stagehand vs BrowserOS
AI agents and browsers for web automation compared
stagehand is a browser automation SDK that combines direct browser controls with model-assisted actions and data extraction. BrowserOS is a Chromium-based browser for local agent control and AI-assisted browsing, with a focus on using existing Chrome logins.
stagehand: Build AI Agents That Use Websites
Stagehand is a browser automation SDK for AI agents, combining Playwright-style controls with natural-language actions and structured data extraction. It supports TypeScript, Python, and Go, and can run with a local browser or Browserbase.
BrowserOS: Run AI Agents in a Chromium Browser
BrowserOS is a Chromium-based browser project with two modes: BrowserOS neo lets MCP-compatible AI agents work in your logged-in tabs, while BrowserOS adds an AI agent for people browsing. It runs on macOS, Windows, and Linux, with sessions kept on your machine.

Key differences
- stagehand provides TypeScript, Python, and Go SDKs; BrowserOS is a TypeScript project built around Chromium.
- stagehand adds natural-language actions, page observation, and schema-based extraction to browser APIs; BrowserOS provides a browser that MCP-compatible agents can control and a separate browser with a built-in AI agent.
- stagehand can use a local browser or Browserbase-hosted sessions; BrowserOS is designed to run on the user's machine and keep sessions and activity data local.
- stagehand is licensed under MIT; BrowserOS is licensed under AGPL-3.0.
- stagehand is suited to developers integrating browser automation into applications; BrowserOS is suited to people who want agents to work in an interactive, logged-in browser.
Choose stagehand if you…
- need a browser automation SDK with TypeScript, Python, or Go support.
- want model-assisted actions, page observation, or schema-validated extraction alongside direct browser controls.
- want to choose between a local browser and Browserbase-hosted sessions.
Choose BrowserOS if you…
- want an agent to use existing Chrome logins in a local browser.
- need to monitor agent sessions, run tasks in separate tabs, or replay saved sessions.
- want an AI-assisted browser for personal use, with the option to bring your own AI keys or run Ollama locally.
