Overview

BrowserOS is an open-source browser with built-in AI agents that automate web tasks from plain-language prompts. It is positioned as a privacy-first Chrome alternative for people who want browser automation without relying on a separate app or terminal workflow.

The product runs on macOS, Windows, and Linux, supports Chrome extensions, and offers a Chromium-based browsing experience with AI features layered into the browser itself. The site highlights local execution, support for multiple AI providers, and integration with common work tools through MCP.

Features

Natural-language browser automation

Tell BrowserOS what you need in plain language, and the built-in agent handles clicking, typing, and navigation inside the browser.

Local, sandboxed execution

The browser can browse the web, read local files, and carry out multi-step workflows without requiring terminal commands or extra setup.

Bring your own AI model

Connect a model from providers such as Claude, Gemini, Kimi, OpenAI, OpenRouter, or a local runtime like Ollama and LM Studio, then switch between providers when needed.

MCP app integrations

Use 40+ built-in integrations through MCP for apps such as Gmail, Slack, Notion, and Calendar, and add custom MCP servers when needed.

Scheduled workflows and automation

Schedule tasks to run automatically and build workflows with loops and conditions for repeatable browser operations.

Terminal access via MCP server

Use the bundled BrowserOS MCP server with Claude Code, Gemini CLI, or Codex to control browser tasks from the terminal.
