The Browser Company will close Arc on December 22, deactivating all its user accounts
Anyone who uses the Arc browser daily can now mark the December 22, 2026which is the day the browser will stop working on both macOS and Windows. From that date, accounts will be deactivated and associated personal data will be deleted within 30 days. So, if you are one of its users, it is in your best interest to export what you have saved before the time comes.
As confirmed by The Browser Company in a statement, the decision has to do with security. The company maintains that keeping a browser protected requires constant work. Dia, their latest browser, was built from the ground up to meet today’s standards. That’s why its engineering and security teams will work only on Dia from now on.
In reality, this situation is similar to what we have already seen in other companies. For example, OpenAI launched its own browser, ChatGPT Atlas, in 2025. Just a few months later, it decided to close the project under the same pretext. The difference, however, is that The Browser Company had for a long time maintained two developments that, despite being based on Chromium, is something that absorbs an enormous amount of resources.
A closing in three acts that has already begun
The browser does not go away suddenly. There is still time thanks to the fact that the company has spread the process over three dates. From the October 22 You can’t create new Arc accounts, although for current users nothing changes yet. Of course, the latest version releases an option to export all the data along with a more direct import into Dia.
He November 23 It’s the turn of mobile development, because on iOS and Android Browse for Me and the rest of the AI functions will be disabled. Arc Search will still serve as a browser, but without login or tab syncing. And on December 22, in addition to closing on desktop, Arc Search for Android will disappear from Google Play.
Your Spaces will be renamed Profiles and your Folders will be called Tab Groups
For those who make the leap, the company ensures that passwords, bookmarks, extensions and history travel to Dia during the import. The Spaces become there Profileswith all its information inside, and you change from one to the other by sliding just as you did in Arc. The folders become Tab Groupswhile pinned tabs and favorites arrive with whatever custom names they had. Anyone who misses the vertical column can activate the tabs in the sidebar and hide it with a keyboard shortcut when they need to concentrate.
Regarding Dia, the company itself states that its current browser already surpasses Arc in stability, speed and security. The navigation features used in Arc are available for free, with AI as an optional addition.
We tested it a while ago for our guide to AI browsers, when it only worked on macOS and required you to create an account. Its most characteristic feature was memory, a function that saves what you ask of it and then behaves like a personalized assistant. The team that developed Arc is the same one behind Dia, according to the company, which has also announced that it is preparing new releases for the coming months.
