It was first released in 2023 for macOS and is also available for Windows, iOS and Android. In 2025, a blog post announced that Arc would be sunset and no longer be actively developed, as the company shifted all focus to developing its new AI browser, Dia. Arc is still maintained through Chromium and security updates.
