Use the browser mode that matches the identity requirement of the task.chrome: reuse local login state
chrome browsers run in Browser-act-managed Chromium instances. They can import state from a local Chrome profile while staying isolated from the user’s daily browser after import.
Profile import
List local profiles:[!WARNING] Profile import is a snapshot. Later changes in the source Chrome profile are not automatically synchronized.
What profile import includes
Profile import is useful when a site requires an existing login but the agent should operate in an isolated browser.
chrome-direct: control current Chrome
chrome-direct controls the user’s current Chrome instance through CDP. It is useful when automation depends on local extensions, hardware-backed SSO, certificates, or state that cannot be copied safely.
Trade-offs:
- only one
chrome-directbrowser is allowed - it operates on the live user browser
- it is not intended for headed mode switching
- it is best for short tasks that need the exact local Chrome environment
Profile import vs. CDP direct
stealth: privacy mode
Privacy mode starts each session with a fresh fingerprint and empty profile:
- no login state is preserved
- an API key is required
- each session behaves like a new identity
stealth: fixed identity
Fixed-identity stealth browsers keep a stable fingerprint and proxy:
[!NOTE] Hosted static IP support may depend on account configuration and availability. Use your own fixed proxy when a stable identity is required.
