Web-Agent is a Node.js library designed to turn natural language instructions into browser operations. It integrates with popular LLM providers (OpenAI, Anthropic, etc.) and controls headless or headful browsers to perform actions like scraping page data, clicking buttons, filling out forms, navigating multi-step workflows, and exporting results. Developers can define agent behaviors in code or JSON, extend via plugins, and chain tasks to build complex automation flows. It simplifies tedious web tasks, testing, and data gathering by letting AI interpret and execute them.

Browser Agent integrates OpenAI’s language models with Playwright to perform automated browsing tasks directed by natural language commands. It loads web pages, navigates links, clicks buttons, fills and submits forms, extracts structured data, captures screenshots, and evaluates custom JavaScript. By interpreting GPT output into browser actions, developers can prototype web automation workflows with minimal code. It supports multi-page sessions, cookie and session management, and error handling. Teams can script tasks such as data scraping, end-to-end testing, or dynamic content interaction, all triggered by conversational prompts. Its architecture is modular, exposing hooks for extending capabilities and integrating with downstream processing pipelines.
