The spatial browser that put Spaces, Split View, and a sidebar-first layout ahead of tabs — now in maintenance mode while its maker builds an AI-first successor.
Our take
Still the browser to try if the standard tab bar has never made sense to you — Spaces and the sidebar remain the most-copied idea in browser UI this decade. The honest caveat: The Browser Company (now owned by Atlassian) stopped building new Arc features in 2025 to focus entirely on Dia, its AI-first browser. Arc still works and gets security patches, with no announced shutdown date.
