Stagehand is an SDK from Browserbase for building browser agents in TypeScript or Python. It exposes act(), extract(), and observe() primitives so you can drive a page with natural language while keeping deterministic code wherever you need it. v3 dropped its hard Playwright dependency for a modular Chrome DevTools Protocol driver.

Capabilities 3

What it actually does — grouped by capability family.

  • Browser automation (primary capability)
  • Web scraping (secondary capability)
  • Structured extraction (secondary capability)

Pros & cons

  • CDP-native v3 driver, no Playwright lock-in
  • Mix code and NL primitives
  • TypeScript and Python SDKs
  • Model-agnostic (OpenAI/Anthropic/Google)
  • SDK, not a no-code tool
  • Best paired with Browserbase cloud
  • Reliability depends on model choice
  • Newer than raw Playwright/Puppeteer

    Browser Use

    Open-source browser automation for AI agents.

    MIT-licensed Python framework that connects AI agents to a real browser to navigate, fill forms, extract data, and run multi-step web workflows. It parses the live DOM into a structured view so any model — Claude, GPT, Gemini, Qwen, DeepSeek — can act on it. A hosted Browser Use Cloud adds managed sessions and a fully-hosted agent.

    Skyvern

    Automate browser-based workflows on any website with AI.

    An AI agent that completes browser workflows — form fills, logins, data extraction, multi-step flows — by combining computer vision with LLMs rather than hand-written selectors, so a single agent generalizes across sites it has never seen. Run it via the cloud app and API or self-host the open-source engine; bring your own model (OpenAI, Anthropic, Gemini, or local Ollama).

    Playwright MCP

    Microsoft

    Microsoft's official MCP server for browser automation, driven by Playwright.

    An open-source Model Context Protocol server from Microsoft that lets LLMs and agents browse and act on the web through Playwright. It exposes 40+ tools for navigation, forms, clicking, network mocking, tracing, and more, operating on structured accessibility snapshots rather than pixels so each interactive element gets a deterministic ref. Works with Claude, VS Code, Cursor, Windsurf, and any MCP client.

    Steel

    Nen Labs

    Browser API for AI agents and apps.

    A batteries-included headless-browser sandbox that lets AI agents automate the web without managing browser infrastructure. Steel handles sessions, cookies, proxy rotation, CAPTCHA solving, and page-to-markdown/screenshot/PDF conversion behind a single API, built on Puppeteer and the Chrome DevTools Protocol. Run the open-source image locally via Docker or use Steel Cloud's managed browser fleet.
