Arc is a modern web browser developed by The Browser Company that reimagines the browsing experience with a focus on productivity, organization, and design. It solves the problem of tab overload and browser clutter by replacing the traditional tab bar with a sidebar-based workspace system where tabs are organized into spaces, pinned as favorites, or automatically archived after a configurable period. Arc treats the browser as an operating system for the web, providing built-in tools for note-taking, screen capture, and site customization that reduce the need for separate productivity applications.
Arc features a vertical sidebar for tab and bookmark organization, Spaces for separating different contexts like work and personal browsing, automatic tab archiving to prevent tab accumulation, split-view for displaying multiple pages simultaneously, Boosts for customizing the appearance of any website with custom CSS and JavaScript, a built-in notepad and easel for quick notes and whiteboarding, an integrated media player, command bar for keyboard-driven navigation, and Profiles for managing multiple accounts. Arc also provides an Air Traffic Control feature for routing specific links to designated Spaces automatically.
Arc is designed for knowledge workers, developers, designers, and power users who spend significant time in the browser and want a more organized, distraction-free browsing experience. It is available for macOS, Windows, iOS, and Android, and supports Chrome extensions for compatibility with existing tools and workflows. Arc is particularly popular among developers who appreciate its keyboard-driven interface, designers who value its aesthetic refinement, and professionals who juggle multiple projects and need strong organizational tools to manage their browsing context across different workstreams.
Maintenance-mode note: The Browser Company shifted its active development focus away from Arc toward a new AI-first browser, Dia, in 2025, and the company was acquired by Atlassian in October 2025. Arc still receives Chromium-based security updates and remains fully usable, but it is no longer getting new features, and no official sunset date has been announced. Users planning long-term workflows around Arc should track this status rather than assume continued active investment.
