Stagehand — Browserbase's library for building reliable AI agents on top of Playwright with structured actions. Built on top of Playwright, inheriting its browser automation capabilities.
About Stagehand
Stagehand is Browserbase's open-source library for building AI agents on top of Playwright using structured actions.
It inherits Playwright's browser automation and adds structured methods — act, extract, observe, and agent — for AI-driven browsing, and it works across multiple model providers including OpenAI, Anthropic, and Google.
It's aimed at developers building browser agents who already work with Playwright and want model-agnostic structure. Two caveats: you bring your own API keys for the model providers, and browser-based automation is inherently slower than direct API integrations.
Against other browser-automation options, Stagehand's angle is layering AI agent primitives onto Playwright rather than replacing it, so existing Playwright knowledge carries over.
