BrowserOS is a privacy-first, open-source agentic browser for running AI assistants locally inside real browsing sessions instead of handing every task to a remote cloud browser.

BrowserOS is an open-source agentic browser that brings AI assistants directly into the browsing environment. Instead of sending every web task to a remote browser service, it focuses on local, privacy-first automation inside a user-controlled browser workflow.

The project is positioned as an alternative to AI-first browsers such as Perplexity Comet, Dia, and ChatGPT Atlas. Its GitHub repository describes the product as an open-source agentic browser, and the official site emphasizes local agents, privacy, and Chrome-style browsing with AI superpowers.

For developers and technical teams, BrowserOS fills the gap between browser automation frameworks and end-user AI browsers. Browser Use, Playwright, Page Agent, and BrowserMCP are strong automation building blocks, while BrowserOS is closer to a daily browser product for research, form filling, tab work, and logged-in web workflows.

The software is distributed under the AGPL-3.0 license. Model costs and privacy characteristics depend on the user’s local model or API-key configuration, so teams should still review provider settings, extension permissions, and internal browser policy before using it with sensitive accounts.

Page Agent

In-page AI browser agent via a single script tag

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.

BrowserMCP

Automate local Chrome browser via MCP

BrowserMCP is an MCP server that enables AI agents to automate a local Chrome browser — navigating pages, clicking elements, filling forms, extracting content, and taking screenshots. It gives coding agents the ability to interact with web applications the way a human would, directly from Claude Desktop, Cursor, or any MCP client.

Reliable end-to-end testing

Cross-browser E2E testing framework by Microsoft supporting Chromium, Firefox, and WebKit with one API.
