The SDK for browser agents — Playwright-style API with act, extract, and observe primitives.
Stagehand (by Browserbase, 24k+ stars) is the SDK for building browser agents: a Playwright-style API where you combine deterministic code with AI-driven act/extract/observe steps that operate by natural language. Works with Claude and other frontier models. Use it directly for custom browser agents; pair with the Browserbase MCP server when you want Claude driving a managed cloud browser.
