description: Steel is the open-source browser API for AI agents and apps. The Steel
  Cloud REST API (https://api.steel.dev/v1) launches and manages cloud browser sessions,
  runs stateless quick actions (scrape, screenshot, pdf, search), and exposes a live
  session viewer, while long-running automation connects to a per-session Chrome
  DevTools Protocol (CDP) WebSocket driven with Playwright, Puppeteer, or Selenium.
  The same surface ships self-hosted under Apache-2.0 as steel-browser.
