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.

Capabilities 2

What it actually does — grouped by capability family.

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

Pros & cons

  • Self-host via Docker or use the cloud
  • Handles sessions/proxies/CAPTCHAs
  • Page-to-markdown/screenshot/PDF
  • Framework- and model-agnostic
  • Infrastructure, not a full agent
  • Managed cloud is metered
  • Younger than incumbent scrapers
  • Needs an agent framework on top

    Browserbase

    Browserbase

    Headless browser infrastructure for AI agents.

    Managed cloud fleet of headless browsers that let AI agents browse, authenticate, and act on the web at scale. Sessions ship with stealth proxies, automated CAPTCHA solving, and observability, driven via API or the open-source Stagehand framework. Usage-based billing on top of a monthly base plan.

    Stagehand

    Browserbase

    Open-source SDK for building reliable AI browser agents.

    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.

    CDP-native v3 driver, no Playwright lock-in
    SDK, not a no-code tool

    Browser Use

    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.

    Firecrawl

    Turn any website into clean, LLM-ready data — scrape, crawl, search.

    A web data API for AI — scrape, crawl, map, and search pages into clean markdown or structured JSON, handling proxies, anti-bot, and JS rendering for you. Open-source core (AGPL) plus a hosted service; a default web-ingestion layer for agents and RAG pipelines.
