Arc Browser Is Shutting Down in 2026 as The Browser Company Shifts Focus to Dia
The Browser Company is officially retiring Arc, its design-focused web browser, and moving its full attention to Dia, the company’s newer AI-first browser. Arc will shut down completely on December 22, 2026, marking the end of one of the most distinctive attempts to rethink the modern web browser.
The company said the decision comes down to security, engineering focus, and the growing demands of maintaining a browser in an AI-driven internet era. According to The Browser Company, keeping a browser safe now requires constant work, and those demands are only increasing as AI becomes more deeply connected to how people browse the web.
Dia, the company says, was built from the ground up around current security standards. Because of that, its engineering and security teams will now concentrate their resources on Dia instead of continuing to support Arc.
The shutdown will happen in stages. New Arc account creation has already been disabled. On November 23, Arc Search for iOS and Android will lose its AI-powered features, including “Browse for Me.” Users will also no longer be able to sign in or sync tabs. However, the mobile app will still work as a basic local browser for a limited time.
The final cutoff comes on December 22, 2026, when Arc will stop working on both Mac and Windows. After that date, Arc accounts will be deactivated, and user data will be deleted within 30 days. Arc Search will also be removed from the Google Play Store.
The Browser Company says Dia now performs better than Arc in key areas such as speed, stability, and security. Still, the reaction from longtime Arc users has been mixed, with many expressing disappointment online. Arc built a loyal fanbase thanks to its clean interface, vertical tabs, Spaces, and workflow-focused design, so the shutdown feels like a major loss for many users who preferred it over traditional browsers.
Some users have again called for Arc to become open source, hoping the community could keep the browser alive. However, CEO Josh Miller has previously explained why that is unlikely. Arc is built on the company’s internal Arc Development Kit, also known as ADK, which is proprietary technology and also powers Dia. Open-sourcing Arc in a meaningful way would require releasing major parts of ADK, which remains central to the company’s business.
For users moving from Arc to Dia, The Browser Company says several familiar features will carry over. Dia will include Profiles, which function similarly to Arc’s Spaces, allowing users to separate work, personal browsing, and other environments. Arc’s popular vertical tabs will also remain available as an optional sidebar layout. Folders are being renamed as Pinned Tab Groups.
The transition should be relatively smooth for existing users. Passwords, bookmarks, browser history, extensions, and other key data will be transferable to Dia. The company also says Arc-style features will remain free inside Dia, while AI features will be optional rather than mandatory.
Arc’s retirement closes a significant chapter for The Browser Company. The startup had already stopped active feature development for Arc in 2025, signaling that its long-term plans were shifting. That same year, the company was acquired by Atlassian for $610 million.
Arc gained attention because it tried to break away from the standard browser formula. Instead of simply copying Chrome, it introduced a more organized, workspace-driven browsing experience aimed at power users, creatives, and people who spend much of their day online. Its interface was praised for feeling fresh and thoughtful, but that same originality also made it harder for mainstream users to adopt.
The company has previously acknowledged that Arc’s learning curve and unusual design created what it described as a “novelty tax.” In other words, while dedicated users loved Arc’s new approach, many everyday users found it too different from the browsers they already knew.
In the end, Arc became a cult favorite rather than a true mass-market rival to Chrome, Safari, or Edge. Dia now represents The Browser Company’s next major bet: a browser built around AI, modern security needs, and a more streamlined future for web browsing.
For Arc fans, December 22, 2026, will be the final goodbye. For The Browser Company, it is a clear pivot toward Dia as its main browser platform going forward.
