Get started building browser agents on the Browserbase platform

Build a fully autonomous browser agent using Stagehand Agent running on Browserbase cloud browsers. Give the agent a natural language instruction and it plans, navigates, interacts with pages, and returns structured results — no manual scripting or selector maintenance required.

Browserbase handles the cloud browser infrastructure: session management, anti-bot stealth mode, proxy rotation, and CAPTCHA solving. You focus on defining the task. The agent handles everything else.

Perfect as a starting point for building AI-powered web automation, research agents, data extraction pipelines, and multi-step workflow bots.

Steps

  1. Use Browserbase Search to find the URLs you want to explore
  2. Then use Browserbase Fetch to extract the content of the page
  3. Initialize a Stagehand session connected to a Browserbase browser
  4. Create a Stagehand Agent with a system prompt describing the task
  5. Give the agent a natural language instruction (e.g., search for a topic and summarize results)
  6. The agent autonomously navigates pages, clicks, types, and extracts data
  7. Returns structured results after completing all steps
