktop browser to stop working December 22 as focus shifts to Dia

Arc Search will remain usable as a basic mobile browser, but its AI tools, sign-in and tab syncing will end November 23.

The Browser Company will end operation of Arc’s Mac and Windows versions on December 22, 2026, as it redirects engineering and security staff toward its AI-focused browser, Dia. The company said the decision reflected the increasing cost of maintaining browser security as AI use grows.

Registration for new Arc accounts has closed. The mobile wind-down starts November 23: Arc Search on iOS and Android will lose AI capabilities such as Browse for Me, along with account access and tab synchronization. It will continue to function locally as a basic browser.

The December 22 desktop shutdown will also bring account deactivation, followed by deletion of personal data within 30 days. Arc Search will be withdrawn from the Google Play Store.

For people switching browsers, the company said Dia will support transfers of browsing history, passwords, extensions and bookmarks. It also offers versions of Arc’s browsing environments, vertical tabs and folders. Those Arc features will remain free in Dia, and users will not have to use AI.

Disappointed users renewed appeals on social media for Arc to become open-source. CEO Josh Miller has previously said that a meaningful open-source version would require sharing the proprietary Arc Development Kit, which also underpins Dia and remains central to the company’s value.

Active development of new Arc features ended in 2025, when the company acknowledged that the browser’s complexity had limited broader adoption. Atlassian bought The Browser Company for $610 million that year.
