What is Steel?
Steel is an open-source headless browser API that gives AI agents browser sessions with proxies, CAPTCHA solving and session persistence. Developers can self-host it or rent capacity on Steel Cloud.
Agents connect through Playwright, Puppeteer or Selenium, and Steel manages the browser lifecycle, fingerprints and cookies. A CLI and agent skill let coding agents run browser tasks and get back markdown, screenshots or PDFs. It is often chosen as an open-source alternative to managed browser services.
