On your computer
Claude Code, Codex, OpenCode, Hermes Agent, or another local agent can run the Browser Use CLI on your computer. Local computer-use CLIs such as Playwright CLI and Agent Browser fit the same shape. They can control real Chrome, with its tabs and logins, or use the single hosted browser shown in our cloud. Start with real Chrome. Connect to our cloud when a site blocks you or you need many browsers at once. Runbrowser-use auth login once before the first cloud connection.
Profile Sync copies selected cookies from real Chrome into a cloud profile. Run it explicitly for the accounts you want to use in the cloud; the dashed line does not mean automatic synchronization.
