Page Agent is an open-source in-page GUI agent — a single JavaScript library gives any web page its own AI agent, no extension or backend needed.
Key features
- In-Page GUI Agent: A single JavaScript include gives any web page its own AI agent that lives inside the page, with no extension or backend required.
- Text-Based DOM Manipulation: Operates on the DOM through text — no screenshots or multi-modal LLMs, so it's lightweight and privacy-friendlier.
- Bring Your Own LLM: Works with most mainstream models and locally-deployed LLMs so teams stay in control of prompts and data.
- Optional Chrome Extension: A companion Chrome extension lifts the agent out of a single page so it can drive multi-page tasks and cross-tab workflows.
- MCP Server (Beta): An included Model Context Protocol server lets external agents connect and control Page Agent from outside the browser tab.
- Ships as an npm Package: Distributed as `page-agent` under an MIT license with TypeScript typings and a small bundle size.
