Stagehand
Overview :
Stagehand is an AI-driven web browsing framework designed to simplify and expand the possibilities of web automation. It offers three straightforward APIs (act, extract, observe), which form the foundation for natural language-driven web automation. The goal of Stagehand is to provide a lightweight, configurable framework free from overly complex abstractions, supporting various models and model providers. It won't order you a pizza, but it will reliably automate the web for you.
Target Users :
The target audience consists of developers and automation testing engineers who require a reliable and flexible tool for automating web interactions and testing. Stagehand enhances productivity for developers by providing a simple API and powerful features that enable rapid construction and deployment of automation scripts.
Use Cases
- Automation testing: Use Stagehand for functionality testing on the web, ensuring the site's correctness under various user interactions.
- Data extraction: Extract specific information, such as product prices or user reviews, from complex web structures.
- User behavior simulation: Simulate user actions on the web, such as clicking, scrolling, and filling out forms, to test website performance and user experience.
Features
- Achieve complex web interactions through simple APIs: Just provide atomic commands like `act('click login button')` or `extract('find red shoes')`, and Stagehand will generate and execute the corresponding Playwright code.
- Support for multiple language models: Stagehand supports different models offered by OpenAI and Anthropic, allowing users to select the most suitable model for their tasks.
- Natural language processing: Users can intuitively control the web automation process through natural language commands without needing to dive into the underlying technical details.
- Strong flexibility and scalability: The design of Stagehand allows developers to easily add new functionalities and models to adapt to the ever-evolving web environment.
- Community support: As an open-source project, Stagehand has an active community where users can access the latest development updates and provide feedback via the Slack community.
- Caching mechanism: Stagehand supports caching of LLM responses, improving the efficiency of repeated task execution.
- Visual aids: For intricate DOM structures, Stagehand can provide annotated screenshots to assist LLMs in more accurately identifying and interacting with page elements.
How to Use
1. Install the Stagehand package: Use npm to install Stagehand and its dependencies.
2. Configure model provider: Set up the corresponding API keys based on the model provider you intend to use.
