browserbase_session_create

Create or reuse a single cloud browser session with pre-configured settings via Browserbase. Ideal for tasks requiring one fully initialized browser session, including proxies, stealth, viewport, and cookies. Updates the active session for streamlined workflows.

Instructions

Create or reuse a single cloud browser session using Browserbase with fully initialized Stagehand. WARNING: This tool is for SINGLE browser workflows only. If you need multiple browser sessions running simultaneously (parallel scraping, A/B testing, multiple accounts), use 'multi_browserbase_stagehand_session_create' instead. This creates one browser session with all configuration flags (proxies, stealth, viewport, cookies, etc.) and initializes Stagehand to work with that session. Updates the active session.
