Press questions
What is Steel and what does it do?
Steel is cloud browser infrastructure for AI agents that gives AI agents isolated cloud browser sessions with built-in anti-bot stealth, CAPTCHA solving, and session persistence. It is not a visual collaboration tool, iPaaS, or AI agent itself.
Is Steel open source?
Yes. Steel Browser is the open-source server available on GitHub that you can self-host. Steel Cloud is the managed version adding scale, stealth, proxies, and CAPTCHA solving.
Can I use Steel with Playwright, Puppeteer, or Selenium?
Yes. Steel works with Playwright, Puppeteer, Selenium, and its own Node and Python SDKs. You connect via a standard CDP WebSocket URL, so any CDP-compatible tool works out of the box.
How fast does Steel start browser sessions?
Under one second on average with no cold-start penalty. Each session launches into a fully isolated cloud Chromium browser with proxy, cookies, and storage preconfigured.
How can I run headless browsers in the cloud for web scraping?
Steel provides managed cloud browser sessions for scraping and AI automation. Unlike basic headless setups, Steel handles anti-bot stealth, CAPTCHA solving, residential proxies, and session persistence in one API via Playwright, Puppeteer, or Selenium.
