Turn any webpage into an action manifest for AI agents
Manifest is a powerful developer tool designed to transform any webpage into a structured, machine-readable action map that AI agents can utilize. By converting web pages into detailed JSON maps, it enables AI systems to understand and interact with web elements—such as clicking, filling, and submitting—without relying on fragile selectors. This approach simplifies automation workflows, making it easier for developers to build browser agents that are more reliable and context-aware. Featuring resolved CSS and role locators, along with dependency encoding through the 'requires' field, Manifest provides a comprehensive view of interactive elements and their relationships. Its Python SDK, LangChain support, and included MCP server make it accessible for AI and automation projects, particularly for those shipping browser-based AI agents. Overall, Manifest stands out by offering a robust, API-driven solution that enhances web automation accuracy and scalability, streamlining the development process for AI-powered browser interactions.
