BrowserOS alternatives: 5 apps ranked by verified data

Facts checked Oct 29, 2026AppBreakup editorialHow we rank

Common reasons people leave BrowserOS: needs your own AI agent or provider keys to do anything agentic, and agents share your real logins; per-agent profile isolation is only on the roadmap. We ranked 5 alternatives by how directly each one replaces BrowserOS, then by reviews, real visits and how recently each app's facts were checked against its own website. Comet currently ranks first.
