Page Agent

open sourceexplicit relation

Page Agent is Alibaba's open-source JavaScript library that embeds an AI GUI agent directly into any web page through a single script tag injection. Unlike headless browser tools that operate externally, Page Agent works inside the DOM using text-based manipulation for natural language QA testing, enterprise copilots, and making legacy web apps AI-native. It supports BYOLLM with any model provider and requires no backend changes.

100% free and open-source in-page web automation AI agent by Alibaba under the MIT License ($0 software cost). Runs directly in client-side JavaScript via DOM dehydration without headless browsers or server infrastructure, with Model Context Protocol (MCP) integration.
