The Browser Company is sunsetting Arc

The Browser Company announced on October 22, 2026, that Arc browser will be permanently discontinued on December 22, 2026, bringing an end to one of the most innovative and anticipated browsers of the past few years. The decision marks the close of a product that revolutionized browser interfaces and influenced how millions of people navigated the web — but which, in the company's own words, "can no longer keep Arc as safe and secure as it needs to be in the age of AI."

The shutdown does not happen all at once. The Browser Company is following a three-phase wind-down plan that has already begun. As of October 22, new Arc account registrations are disabled. The browser continues to work normally for existing users, but with an inevitable expiration date. On November 23, AI features including "Browse for Me" in Arc Search will be disabled on iOS and Android, and login and tab sync will be shut down. On December 22, Arc for macOS and Windows will stop functioning entirely, accounts will be deactivated, and personal data will be deleted within 30 days. Arc Search for Android will be removed from the Google Play Store and from devices where it is already installed.

Arc's legacy

Arc was launched in 2022 by The Browser Company, a New York startup founded by Josh Miller, a former Tumblr and Yahoo executive. Within a few years, the browser became a cultural phenomenon. Its vertical sidebar interface with tabs on the left, "Spaces" for separating browsing contexts, and deep site personalization through its Arc Boosts tool attracted a devoted user base. Unlike Chrome or Firefox, Arc required users to create an account to function — which made for a more integrated experience but also a more restrictive one.

According to data from The Browser Company itself, Arc never became a mass-market product to replace Chrome. An internal letter from May 2025 revealed that only 5.52% of daily users regularly used more than one Space. The complexity of the interface, which engineers called the "novelty tax," prevented Arc from reaching mainstream audiences. Early users loved it, but the browser struggled to retain broader audiences.

Nevertheless, Arc left an indelible mark on the ecosystem. Its ideas — vertical tabs, context separation, deep personalization — were copied or inspired features in other browsers. Microsoft Edge integrated the vertical tabs concept, Opera added similar features to its main browser, and Firefox experimented with Arc-inspired layouts. The product fulfilled an important role: it showed that the browser, a tool that had barely changed in 15 years, could still be reinvented.

Why Arc is dying

The official reason is security. In a letter published on Arc's website, the company explained that keeping a browser secure "takes constant, dedicated work that is only increasing in the age of AI." Each Chromium update, each newly discovered vulnerability, each sophisticated attack requires a security team to dedicate hours to fix and test. With engineering and security resources focused exclusively on Dia — the company's AI browser — maintaining Arc in parallel became unsustainable.

Dia was announced in June 2025 as Arc's successor. Rather than being an evolution of Arc's interface, Dia was built from scratch with a different architecture focused on integrated AI features. The company claims Dia now surpasses Arc in stability, speed, and security benchmarks, and that all of Arc's core functionality is available in Dia — with AI features being optional.

The acquisition of The Browser Company by Atlassian for $610 million in September 2025 radically changed strategic priorities. Atlassian, known for Jira and Confluence, saw Arc and Dia as opportunities to create a knowledge worker browser, integrating productivity tools with web navigation. Arc, as a standalone product, no longer fit into that plan.

What comes next

For Arc users, the transition to Dia has been facilitated. The Browser Company is offering automatic migration of passwords, bookmarks, extensions, and history to Dia, with an improved import experience. The company is also trying to attract AI-skeptical users, emphasizing that all additional features are optional. However, Dia still does not have Arc's entire feature set, and some users report the experience is not exactly the same.

Josh Miller, CEO of The Browser Company, explained in an interview with Engadget that the decision to not maintain two products in parallel was obvious. "Keeping a browser secure is constant work. It doesn't make sense to keep Arc alive when our focus is delivering the best browser possible," he said. The company also clarified that it will not open-source Arc, because the Arc Development Kit (ADK) — the proprietary SDK powering Arc's engine — is one of the company's most valuable intellectual property assets.

Arc fans' response on social media has been predominantly one of disappointment, with some calling for Arc to be open-sourced so the community can keep it alive. As of now, there are no indications this will happen.

What remains of Arc, for the next two months, is a transition period. Users can export their data, migrate to Dia, or simply continue browsing with whatever browser they already use. For many, Arc will be remembered not as yet another tech product that failed to scale, but as the browser that tried something different — and showed us that the internet's interface can still be reinvented.
