The team behind Arc has decided to sunset the browser on December 22, 2026. The company says the decision was difficult, citing pride in the Arc community and a priority on security. Keeping a browser secure requires constant work, and that work is increasingly demanding in the age of AI. Engineering and security teams will now focus on Dia, which was built from the ground up to meet today's security standards.
To ease the transition, the company says passwords, bookmarks, extensions and history will move to Dia seamlessly. Spaces, Folders and Tab Groups import with data intact, and Spaces are now called Profiles. Dia is described as surpassing Arc benchmarks in stability, speed and security. Its browser features are free, and AI features are optional.
The timeline begins October 22, 2026, when new Arc accounts can no longer be created. On November 23, Browse for Me and other AI features will be disabled on iOS and Android, and Arc Search will stop syncing tabs. On December 22, Arc will no longer work on macOS or Windows. Arc accounts will be deactivated, and personal data will be deleted within 30 days. Arc Search for Android will also be pulled from the Google Play Store.
Users can import their Arc data into Dia in a few clicks during sign-up, or at any time before December 22, 2026, from the import option in the Dia menu. Existing Arc accounts are unaffected until that date, and Dia is free to download at diabrowser.com.
