Reviewers largely see Arc as a thoughtful, productivity-first browser that makes heavy tab use feel manageable. The most repeated praise centers on Spaces, vertical tabs, split view, keyboard shortcuts, and a clean interface that helps separate work and personal browsing. Many say it replaced Chrome or Safari, though several note a learning curve. The main complaints are practical: weak or confusing bookmarks for some users, high CPU or memory use, occasional bugs and crashes, uneven Windows support, missing extension support for some workflows, and uncertainty about Arc’s future pace of development.
