Stagehand Browser

Stagehand is an AI-powered browser automation framework designed to control web browsers using a combination of natural language and code. It aims to bridge the gap between low-level coding frameworks like Selenium, Playwright, or Puppeteer and high-level, often unpredictable, AI agents. This allows developers to choose the most appropriate method for their automation tasks: using AI for navigating unfamiliar pages and code for precise, known actions. The framework is built for developers seeking flexible, maintainable, and reliable web automations in production environments. Its key benefits include the ability to switch between AI and code, preview AI actions before execution, and leverage auto-caching and self-healing mechanisms to ensure automations remain robust even when websites change. Stagehand helps reduce the need for constant LLM inference by remembering previous actions and only involving AI when necessary, saving time and computational resources.
