The Browser Company is ending Arc on Mac and Windows on December 22 and moving users to Dia. Here is the timeline and what carries over.
The Browser Company is shutting down Arc, its design-led desktop browser, on December 22, 2026, and pointing users to Dia, its AI-first browser. TechCrunch reported the news on Thursday, and the company has published a farewell page on arc.net setting out the timeline.
How the Arc shutdown unfolds
The wind-down happens in stages. As of October 22, new Arc accounts can no longer be created, and existing members see no other change yet. On November 23, Arc Search on iOS and Android loses its AI features, including Browse for Me, and users can no longer sign in or sync tabs, although the app keeps working as a basic browser.
On December 22, Arc stops working on macOS and Windows. According to the company's page, accounts will be deactivated and personal data deleted within 30 days, and Arc Search will be pulled from the Google Play Store. The latest version of Arc adds an option to export data and a smoother import into Dia.
Why the company says it is moving on
The Browser Company said its priority is security. "Keeping a browser secure takes constant, dedicated work that is only increasing in the age of AI," it wrote, adding that Dia was built to meet current security standards, so its engineering and security teams will concentrate there.
TechCrunch noted that Arc development already stopped in 2025, after the company was acquired by Atlassian for $610 million, and that the company then acknowledged the "novelty tax" and complexity of the product limited mainstream adoption.
What carries over to Dia
The company says Arc's core features come across. Spaces become Profiles that users can swipe between, vertical tabs remain as an optional sidebar layout, and folders are now Pinned Tab Groups. Passwords, bookmarks, extensions and history transfer on import, and those browser features are free in Dia, with the AI optional.
TechCrunch reported that social media reaction was largely disappointed, with many users reviving calls for Arc to be open-sourced. CEO Josh Miller has previously said the company would like to do that someday but cannot meaningfully do so without also open-sourcing the Arc Development Kit, the proprietary SDK that also powers Dia and remains core to the business.
Until December 22, the company says, Arc for macOS and Windows will keep working as usual and receive basic updates.
