Arc: sovereignty score and 8 European alternatives

Arc is a Chromium-based desktop browser for macOS and Windows from The Browser Company, installed locally on the user's computer. The company's website now promotes its successor, Dia, and states that Arc receives Chromium updates only, while recommending Dia for active security patches. Organisations should therefore treat Arc as a product in maintenance mode rather than as a current platform.

The Browser Company of New York was acquired by Atlassian, which announced the deal in September 2025 and said the company would continue to operate as a separate business. Atlassian Corporation is a Delaware-incorporated holding company, so both the owner and the browser's developer sit under US jurisdiction. Arc is proprietary software and not open source. A European organisation should treat it as a US-controlled browser and check the privacy terms for data flows before using it with work data; the vendor does not state where Arc data is hosted.

Why digital sovereignty matters with Arc

Arc is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Arc hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Arc is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Arc together with your other vendors and gives a total score, a heatmap and the main risk drivers.
