Steel Cookbook

A collection of production-ready examples demonstrating how to build powerful browser automations with Steel. From basic Playwright scripts to advanced AI agent workflows, these examples show you how to leverage Steel's cloud browser infrastructure for reliable, scalable web automation.

• Basics: Essential examples covering browser automation fundamentals with popular frameworks like Playwright, Puppeteer, and Selenium.

• AI Agents: AI-powered browser automation using computer use models (Claude, OpenAI, Gemini) and specialized agent frameworks (Browser-use, Stagehand, CrewAI).

• Advanced Features: Steel platform capabilities including persistent profiles, credential management, browser extensions, and session reuse.
