Stagehand ranks #7 in AI Browser Infrastructure AI search.

Stagehand is an open-source AI browser automation framework created and maintained by Browserbase, Inc. Licensed under MIT, it extends Playwright with four developer-facing primitives — act(), extract(), observe(), and agent() — that accept plain-English instructions instead of brittle CSS or XPath selectors, resolving actions via LLM inference at runtime. This hybrid design lets developers combine deterministic Playwright code for predictable steps with AI-driven actions for dynamic or unfamiliar pages. Stagehand is model-agnostic, supporting OpenAI, Anthropic, and Google Gemini via the Vercel AI SDK, and works locally on any Chromium browser or at production scale on Browserbase's cloud infrastructure. The project has accumulated over 21,000 GitHub stars and 1.4 million monthly downloads.

Stagehand is an open-source SDK for building AI-powered browser agents. It wraps Playwright with four natural-language primitives (act, extract, observe, agent) that use LLMs to make web automations self-healing and resilient to UI changes, while keeping developers in full control of each step. It is the flagship open-source project of Browserbase, Inc.
