“While spacewalking I realized something, I used to think I was scared of heights but now I know I was just scared of gravity.” ― Artemis II Astronaut Reid Wiseman




Arc spent three years proving that vertical tabs work and then died so Chrome could ship them. The Browser Company launched Arc in 2023 with a radical rethink of the browser: sidebar tabs, named Spaces, a Command Bar that replaced the URL bar, visual customization. Power users loved it. The tech press called it the future of browsing. Then internal data told a different story. Only 5.5% of daily users used more than one Space. 4.17% used Live Folders. 0.4% used Calendar Preview. The features that made Arc feel revolutionary were features almost nobody touched. CEO Josh Miller admitted it publicly: "For most people, Arc was simply too different, with too many new things to learn, for too little reward." Arc entered maintenance mode in May 2025. Atlassian acquired The Browser Company for $610M in September. The browser is dead. Today, Google shipped the one Arc feature that actually had universal demand: vertical tabs. Right-click any Chrome window. That's it. No Spaces, no Command Bar, no design philosophy. Just the vertical sidebar that every power user actually wanted. Chrome has 3.8 billion users and 71% global market share. It doesn't need to innovate. It needs to wait for smaller browsers to A/B test features with their own users, identify which ones have real demand, then absorb them. Arc's $610M exit was an acqui-hire. Chrome's vertical tabs announcement is the eulogy.
