- What is Arc?
- Arc is a Chromium-based desktop browser from The Browser Company, built around a vertical tab sidebar.
- What does it do?
- Replaces the tab bar with a sidebar, sorts tabs into Spaces per project or profile, and archives ones you stop using. Adds split view, a command bar, and Boosts for restyling individual sites.
- Who is it for?
- People who keep dozens of tabs open and want them grouped by context — researchers, designers, developers. Not for anyone who wants a conventional browser layout or a lightweight install.
- What are the alternatives to Arc?
- Zen Browser is an open-source Firefox fork with the same sidebar idea, Vivaldi and Opera offer tab stacks and workspaces in a more conventional shell, and SigmaOS chases the same workspace-browser niche on macOS.
