The Browser Company will shut down Arc for macOS and Windows on December 22, 2026, and is directing users to Dia. The company says keeping a browser secure takes continuing work, which is increasing in the age of AI, and that its engineering and security teams will focus on Dia instead. 3
4 If you use Arc, the practical priority is to move or export the data you want to keep before the desktop cutoff.
Why Arc is ending
The company’s stated reason is security and focus: maintaining browser security requires ongoing effort, and Dia was built to meet current security standards. The announcement says the company’s engineering and security teams will concentrate on Dia. 3

That marks a change from simply winding down new features. A report on Arc’s earlier roadmap says the plan in 2025 was to stop adding features while continuing security updates; the 2026 announcement sets a date for the desktop browser and its services to stop working. 36

Arc was described as design-forward, and the company’s farewell acknowledged the community around it. The available sources don’t quantify that following, but they help explain why the end of the product is more than a routine feature freeze for its users. 3

Arc shutdown timeline
| Date | What changes |
|---|---|
| October 22, 2026 | New Arc accounts can no longer be created. |
| November 23, 2026 | Arc Search on iOS and Android loses Browse for Me and other AI features. Mobile sign-in and tab syncing also end. |
| December 22, 2026 | Arc for macOS and Windows stops working, Arc accounts are deactivated, and Arc services are turned off. The company says account-linked personal data will be deleted within 30 days. Arc Search for Android is also set to be removed from Google Play. |
Arc Search is expected to continue working as a mobile browser after its AI features, sign-in and syncing are switched off on November 23. 16 The desktop shutdown is different: the Arc Help Center says the Mac and Windows apps will stop working on December 22, and users will no longer be able to open them to access Spaces, tabs or other browsing data.

What users can do before the deadline
The official migration guide says Dia can import Arc Spaces, Favorites, pinned tabs, folders, bookmarks, history, passwords and extensions. Dia is available on macOS and Windows, and the guide recommends moving before Arc’s December 22 sunset. 19
If you don’t want to move to Dia, reporting on Arc’s export options describes saving tabs as a list of links. Check that the export contains the items you need, and save a separate copy somewhere you can access without Arc. 15
The supplied sources do not establish exactly which basic or security updates Arc will receive before December 22. One report says basic updates will continue, but the official sunset materials listed here don’t specify an update schedule; don’t rely on that as a confirmed commitment. 10

What Dia carries over—and what isn’t confirmed
Dia’s documented importer covers many of the parts of Arc users may want to preserve, including Spaces, pinned tabs, folders and Favorites, as well as browsing data and extensions. 19 The migration guide doesn’t confirm every requested feature or whether each one works exactly as it did in Arc. Claims about Spaces being renamed Profiles, Split View, optional AI use, speed comparisons or pricing aren’t established by the supplied official migration information, so they shouldn’t be assumed from the importer’s feature list.
How Atlassian fits into the shift
Atlassian announced an agreement to acquire The Browser Company on September 4, 2025, describing a goal of building an AI browser for knowledge work. Atlassian later confirmed the acquisition in its October 30, 2025, results announcement. 47
44
That workplace-browser ambition is consistent with The Browser Company’s decision to focus on Dia, but the available sources don’t show that Atlassian ordered Arc’s shutdown. The reason given by The Browser Company is the work of maintaining browser security and its decision to direct engineering and security resources to Dia. 3
4
Bottom line: Arc’s Mac and Windows apps are scheduled to stop working on December 22, 2026. Move to Dia or export the data you want to keep before that date, and don’t assume you’ll be able to retrieve it from Arc afterward. 16
