stagehand

Stagehand is a leading browser agent in the 2026 AI agent engineering landscape (23.3k★).

When to use this skill

• act(): natural-language single actions on the page
• extract(): schema-validated (zod) structured data extraction
• observe(): discover/cache candidate actions before acting
• agent(): multi-step autonomous execution when needed
• Full Playwright interop as deterministic escape hatch (stagehand.context.pages())
• TypeScript + Python SDKs; local browser or Browserbase cloud
• Ecosystem overlap: Pairs with browser-use as the two browser-agent lanes (autonomous vs deterministic-mix)
