  • Steel is cloud browser infrastructure for AI agents. It gives agents isolated cloud browser sessions with built-in anti-bot stealth, CAPTCHA solving and session persistence.

  • Yes. Steel Browser is the open-source server on GitHub that you can host yourself. Steel Cloud is the managed version, adding scale, stealth, proxies and CAPTCHA solving.

  • Yes. Steel works with Playwright, Puppeteer, Selenium and its own Node and Python SDKs. You connect over a standard CDP WebSocket URL, so any CDP-compatible tool works out of the box.

  • Under a second on average, with no cold-start penalty. Each session launches into its own isolated Chromium in the cloud, with its proxy, cookies and storage already set up.

  • Yes. A live session viewer lets people watch or take over running sessions. Persistent browser profiles keep cookies and session tokens, so agents pick up signed-in workflows without logging in again.

  • Steel is priced monthly by concurrent sessions, with proxies and stealth included and no per-request or idle-time fees. Steel Browser is free and open source. See steel.dev/pricing for plans.

We believe the future of browser automation is open source.

Steel Browser is built in the open on GitHub.
